The original developers of The Binding of Isaac are working on building an online multiplayer version of the legendary roguelike, but testing has been stalled after players hacked their way into unfinished modes.
In a recent tweet (via Roguelikers) executive producer Tyrone Rodriguez said that alpha tests of the 'Isaac Online' had been taken offline because "someone took it upon themselves to hack the online version to play other modes." Each month, testers had the opportunity to play the game, including a rotating game mode. In this instance, however, the hacker got around the current mode, "and shared how to do this hack with other players."
