One of today's pressing problems here, namely what do the next fifty generations of humanity do with all the canned Roentgens from Windscale/Sellafield and the like? CCS come up with a charmingly lo-tech solution: drop 'em all down a hole in the ground, and head-butt them in the right direction.
The main movement is left-right to get under the falling drums to redirect them into the right channels. If too many waste cans gather in the 'illegal' slots than it's melt-down time. It has a certain charm, but the graphics are very basic, and I wasn't hooked.
