The entirety ofThe Callisto Protocolhas now been leaked via a series of several-hours-long Twitch streams posted one after another. The single-player horror title is due to launch in just a few days' time, on December 2, but the leaks mean that anyone that’s really curious about the game’s story or gameplay now has a way of seeing just about everything there is to see, with spoilers being an obvious concern.
Namely,The Callisto Protocolis a spiritual successor to the oldDead Spacegames, and its production has been headed by Glen Schofield himself, who was responsible for the creation of the original franchise in the first place.
