I'm in the beta and we've been playing on a 2 month old build. They just recently said they were working on the blood effects which won't get put in until the public beta so don't worry. You'll see them. The aliens at the end were kind of like boss creatures which is why you'll notice the shields above their head indicating they have more health. Basically it was designed that way so again, don't worry. The game really is fun though. This vid (which personally think looks pretty good) shouldn't stop you from buying the game.

Split screen co-op campaign and an 8 player co-op.

@BILL COSBY!!!

can u give us some details ??

numbers of weapons ??

big enemy ?? size ??

and also, how much of ally/enemy on screen at the same time ??

looks great

nice

nice.. look forward to this game :p

very nice, but the shield can be put on invisible or its going to be getting in theway all the time you have it on? cause that thing is prety anoying.

I personally don't have problems seeing through and there isn't really a way to make it invisible because the other people in multiplayer need to see it's up in order to react to the situation properly. I guess you can walk around without one. BTW that isn't the final look for the shield either.

Wow, Im not a big COD4 player, but if I think alot of COD4 fans will pick this up. Because of the co-op I think ill pick it up too, it adds alot of fun replay value.
