In honour of Bungie Day, Destiny fan Brenton Whitwell made a sidescroller version of the vast online shooter. In honour of Destiny, it has no story. Whitwell's sidescroller -- which he called Project Tiger, after Destiny's original codename -- is short but surprisingly fun, letting you gun down some shanks and hop around a 2D version of the Cosmodrome. Props if you can beat Sepiks Prime without dying.
Check out Whitwell's Reddit post for links to download the game on PC and Mac, or just watch him play through it here:
