Grab a cheap copy of the Batman: Arkham Trilogy for just £10 on PS3 or PC.
Time is a slippery bastard, so we understand that for some reason or another, some of you just might not have played the excellent modern Batman Arkham series yet. Don't worry, we forgive you, but if we're going to carry on being friends, you should sort this out by picking up the Arkham Trilogy for just £10 on PS3 or PC. It includes Arkham Asylum, Arkham City and Arkham Origins.
