Although not in the beta, i was picking suit modules, when hovering over the Heavy Weapon Pro, the example footage showed footage from a destroyed/junglelized Skyline, layout seems the same

Other maps:

Something with a Bunker, maybe the Trainyard map
Destroyed Buildings and a Wrecked ship and some chinese arch. maybe a Chinatown map
A map on the Hydro Dam as showed in the trailers

Gamemodes:
Domination- seems like 3 points were you have to capure Alien Spears


I got this stuff from watching the small vids on the Module Selection Screen
