a set of new maps started to show up in rotation on MW3 that i downloaded last week on xbox. Gulch, Foundation, and a lot more.these are maps from old MW2 and COD4 right? got to tell you its like playing a new MW3. it seems these maps are different and like Gulch more than 3 firing lanes.and Foundation is really cool.Gulch for some reason has the same feel as Blackops2 Cove. if you get a chance check out MW3's STORE a lot of these maps are free and fun to play.
