In addition to the two free weekends that are now in progress, you will be able to get two more games permanently in the next few days.
The first is Bad North, available on the Epic Games Store. Bad North is a strategy game in which you must defend an island from an invasion of Vikings, who came to do what any viking would do, to viking. The game is available until next Thursday, when it will be replaced by Rayman Legends. For those who don’t know, Rayman Legends is one of the best platformers ever made.
Humble Bundle does not offer Serial Cleaner. A game similar to Viscera Cleanup Detail, but with a purpose. You have to make sure that there is little evidence that something unclean happened at the scene of a crime … more than one crime. This is probably what happens after a level in Hotline Miami. This game is only available for two days, and only if you subscribe to the Humble Bundle newsletter, so you should hurry up.
