Paradroid

The game is set on a spaceship viewed from a top-down perspective. The ship consists of numerous rooms and levels, each one populated by hostile robots or "droids". The player, in control of a special droid called the "Influence Device", must destroy all the other droids on the ship.

Each droid (including the player) is represented as a circle around a three-digit number. The numbers roughly correspond to the droid's "power" or "level", in that higher-numbered droids are tougher to destroy.
