Abandon Complete is a special edition of the game released in 2009, including 50 entirely new levels. In the original version all creatures had the same behavior. They simply chased you. In Abandon Complete there are several different types of creatures, each with a different type of behavior. Some creatures now help you, some toy with you, some try to confuse you. Abandon Complete is a much more fleshed-out version of the original game, one that requires more complex thinking to master. Watch out for the toaster!

Abandon showcases a large array of animated objects. The development team utilized experimental, automated rigging software to enable rapid creation of animated models. The direction for the project was motivated by the desire to create a game featuring a large number of unique animated models, not normally feasible with a small team size and short development time frame. The team strived to create a world for the player where just about anything can come to life.
