Sauerbraten is a free multiplayer/singleplayer first person shooter, built as a major redesign of the Cube FPS.

Much like the original Cube, the aim of this game is not necessarily to produce the most features & eyecandy possible, but rather to allow map/geometry editing to be done dynamically in-game, to create fun gameplay and an elegant engine.

The engine supporting the game is entirely original in code & design, and its code is Open Source (ZLIB license, read the docs for more on how you can use the engine).

In addition to the FPS game which is in a very playable state, the engine is being used for an RPG which is in the preproduction phase. Additionally, Proper Games ltd are the first to use the engine commercially.

It looks quite good.. perhaps something worth to try out!

so will it have RPG elements?

So does this mean that I (as a player) am able to blow holes in walls and similar?

I think what that means is you can build things in game, ala' second life.

hahaha what a name for a game sauerbraten means in german a grilled pig lol

Lets play with the grilled pig! xD Looks kinda... boringzor.. :p

It runs horrible if your graphics card is old, trust me, the engine derives all the power out of your graphics card, not RAM or CPU really. it even says its rendering method is very brute. not one for the integrated. xD

My gfx card sucks, yet I had 199 FPS (it flipped from 200 to 199 all the time)

zonoes proven wrong on the internets!
