Spaceship Monster Escape

This spaceship was built after years of hard work and researches. Now it is all set to take a group of common men for a trip to space. You are one in the group. The long wait ends and the spaceship takes off and lands in one of the space stations in outer space. There a weird looking monster enters the spaceship and starts killing people on board. This chaotic mayhem has to be stopped immediately and you must take up the challenge to stop it. Your am should be to dispose the monster out of the spacecraft. It will not be an easy thing to do but it is a better option than waiting to be killed.
