Pre-Christmas giving away free games does not end and after the great Shadow Tactics, Godfall, Prison Architect and Call of Juarez: Gunslinger, this week you can enrich your virtual bookshelves with the excellent jumping game Rayman Origins. Despite the fact that this year it has celebrated 10 years since its release, it is still the top of the genre, which you can also enjoy in cooperation with up to three other players (see our review). Everything you need can be found at this link.
