Commander Keen - Doom of Mars 1.0

After defeating Mortimer McMire's robot army, Commander Keen has a new mission on Mars. The Vorticons, Martians and Gnosticenes have built a new teleporter system that will allow them to travel from planet to planet through a portal that opens another dimension.

At his arrival on Mars, Keen notices that the teleporter system is running but no one is there to report the situation. Reach the teleporter room and shut it down before the whole place blows up.
