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 "Exector Genocide Gun".
The gameplay is fast-paced and action-packed, requiring quick reflexes and strategic thinking to overcome obstacles. You'll need to scavenge for ammo and upgrade your arsenal as you progress through levels, all while managing your time to avoid being caught in enemy fire.
