This week Epic Games is giving away the cyberpunk horror game Observer (> observer_ in the original spelling) and the action thriller Alan Wake's: American Nightmare until October 24th. In the coming week, there is the cube-based puzzle game Q.U.B.E. 2 and Layers of Fear from the horror genre for free.
Observer lets players as members of the “Neural Police” investigate events in a foreclosed block of flats by hacking into objects and the implants of the deceased. The action-thriller Alan Wake's: American Nightmare is a more action-packed spin-off of the original, forcing Mr. Scratch into an episode of a fictional TV show in a horror world to fight the “Dark Messenger” ,
Both games can be obtained via the promotion page in the Epic Games Store. This requires an account with the provider and the use of the shop client, which is required for the download and game start.
