This is a bit longer than most IFComp games; I didn't like it at first, but it really grew on me. In this game, you have to sneak onto a spaceship (a tedious opening sequence). Afterwards, you get to space and discover the (strongly telegraphed from the beginning) secret that the aliens are out to get the humans!
The game has some unusually graphic violence for a sci fi romp as you take down 6 aliens using a variety of devices and items scattered around the spaceship.
I had trouble transferring items from one location to another for a while, until I realized that you later gain the capability of returning to some locations (not the initial one, however).
The hints were incomplete, which made this game more difficult than me (as I always use hints). But I still finished it, and enjoyed it.
