Alan Wake and For Honor are both free on the Epic Games store.
Alan Wake, the action adventure game developed by Remedy, is free on Epic's store until 9th August.
For Honor, Ubisoft's melee multiplayer-focused action game, is also free on Epic's store until 9th August.
It's worth noting the free version of For Honor on the Epic Games store is the standard edition, which means you get everything in the base game.
Both games are absolutely worth a shot, if you haven't played them already. Alan Wake is a spooky story-driven game that finds Remedy in quintessential form, while For Honor is in a good place now after a rocky launch.
