Two very interesting games are Free on Steam starting Friday, August 19 as part of another Steam free weekend event. One of them takes place in space and the other underwater.
If you wanna take a break from No Man’s Sky, you can check out Eve Online. It’s a space MMO with nice visuals. The second is Depth, an underwater game where you can play as a diver or as one of many kinds of sharks.
You can download them and play them for as long as you wish, starting this Friday, August 19 until Sunday, August 21.
