Ok, check this out guys, if you beat COD:WW, you get this Zombie mode, and you can play 4 player co-op on it.
As for the beta, i've been playing it for a while now and its getting close to the release date. I'll give a quick rundown for anybody who is interested. Not counting Bigs, since a certain member of this board was kind enough to give him a code for the beta.
Well there are obvious reviews on different game sites like ign where they show you what maps, modes and all that. So i'll give my impressions. I've been playing mostly Hardcore team deathmatch and hardcore search and destroy. They are basically the same as COD4. I've also played capture the flag and War which are both really fun. I think Hardcore is where you get the most balance on the weapons. In regular mode, the automatic weapons have a huge advantage. The bolt action rifles can kill in one hit if you get a headshot, but if you don't get a headshot, you're screwed.
I like the semi auto weapons and the trench gun. The trench gun is a shotgun and you can basically shoot arms and legs off, or blow holes in the sides of people. The mines in the game are fun too, the bouncing betty's. Basically like claymores except when you trigger one it pops up and your lower half blows off. So far, the only problems with the beta is a glitch on one map where everybody goes under and kills you and you can't see them. Also, the spawns are pretty messed up , and sometimes you kill an enemy and they spawn right where they died and they shoot you in the back. Supposedly the developers fixed these problems for the actual release.
The artillery strikes are like the airstrikes but they seem to stun you more then kill you, unless you get a direct hit. Its very effective though. The dogs can be ridiculously effective. But you can kill them and i'm getting decent at that.
The 3 maps you get show some good detail. These aren't huge maps but they have lots of places to hide, and i think treyarch might have brought some cool map designs to this game.
Overall, it's a slower paced WWII version of COD4. I'll be gettin it, just thought i'd let you guys in on the game a little.
