1213 is a series of sci-fi adventure games by Ben "Yahzee" Croshaw. The games follow an amnesiac man only known by his subject number 1213. He is locked inside mysterious facility where his captor runs terrible experiments on him. Then, for reasons yet unknown, 1213 is freed from his cell, just to find out something has gone terribly wrong inside the facility.

Unlike previous games by Ben Croshaw, 1213 is an action-adventure game featuring Prince of Persia style platforming and 2D shooter mechanics.
