One of the better FPS campaigns I have played. The pilot's mobility is so much fun to utilize and there are a lot of really cool guns you can use. The titan is pretty fun too for a little dose of power fantasy. What really makes it great though is the Effect and Cause level which allows you to bounce between the past and present at the push of a button. Super frickin sick level. The multiplayer is also good I guess, but mostly just played this game for the single player.
