MIG-31

Since the release of Nexuiz 1.0 in 2005, we have been tracking its progress as one of the leading open-source first person shooters. With time, this fast-pace game has picked up a nice level of artificial intelligence for its in-game bots, engine optimizations, single-player campaign missions, and a variety of technical advancements. Nexuiz has always been one of the leading open-source first person shooter games, and with the release of Nexuiz 2.4 yesterday it reaffirms that you don't need to be a major game studio -- or a game studio at all -- to develop a quality title and even for being a free software game it has impressive graphics. With the graphical settings near maximized, a GeForce 8600GT on a quad-core system was brought to its knees by this free software (and free content) game.
