I definintely reccomend it. It was Given an 8.6 and an editor's choice award by IGN.
The graphics make you wonder if you are playing a PS3 or a Wii.
The single player is fun, not just a run and gun, you actually have to plan ahead.
Alien Guns!
Every single person I ask says that The Conduit's online play is fun, but I find it sort of frustrating. I always end up being followed and when I'm not looking, killed from behind. Then again it is only me, everyone else seems to like it.
Tons of achievements to keep you coming back, I have them all and I still play the game a lot.
