Free Steam key for Life Is Strange - Episode 1 here:
https://store.na.square-enix-games.com/en_US/product/282531/life-is-strange-episode-1-steam

Note: the game is already free on Steam itself; however, it's only a free-to-play license. By getting it from Square Enix, you get the retail license - basically the same game, but it gives +1 to your total games (which means more progress for the Games Collector badge).

Control, free on Epic until June 17th

@ DanelSonic123: My instruction post probably wasn´t the best written one, but almost everyone understands what I wanted to say. Suggestions for improvement are welcome.
The only exception was for the Half Life Series. Every Half Life Game was time limited Free2Play for around 5 months I guess.

Yoku's Island Express - for free on EPIC GAMES.

Actually I got a thought I want to share: Is this thread the cause for all this trouble with the spammers?
The game names/game links are, especially in the time-frame from when the games are free, somewhat a target for bots.
