Machinima.com has released a new three minute video of the upcoming arena-style first-person shooter Nexuiz from Illfonic and THQ. The video shows off plenty of fast paced run and gun style gameplay while the narrator explains how the game’s mutators work. In a nut shell, every time you earn a 5-kill streak, capture a flag, or pick up certain power ups on a map, you get several different options to “mutate” your combat style. The video focuses on mutators that grant you bigger and deadlier weapons, but it also mentions several other styles of mutators obtainable in the game which range from team buffs to silly sound effects. There are over 100 of them in the game, so use your imagination! Start planning your strategies and sharpening your skills, Nexuiz will be launching on February 29 as part of Microsoft’s House Party promotion.
