This is yet another of those games where you wander from room to room blasting robots.
The aim of the game varies according to which level you find yourself on. As you enter a level, the program sets you a task, which involves finding an object or objects and then finding a safe to put them in. There is a silent game option, and a pause key. The choice of control keys is sensible and doesn't hinder you as you blast Spinners. Clones, and Cyber-droids.
The graphics aren't wildly exciting, but the rooms are numerous and the robots obligingly suicidal. Addicted mega-zappers could do worse.
