About game:
Junk, junk and even more junk. Life on the trash-planet Deponia is anything but a walk in the park. No surprise that Rufus had enough of that and hatches one ludicrous plan after the other to escape this bleak place.
When Rufus, on one of his attempts to leave Deponia behind, meets Goal, he not only falls madly in love with the beautiful girl from Elysium; he also accidentally shoves her right off her comfortable star cruiser and down to the desolate trash-planet. This accident kindles a new, brilliant plan: he needs to get Goal back to the floating city of Elysium – and while he's on it, he can also impersonate her sleazy fiance Cletus, who is the spitting image of Rufus for some reason. And thus, an exciting adventure begins...
