Exector

The space station Spin Drift is being pulled towards a mysterious planet by a strange ruin. Piloting the super-robot Exector, you must save the ship. You have ten real-time hours to complete this mission. This mostly entails shooting enemy robots with a number of different weapons, and finding key cards to open doors. Weapons you can use include missiles, lasers, flame throwers, and the "Xector Genocide Gun".
