The PS3 version of uber frag-fest Unreal Tournament 3 will let you headshot your opponents using a keyboard and mouse.
Epic’s dominating video game series will offer support for both the Sixsxis and a USB keyboard and mouse combination. This should come as a delight to PC gamers whose rigs will (most likely) fall shy of the recommended specs for the game.
The Sixaxis controls will work in the time-honoured GoldenEye 007 way, but with an optional twist. The motions sensor in the joypad can be used to look around rather then the right thumbstick. According to a Sony rep "it is actually very accurate once you get the hang of it".
Whether you feel like using motion sensing in such a way is "wicked sick", or if you feel "Godlike" using tried-and-tested PC controls, your needs will be catered for.
UT3 is currently slated for a late 2007 release.
