wouldn't a female marine take away from the MANLINESS of the game?
also, Rosie the Riveter is mentioned in the description of the weapon "Rosie" it is a shotgun with explosive rounds
a survival/hard mode is a must.
i think there needs to be more variety in the chassis, there are only 6 (i think) to pick from and the rest are just more armored versions. maybe there could be a medium chassis with 2 left slots and 1 right slot, and has one emplacement slot for each type. or an engineering with only 1 weapon slot, but 3 heavies and a support. also some more powerful versions of rares from earlier in the game would be cool. like a more powerful "jackhammer" shotgun, or stronger Experimental device. they had cool effects, but just aren't good enough to use in the later levels. I think some more variety in the trench parts could go a long way.
