There is a multiplayer component as well just to let you know Sledge but it's completely optional (just like ME3's was (well was supposed to be but I won't get into that)).
It looks amazing and the gun play looks a lot better then it ever has been but they just couldn't let go of the fucking ammo component could they. Sigh, it'd be nice to have ME1's infinite ammo/cooling system back. Sadly I don't know how hyped I'll really be until I see powers. I know they've done away with classes for the Pathfinder (which blows, I loved the one class aspect of ME) but I really want to know what powers are going to be in this one. Can I make my Pathfinder exactly like my Sentinel (by far the best class imo from ME2 and ME3 (best of both Tech and Biotic powers)? Can I shift more toward an Infiltrator build? I know I'm asking a lot here but a lot is riding on what is available to my character (I really want to play a Sentinel, that Tech Armor plus Biotic Powers was amazing).
