"1213" is a trilogy of horror science-fiction games. The episodes tell the story of the suffering and eventual escape of an amnesiac victim of experimentation, code-named 1213, from his cell, freed by his unseen tormentor. On escaping, 1213 sees that the facility's other guinea pigs, all similarly named to himself, have also escaped and have been turned into zombies, slaughtering the employees. "1213" is notable for reproducing the traditional platformer experience using an engine originally designed to be used in the production of point-and-click adventure games. Simply animated, many elements of the game reflect the original "Prince of Persia" gameplay mechanics, though it incorporates aspects of gunplay found in "Another World" and "", the latter of which he has written a sixteen-chapter Let's Play of.
