Recipient of the IGF Design Innovation and Technical Excellence Awards, World of Goo is a physics-based puzzle/construction game made entirely by two guys working out of coffee shops in San Francisco. You may drag and drop living, squirming, talking, globs of goo to build structures, bridges, cannonballs, zeppelins, and giant tongues. The millions of Goo Balls that live in the beautiful World of Goo are curious to explore - but they don't know that they are in a game, or that they are extremely delicious.

Once World Of Goo, the current free game on the Epic Games Store, has run its course it will be up to Stories Untold, which will gratis starting on May 16 until May 30, 2019.

Stories Untold is a narrative-driven experimental adventure game, that bends the genre into something completely unique. Combining a mix of classic text-adventure, point-and-click and more, 4 short stories are packaged together into a single mysterious anthology that has been described as “a fantastic, fascinating example of interactive visual storytelling” and earning widespread critical acclaim since release.

The game pulls together 80s retro nostalgia, innovative and experimental genre-defying gameplay, and tense, psychological horror to create one of the most fascinating and unique tales you can play.
