Xcom: A Game About Exploration

The game is almost like a version of xcom that's like real time but also every map is that final map. The idea here is that the longer your guys stay in there the more bad shit happens to them. Marines can do less damage and they're going to consume more ammo to do less damage so now you're squas less effective maybe this is a moment to retreat back to your transport  and say let's go let's get out.
