A very interesting setting, great use of wide and open areas, with some funny comments on some notes. You must attack a base full of grunts in a snowy mountain to which you come in a really fancy spaceship that carries a container. Unlocking doors and finding alternate routes until you make enough of a problem to let a few aliens invade as well.
Everything is complete, the map is gorgeous, the enemies are there, the doors work. Everything works, but one thing. Again, the map has no ending. What seems to be the ending area cannot be unlocked or accessed using normal means. The area behind that door leads to an elevator where I assume the map should end. Again with a little ripent, this map can have an ending.
