You are a Runner who is trying to steal chests stuffed with gold. The Guards, dead-hearted robots that can catch and kill, are trying to stop you. The trouble is that you are almost unarmed. There is no use shooting, regular weapon doesn't work on robots. You can't even jump — the weight of the gold already collected presses you down on the ground.

Even though, you are lucky. In an abandoned laboratory, you have found something like a rock laser, a tricky jackhammer that can punch holes in the brick floor. The thing is strong, but it doesn’t work on robots straight away. However any mechanism can be used as a weapon. You can punch a hole in the floor right in front of the robot and it falls down there. After a while, the hole in the floor closes, and its brittle walls collapse. The robot gets immured and goes to the Devil, if by this time it doesn’t gather its wits to get out of the hole. Don't celebrate too early – the comrades of the immured call for help and drop the new robot from the air. But you have time to finish all your business — collect all the chests of gold in the room and run up the emerged stairs.
