So for a few nights I didn't have Xbox Live and I decided to play the COD4 Campaign. I came across something weird. On the mission War Pig, in the building where you can find the Intelligence, there's the teddy bear from the new Nazi Zombies map on WaW sitting on the bed. I thought this was creepy enough because I never noticed it before. Then I played the mission All Ghillied Up (or the one afterwards, I forgot if they're both the same) and at the part where you have to carry your captain to safety, there's a corridor where the teddy bear is leaned against a table leg.
Anyway, what I'm trying to get at is, is the teddy bear found somewhere on every map? I never noticed it before.
