This is not a replica of the thread found here. But that thread shall give you more info. Please note this game is not available for Linux and seems unlikely to be run via WINE, Cedega or something (due to heavy DirectX usage).

It is called .kkrieger and it resembles Quake 3. It requires lot of processing power and RAM though. In the size of 96k, it's an amazing thing. It uses real-time rendering thus allowing the games level 1 fit into just 96k (yes, with sounds too). Check the above link for screenshots.

If you are thinking why this post is in Linux Games forum, just to mention an intersting concept. If you know any Linux game/graphics/animation programmer ask them to have a look at the above thread too, so that we might be having a Linux interest in future.
