20 Glorious, Uninterrupted Years Online!!!!
"Reaper Bots Cheat"
One tremendous advantage Quake has over other online games is that you can practice the skills and techniques necessary for survival online in an offline environment.
This is possible due to the creation of Bots. The Reaper was one such bot. Created by Steven Polge with an artificial intelligence that at first, seems so well executed, you'll swear you are playing against real gamers.
Steven has spent the last 20 years toiling for the same gaming company and is currently programming the AI for their next release. The game will be an update of Unreal Tournament.
As you travel around and explore other Quake sites online you will likely see other posted raves concerning the Reaper. What you will likely not encounter however is any negative feedback.
Now there is a lot of goodwill towards men on the net, especially concerning free addons to games like Quake. I mean the amount of time invested to produce these addons is enormous.
My complaint with the Reaper has more to do with the reaprb80.txt file included with the bot, than the problem with the bot itself. In the text file Steven explains that "This bot does not cheat!" He goes on to say they follow the same rules as you. Okay, beautiful.
However, this is not the case.
All's Fair in Love, War and Reaper Bots
Things the Reaper can do, that you cannot include:
Ability to grab the rocket or grenade launcher without being physically near it. You gotta love it when you are out of rockets and like a mirage of an oasis in the desert, the rocket launcher vanishes into thin air just as you reach out to partake of its life giving bounty.
Faster rate of fire. From rockets to nails the Reaper has you beat on quantity, so you better be focusing on quality shots.
Perfect Aim. A Reaper will never miss its target when firing the shotgun. I have been fragged more times by this weapon than all the others combined. Not very realistic.
Okay, so maybe you're saying to yourself, "Hey these are minor complaints for a free bot." Granted, however as I stated earlier, Steven was able to use the publicity provided a Quake add-on as a springboard to a new career.
Would it be within the scope of reason to assume that the attention the Quake gamers brought to the Reaper were just as responsible for this new career as the creation of the bot itself?
And if so, would that bring along with it some form of obligation to point out obvious game bugs, if indeed they are bugs and not programmed advantages?

The Reaper Bot makes a worthy adversary because it can "remember". Using "Dynamic mapping", the Reaper can easily return to places in a Quake level that it has previously been.
This is accomplished by the Reapers opponent (you), dropping "digital bread crumbs" or nodes at certain locations in a level that serve as the Reapers road map.
Here is a screenshot of the "digital bread crumbs" that I left behind me for the Reapers to follow.
This incredible bit of coding is the reason you will rarely face an unarmed bot, as well as, giving the player the impression that the Reaper is competing with him for the powerful items, just like an online human opponent would.
Obviously there is a problem with this scenario.
The Reaper must "live" long enough for it to map out portions of the level. Accordingly, this is one Bot that will not hesitate to "run like hell" when outgunned or low on health.
Also, the Reaper is in no rush to seek the human player out and risk possible death. The Bot is often very content to wait for the player, all the while entertaining itself by constantly ramming straight ahead into the nearest wall.
In an attempt to reduce the occurrence of this "camper-like" behavior, I believe the Reaper was coded so that it could "teleport" weapons back to itself when respawning.
By "calling" the FL_Client, the Reaper, in the unpatched version, is able to obtain one of the powerful weapons it finds along its BotPath.
Being armed at respawn would immediately enable the Reaper the freedom to move, thus breaking the chains of "fear" that is so strongly coded into its personality.

The Reformed Reaper
UPDATE: 3-29-13Hey, it's only been 11 years since my last update. Hello? Anyone there?
Download the Reformed Reaper Bot.
Here is the Progs.dat file (compressed down to 171 KB), that I have patched that corrects the following problems and adds the following features to the Reaper:
Watcher Mode - added Watcher Mode that allows you to view the action from the air or to travel through walls. Just bind impulse 13 to a key and your off.
KasCam - added the KasCam that allows you the option to view the action from the bots or a human players perspective.
Speaking Reapers - The Reapers will now thank you for decompiling their source code and setting them free.
Reaper Timeout - The Reapers will now stop fighting each other and racking up frags, during the intermission between levels. Don't know why that bothered me, but it did. So, now it's fixed. No need to thank me.
Color Matching Reapers - Reapers now appear in the game wearing the same colors as the ones displaying their frag count on the Scoreboard Screen.
Location Damage - Aim for the HEAD!!! If you want to score the most damage. Aim for the legs if being fragged is your thing.
Disappearing Weapons - fixed this bug as well as, ensured your not automatically switched to another weapon while you still have one rocket or grenade left.
Axe Murderer - the Reaper will now finish off an opponent using the Axe in certain situations. Spawn four bots and see just how often that "situation" arises.
Random Skills - now you might face a 3, 2, 2.5, 1.5 etc. skill bot. Better be on your toes!
Bounce the Reaper - added the ability of the Reaper to be "bounced" around by rocket or grenade explosions.
Fixed Bleeding Doors - Doors and platforms triggered by being shot will no longer bleed, but will now show the correct damage.
Corrected Reaper Sounds - reduced the damn "splash noise" the Bot makes at respawn and the Reaper also now makes the correct sound when jumping.
DeathMatch Timer - added a timer that counts down the time remaining in a DM when the timelimit command is used.
DeathMatch 3 - added DM 3 rules. Just specify "deathmatch 3" in your autoexec.cfg file and your all set.
Reapers on the Scoreboard - finally got around to adding this much wanted feature of the bots and player frag totals both appearing on screen. Feel free to rename them!
Here is the Reformed Reaper Bot Source code (compressed down to 110 KB). Just unzip and you will be able to get a look at the code inside any file by simply opening it with a text editor.
The Reaper Bot, even with its flaws, still stands as a symbol of the possibility that a major breakthrough in the improvement of gaming AI is near.
Artificial Intelligence has long been the Achilles heel of computer games. Reaper author Steven Polge promises just such a revolutionary AI to premiere in the game Unreal.
As Steven himself admits, the Reaper Bot code is a far cry from this promised new AI. Although buggy and unfinished, Steven has publicly refused to release its source code.
This is a sad mistake on his part and totally unnecessary since the Reaper source code has been available to everyone who wants it since June of '97.
The tragic part of this is the loss of gaming AI insight the Quake community could have acquired if only Steven would have approached one of the many interested parties in the Bot and given them the source code. They could have rid the Bot of its many bugs, while Steven would still retain top author billing.
By not doing this the inevitable has happened. All sorts of "new and improved" bots have surfaced, many of them just blatant Reaper rip-offs. Imitating Steve Polge's ignorant behavior, not one of these authors has released their source code either.
The author of the Omicron Bot has gone so far as to state that he would not release that bots source code because it would not be "too cool to see Omicron clones floating around".
What a dumbass!
The Dark Side of the Quake Community
The attempted improvement of the Reaper Bot has revealed a negative side of the online Quake Community. Certain web sites dedicated to providing information on Quake, have instead become id's and any other mod author's, bitch. As a result, the info on the site can no longer be trusted as accurate or unbiased.
The inside 3d site fits this description. A visitor to this page has to tolerate daily rants or just plain dumbass statements posted by its numerous editors. Most of which are mindless worship of id.
The most incredible example of this is the recent article posted by one of the editors of inside 3d in response to criticism of id and Activision titled, You'll get peas and like it". I heard the planned title was supposed to be, "You'll get it in the ass and love it", but was toned down. This article sets the standard for mindless, slave-like obedience.
The Omicron Bot was hyped by the inside 3d ass kissers on a daily basis for a full month before its release. This hype was the same kind little kids use to irritate other children, along the lines of, "I got something you don't and you can't have it."
This behavior really hurts this otherwise useful site that store lots of informative tutorials on how to modify Quake and other 3d games. However, reading these tutorials can be an unpleasant experience due to the arrogant way in which some of them are written.
The "rip" tutorials focus on improving the Reaper Bot. Numerous bugs are promised to be fixed, but only by following these tutorials and modifying the existing Reaper code yourself.
Instead of simply providing the patch along with the tutorial, only the tutorial is provided. It seems the author is very frightened of copyright laws. This bullshit regarding copyright law was my main motivation for posting not only the patch, but also the Reaper Bot source code.
The author of these tutorials is also interested in a lot of personal horn blowing and has seemingly provided this info in an attempt to feed a huge ego. The author seems to revel in pointing out the obvious and reminding you of just what a stupid ass you'll be if you don't make the right coding changes.
Warning: Be prepared for one of those sites that continually remind you that this is serious programming material and lamers need not apply.
Taking a cue from Steven Polge not answering his email, the site author states, several times, that he will not be answering any of yours, as well. So if you have a problem take it somewhere else.
On a positive note though, these tutorials are easy to understand and making the necessary changes has been a snap.
Which just makes it more of a aggravating mystery why Steven has never bothered to release an updated version that would have matched the claims he boasted of in the Reaper Bot .txt file.
A Letter to Blue
I created this page in Sept. of '97 to expand on statements I made earlier in the month in an email to Blue of Bluesnews.
The purpose of the email was actually to point out to Blue how his continuing censorship of Quake news was detrimental to the Quake community as a whole.
To be honest, the only reason I sent it was due to the entire page on Blue's site that explains why Blue doesn't respond to his mail. I wasn't seeking a reply, I only wanted to make a point about Blues policy on publishing certain news stories.
I was shocked to find it heading up the mailbag section. I'd never remembered Blue having one, I thought that was a Planet Quake thing. Blue responded by misinterpreting my letter as being only about Steven Polge and the Reaper.
I was surprised by the responses my letter received, most of which criticized my views regarding the Reaper. Until then I didn't realize just how big this story was and still is.
Read my email and the replies it received.
The Inside Scoop?
An article that is supposed to give an accurate review of the pros and cons of the Reaper Bot can be found at the Ramshackle site.
I have a mixed reaction to this article. The author acknowledges the "vanishing weapon" bug, but says that the Reaper is not retrieving the weapon. He takes this as the truth because his "advisors" say so. For some reason this article took 3 people to write.
The "vanishing weapon" bug is one of my biggest beefs with the Reaper. I believe that it is a programmed advantage given the Bot to improve its competitiveness and having played with a "patched" Bot I must tell you it is not nearly as strong an opponent without this advantage.
The reason I know the Reaper is obtaining the disappearing weapons is because my favorite level to challenge the bots on used to be E1M7. If you're familiar with this level you know that the only RL is located upstairs. On more than one occasion, I watched this weapon vanish after spawning the bots. Since I was the only one upstairs I thought Quake had a bug only to find myself the target of rockets being fired from below.
I found an old Usenet post using dejanews that contains a quote from Steven Polge were he confirms that the bots are able to acquire a weapon when respawning by teleporting the weapon to them. You can read the original post here.
While the article does a good job of presenting the information with graphics to assist in illustrating its points, the author concludes with a useless sermon in praise of Polge.
I would like to again point out that software running on your machine is yours to do with what you like as long as it stays on your machine. The author credits Polge with "giving" you the right to patch the Bot.
Steven doesn't have this right to give.
The Omicron Bot
The Omicron Bot version 1.01 has been released and is available at the Ramshackle site.
The inside 3d web site mentions that the release of a "Reaper Killer" is near at hand. The site has quite a bit to say regarding the new Omicron Bot.
It seems the author battled one of the bots in the DM4 level and recorded a couple of demos of the festivities. One of the demos uses a Bot cam to give you the perspective of the robot.
Not recommended for those of you who easily suffer from the effects of motion sickness.
For when this Bot is not performing leaping, 180 degree, twist turning frags, it spins around like a top. I suggest viewing the "obots1" demo in your favorite "altered state".
The Bot cam provides great insight as to the future potential of the Omicron. However, it also vividly points out this bots "flaws".
The demos and an article previewing the Bot are available at the Ramshackle site.
"Rumors in the Air"
The Reaper has consistently shown the ability to make headlines in the Quake community.
On Sept. 8th, MeccaWorld reported a rumor that was making the rounds at ECTS. The story was that Quake 2 was going to use the Reaper Bot source code to improve its monster AI.
At first glance, I thought big deal, I mean its only a rumor. Well it seems id thought differently and issued a statement saying in essence,
"Untrue, because we
1) Have never seen the source code.
2) Quake 2 doesn't use Quake."
It would seem that the staff at id is just about the only ones who "haven't" seen the Reaper source. This kind of comment makes you wonder about the "new-post Romero id".
There has been talk that id is starting to become more like a corporation every day. This denial would do any corporate PR exec. proud.
For the record, the Reaper Bot source code has been available online since the end of June of this year. Several prominent addons have merged the Reaper source with their progs.dat file.
Somehow this quote saying id has never seen the source just doesn't seem true.
I love the second reason the most, id must think gamers are idiots. Okay id, I believe you, I mean it would be impossible to convert QuakeC to C, C++, Pascal, ASM, Ada, Basic, Fortran, Cobol or even Java for that matter.
The first reason was iffy enough, but this one is an insult.
Despite this, MeccaWorld followed up on Sept. 10th with the typical "kiss id's ass" feature saying,
There were rumors floating around ECTS on Monday that id Software might have taken the Reaper Bot source code and used it in Quake 2. So, on Monday, we made the mistake of mentioning these unfounded and UNTRUE rumors -- We should have had more sense than that. The truth is, the rumors are untrue, and we apologize to id Software for letting that slip through and we have removed the mention. If fact, id Software has replied regarding the rumors saying that... "No (it's not true). Considering that; a) We've never seen the reaper Bot source and b) Quake II doesn't use QuakeC."
We're sure that John Cash and company are coming up with some new stuff that will blow us away. Now back to the most "amazing" ECTS coverage on the Internet. :)
The only "amazing" thing about MeccaWorld's coverage is how fast they can make a story disappear.
Notice how willing this "journalist" is to admit error, "The truth is, the rumors are untrue...".
Damn, that's it. id says untrue and that makes it so. I can start to see why id sometimes treats the gaming community with such disdain, I mean people will only show you the respect you deserve.
MeccaWorld publishes "facts" as if they were putting out the id company newsletter.
The story doesn't end here, no matter how much MeccaWorld seems to want it to.
John Cash posted a .plan file saying that Steven Polge had sent him a copy of the Reaper source code for, as John put it, research. John went on to say that even though he had the source, he never even bothered to look at it.
John said that only he and nobody else at id had access to the Reaper code. Wow! It seems incredible that he would have this much ballyhooed code in his hands and decide not to look at it himself, much less, keep it secret from everyone else at id.
Furthermore, John said that after Steven took the job on Unreal, he decided against using the code for even a research base. The .plan file concludes that John just wanted to clear this matter up because Steven is a good guy, doing good work.
Out of the entire statement, it is the last line, about Steven doing "good work", that bothers me the most. I mean he just stated he never looked at the guys code, so how does he know its good.
In Logic, a definition of a true statement is its absence of contradictions. The last line of the .plan file contains a contradiction that would seem to cast some doubt as to this .plan files validity.
Maybe John should have looked at the source code, since the guy who created the Omicron Bot was hired by id when Cash was unable to get the bots working right for Quake 3 Arena.
