Deponia Doomsday

The flying city of Elysium has fallen, hideous Fewlocks inhabit the junk planet Deponia and Rufus is apparently the sole (human) survivor. He sees only one way out: Deponia must be blown up.

Terrified, Rufus awakes in his bed. Was that a dream or a vision? Fortunately, Rufus can check this right away as the oddball Professor McChronicle has detected several time anomalies. It's rather handy that Rufus finds a time machine and immediately sets out to duly muddle up the past, present and future.
