Deponia
Rufus is not a pleasant guy. Ill-tempered and entirely too convinced of his own greatness, he lives at the edge of a small settlement somewhere in the most remote sector of the garbage-covered planet Deponia. He dreams of a better life in the floating cities of wealth and beauty high above the planet surface. When the angelic Goal falls from these privileged spheres down into a neighboring trash heap, Rufus sees his chance. He decides to bring the unconscious beauty back to her home. Only a vague hope of making it off Deponia at first, he soon formulates an unscrupulous plan, as he learns that he is a dead ringer for Goal’s upper-class husband. The planned handover is only the beginning of a wild chase across Deponia full of twists, turns and mystifying mix-ups. Deponia is a fast-paced comedy of errors and one of the most unusual love stories in gaming history. The twist-filled story takes its off-beat characters all over trash planet Deponia, a unique game world in the style of Douglas Adams, Terry Pratchett and Matt Groening. From Kuvaq, an improvised village built inside a giant trash heap, to the swimming black market and the dark corners of the elevated planetary railways: The new adventure game from the makers of The Whispered World, Edna & Harvey: The Breakout and A New Beginning is brought to life with detailed hand-painted backgrounds in widescreen format and top-quality cartoon animation. div.game_top { height:312px; } ul.labels > .lang_bubble { margin-bottom: 20px;} ul.details > .lang_details { height: 30px; line-height:16px; max-width:360px; padding-top:1px;} Unique comic style with hand-drawn HD resolution 2D graphics.
