You're fairly aware by now of how Team Xtender's XFPS was all set to shake up the FPS realm on the Xbox 360 by giving gamers the ability to use the undisputed king of controls (that'd be the keyboard / mouse tandem) -- or Sony's widely adored Dual Shock controller -- instead of Microsoft's own rendition, but according to Xbox360Fanboy's review, it's not quite the post-Christmas miracle we were all hoping for. While expectations were admittedly set rather high, it seems the unit simply underperforms where it mattered most, and excelled in a somewhat less important department. Using Gears of War, Halo 2, and Rainbow Six 3: Vegas Demo as tests, reviewers found the keyboard / mouse setup to be a breeze, but actual in-game results were not only poor, but relatively unacceptable. If the "slight button delays" weren't enough to turn your nose up, the simply inability for a keyboard to emulate the "analog support of the Xbox 360 controller" made critical run / crouch movements next to impossible to pull off, and the mouse aiming was purportedly dreadful as well. It was stated, however, that it worked perfectly with a Dual Shock (PS1 or PS2 flavor) controller, so folks digging the Sony design but unable to locate (or afford) a PS3 should take note. Overall, the XFPS reportedly fails fairly miserably at giving Xbox 360 owners the chance to use their keyboard / mouse combo to shoot it up on a console, and just seems relatively expensive for a simple Dual Shock-to-Xbox 360 liaison, so unless you just have to learn things the hard way, we'd suggest holding off.
