Layers of Fear: Masterpiece Edition and QUBE 2 are free for the taking until October 31, at which point they'll be replaced by Double Fine's Costume Quest and another horror game, SOMA.

Qube 2 is a sequel to the popular first-person puzzler which refines the core mechanics of the original. It also features a more tightly woven narrative that expands the Qube universe.

QUBE 10th Anniversary has been rebuilt from the ground up to give fans a new experience of the first person puzzler. The original QUBE was released back in 2012, with QUBE 2 following in 2018.

QUBE 2 is a first person puzzle game by developer Toxic Games, and it's a sequel to the well-received QUBE. Actually QUBE is spelled Q-U-B-E, which stands for Quick Understanding of Block Extrusion.

In our QUBE 2 review Adrian wrote: Thanks to its derivative nature, Q.U.B.E. 2 never quite escapes the shadow cast by Portal.

Watch on YouTube As for QUBE 2, it's a game I know significantly less about, so I'm afraid you're going to have to make do with a summary of its store page.
