From what I saw of singularity, it looks pretty cool. Like some kind of F.E.A.R. and Bioshock hybrid. Even the multiplayer looks incredibly fun, like some kind of L4D versus on steroids.
I also want to try out Sniper GW, and there was some demo a while back but I think it was leaked or at least "unofficial" because it wasn't on any of the usual sites like Fileshack, Filefront, etc. but I am seriously dieing to play a new stealth game, especially one with "realistic" sniping.
