The only good robot is a dead robot, and make the most of it because you can be sure as hell that the Commission for Robot Equality is only a spit into the future. Which brings us to Renegade Robots. This is a bit like a giant sliding block puzzle, added aggro coming by way of the now familiar group of vicious robots.
OK. The planet is under dire threat of invasion, but fear not, scientists have everything under control. Or they did have until a series of explosions wrecked the production of the secret weapon they were working on. Amongst other things the explosions caused the robots manning the production line to go berserk. The only way to save the line is by aligning three key control cubes or destroying the renegade robots. Moving blocks means getting behind them, gritting your teeth and shoving like hell, whereupon the block careers across the screen, junking anything in a straight line between here and eternity. You know the Pongo lick.
Once the robots are sorted out, some idiot scientist makes the same mistake and you have to start all over again. A robo-hunter's job is never done.
