Yesterday I purchased Tom Clancy's Splinter Cell: Chaos Theory from XBLA (which does have splitsceen co-op) and it made me realize, what ever happend to that Project Stealth game, to any of you don't know, Project Stealth was a project (no pun intended) of a game that plays exactly like splinter cell's spy vs mercenary multiplayer, here is more info:http://en.wikipedia.org/wiki/Project_Stealth

the thing I do not know is that is the game out already or is it still in development?

wkiipedia says it's still TBA but why is there a reception section? That implies that the game is released already?

The official site says it'll be released when it's done, and the moddb page has a few months old update.

I'm guessing the reception is some kind of alpha build or internet vote. You know, like how if Diablo 3 had been in GOTY 2011 votings, it could've won :p

So anyway, it ain't out yet.
