OverKill is a fast-action arcade game. You arrive at your home planet after a long space flight, only to find it has been destroyed by a demonic warlike alien race that kills for sheer pleasure. You are now the last of your race and out for revenge.

Your single minded quest is to destroy the alien leader's heavily armoured Battle Star at the end of planet 6. But before you reach the Battle Star you will have to battle your way through massive levels packed with danger, freeing six other planets from the tyranny of these creatures.

Some of the dangers you will face include meteor storms, space forts, hideous creatures and strange space ships of incredible power, piloted by aliens who will do anything to stop you.

Although you have limited fuel and weapons supplies, both can be collected on your long and perilous journey by picking up pods from the remains of alien crafts and creatures you have killed before reaching your ultimate goal.

If you are lucky you will have collected enough pods to have built the ultimate battle cruiser, a craft of immense fire power and capable of mass destruction, yet even this craft may not be enough when you reach the final battle ground.
