Ironically, the two Bionic Commando Rearmed games leap off the list initially; the first going for 320 MSP, the second for 480 MSP. Then we see that Grasshopper/Digital Reality collaboration Black Knight Sword is slashed in half to 400 MSP, while the savings cut even deeper for Hell Yeah! - it's down to 480 MSP from 1200 MSP, the exact same discount for Ubisoft's urban survivor I Am Alive.
There are also savings to be made on Gotham City Impostors, Warhammer 40K: Kill Team, Lara Croft: Guardian of Light, and stalwart of the XBLM deal circuit Geometry Wars: Retro Evolved 2. Of course, if you haven't yet bought the excellent Retro Evolved 2, then we will be forced to slap you. We're sorry, but them's the rules.
