Xbox One with Assassin's Creed: Unity and Black Flag can still be had for just £299.99 at Argos. Click here to buy >>
Like your Assassin's Creed? Well, you'll get a kick out of this. Depending on who you talk to, it looks like Ubisoft might have finally ironed out all of the creases in Unity, though they probably haven't fixed the feature bloat, Uplay integration, or borked mechanics.
Do be aware that for £50 more at GAME, you can get this plus Kinect, Forza 5 GOTY, and LEGO Marvel Super Heroes. Cheers Buzz and Rubs!
