Microsoft wants to pay you $10 for purchasing all five of the games showcased in this year's Summer of Arcade promotion.
U.S. Xbox 360 owners who shell out the 5600 Microsoft Points necessary to net them Splosion Man, Marvel Vs. Capcom 2, Turtles in Time Re-shelled, Trials HD, and Shadow Complex between now and August 31st will get an extra 800 Microsoft points added to their account, basically cancelling out the price of Splosion Man. From a monetary standpoint, it amounts to getting $80 worth of Microsoft points for $70, which is a pretty good deal no matter how you look at it. Of course, if you don't buy all five games you get nothing, but that's the price you pay for not paying the price for everything.
