A game called Humankind, which is a paid game originally, is giving away closed beta Steam keys. The giveaway expires on the 21st June.
It kind of looks like the Sid Meir’s Civlilzation franchise.
HUMANKIND™ is Amplitude Studios’ magnum opus, a Historical Strategy game where YOU will re-write the entire narrative of humankind – a convergence of culture, history, and values that allows you to create a civilization that is as unique as you are. HOW FAR WILL YOU PUSH HUMANKIND?
