Valve have knocked 75% off the cost of Arkham Asylum and Arkham City on their Steam service, meaning the pair can now be bought together for a total of £7.49 (or separate for £2.49 and £5). The offer is part of their midweek madness sale, meaning you only have a few days to take advantage of the deal before it expires, so if youre one of those weirdos yet to play these masterpieces you need to act quick and buy them now! The version of Arkham City in question is the Game of The Year Edition, so along with the full main-game youll get all the additional DLC too, including Harley Quinns Revenge, Catwomans story missions, seven extra challenge maps, 12 additional costumes, and both Nightwing and Robin as playable characters. That means theres well over 40 hours of gameplay available in City alone, while the £2.49 GoTY edition of Asylum offering roughly another 12 to 14 hours if youre looking to buy the pair. Arkham Origins is set to come out later this year and will concentrate on events that prelude the two previous games, focusing on eight assassins coming together under the employment of Black Mask in an attempt to kill the Dark Knight. This recent Steam sale may have been orchestrated to increase the fanbase for the upcoming title and help Valve make profit through sales in the long run, but whatever the reasoning its still a great deal and youd have to be a fool not to take advantage of it.
