Assassin's Creed: Origins lands one month from today, bringing with it puzzle-filled pyramids, Witcher-like investigation, and Caesar and Cleopatra. Expect new words on that from our Tom over the next few days. If you're yet to sample what's come thus far, though, the Assassin's Creed series is on sale now through Friday on Steam. 

Despite their age, that means netting both Assassin's Creed and Assassin's Creed 2 for just £2.71/$3.39 with a 66 percent discount, and Assassin's Creed Revelations for £4.07/$6.79. 2014's Liberation and the standalone Freedom Cry are going for £5.43/$6.79 and £4.07/$5.09 respectively, while the Climax Studio-led China Chronicles spin-off is just £2.71/$3.39.
