Claim your free copy of Limbo by June 22
Steam often has free weekend events where players can try out a game for free over the course of a few days. It's not typically used to outright give games away, but that's the case right now with Limbo.

Much as it did recently on Xbox One, Playdead is giving away Limbo through Steam. This is the full game you can add to your account and keep forever, no strings attached. You can claim it by heading to Steam either today, June 21, or tomorrow, June 22.

This freebie comes just prior to the release of Playdead's new game, Inside. It's set for launch on Xbox One on June 29, with a PC release coming on July 7. Much like Limbo, it's an atmospheric platformer starring a young boy, albeit one that's arguably a bit less visually distinctive--which is no slight, given Limbo is one of the most memorable-looking games ever.
