Tired of this game, 1:36 in Space city.

I can't even get out of the building without dying. 1:36, that's it. How the hell can I play the map if I can't even explore it? kinda ridiculous. Only have two Easy Maps to play is stupid. What's the point? I had to kill 3 bots with a marksmans rifle for two missions. Never had a chance. Bah. Need the gear caps and easy mode in other maps.
