I don't know if you want to design an expansion for this game (it will be great !!!)
But please we have women and girlfriends playing with us.
It's really hard to make her playing on such a game with big guns, numerous ennemies and bloodbath.
How can we interest her if the only character she can play is a body-buildy spacemarine ? (forgive my bad english i'm french)
I don't know the video game and don't know if there are female character but please put them in the game, we can imagine a sniper girl or an intelligence or medic woman...
