KKrieger is a short Doom-clone with a great graphic ( althought with basic AI and some bugs ). This is nothing special but what is really incredible about KKrieger is that its size is only 95 KB ( this game use heavily procedutal algorithms, like Spore ).

This freeware game was release in 2004 and was the first of 3 levels.

The "official" minimum specs for .kkrieger: chapter 1 beta are:

• A 1.5GHz pentium 3 / athlon or faster.
• 512MB of RAM.
• a GeForce4Ti (or higher) or ATI Radeon8500 (or higher) graphics card supporting pixel shaders 1.3, preferably with 128MB or more of VRAM.
• some kind of sound hardware.
• DirectX 9.0b.

Absolutely insane !!! If you don't believe me , play it . Enjoy. 

lol i've known about it for ages. I'm waiting on them to continue the game.

That is amazing!!!!! 96 KB!!

Welcome to 2004. Some people should learn from these guys. Procedural generation is the future, not TONS-O-GIGS discs.

Tell that to the Japanese devs!

actually the 96kb is a lie. It installs a large chunk of data into your temp files while the game loads up. The data is deleted when you exit the game.

 what he said

 i've been very interested in the work these guys have done for quite some time now (although, nothing new has surfaced recently) , i wonder if they'll finish off this game

 I'm pretty sure they said that on their website. That's why loading times are so extensive, it's generating all the stuff and such.

Imagine what these guys could do with blu ray.

How the size is achieved

.kkrieger makes extensive use of procedural generation methods:

• Textures are stored via their creation history instead of a per-pixel basis, thus only requiring the history data (possibly as low as ~300 bytes per texture at any resolution) and the generator code to be compiled into the executable, producing a relatively small file size.
• Meshes are created from basic solids such as boxes and cylinders, which are then deformed to achieve the desired shape - essentially a special way of box modeling.

These two generation processes explain the extensive loading time of the game - all assets of the gameplay are reproduced during the loading phase.

The game music and sounds are produced by a multifunctional synthesizer called V2, which is fed a continuous stream of MIDI data. The synthesizer then produces the music in realtime.
