Space Gun

The success of past explorations was causing the space effort to grow by leaps and bounds, but this time, the explorers had found little more than fungus and small insects as alternative lifeforms. The chief dangers were those posed by the hostile environment of space, and the aliens had not known about humanity until now.

On the ragged edge of the galaxy, other creatures that roam the stars discover humans and spaceships to be excellent sources of food and other resources. The human crews can do little to defend themselves as wave upon wave of nightmare creatures descend upon their ships and bases.

You are the leader of a rescue team assembled by the Federation in response to their distress calls. Your mission is to gun down the intruders, pick up human survivors, and brave the maze of dark corridors that may lead to a deadly shootout with legions of monsters. Along the way, you can pick up extra ammo to aid you in your fight.
