The listing, Deadlings: Rotten Edition(steam key) has ended.
Death is lonely. He has zero friends on his FaceTome account and no one to hang out with. So, in order to feel better he begins “Project Deadlings”. Death buys a factory where he can build his laboratory and begin training a massive army of zombie minions.
As the army of Deadlings grows, the mazes of the laboratory become deadlier, loaded with puzzles and death-defying traps. Different Deadlings have their own unique abilities: Bonesack is agile - he can run and jump, Creep can climb on walls and ceilings, Lazybrain treads slowly but carefully and Stencher... well Stencher has gastric problems so he can use his powerful gas clouds to fly.
