Well I just picked up Medal of Honor Heroes 2 today. Planned on getting both it and Umbrella Chronicles but the only copies of UC they had were preorders. :/
ANyway, MoH:H2 is pretty decent and IGN was pretty accurate in it sporting even better controls than MP3: Corruption, mainly because it boasts just as tight a layout but on top of that allows the option to resize the bounding box as you see fit so there is no excuse about that being a problem; at least in this game. Single player wise, pretty decent thus far and the way it plays reminds me a lot more of the earlier MoH titles as well as European Assault; not sure what the heck happened with the other games but I didn't like them at all, so I'm digging the style of this one. The gesture based controls for various weapons seems somewhat silly at first, but they work pretty darn well despite some of the motions you have to make. As such, the shotgun is still a fav. of mine since you get to actively make the pump action to cock it - silly as I mentioned before, but it feels good after blasting a dude in the face and then going in for another round.
Online wise, for a Wii game it's...well, the only online FPS on the system and pretty bare bones overall (only deathmatch, team deathmatch and CTF) despite EA hosting the online service instead of Nintendo's for it. Everything runs smoothly, lag free, 32 players, arenas are pretty varied and the game makes changes accordingly to balance the field of battle as people drop out and jump into games freely as a match is going on.
I don't plan on putting much time into the online till Galaxy is done so I'm jumping in and out casually just to get a taste of how things are going.
