Three Xbox Live Arcade titles received a permanent price reduction this month. Players can now get Penny Arcade Episode 1, Penny Arcade Episode 2, or Lode Runner for 800MSP. They join Hydrophobia as recent XBLA price reductions. Several other bits of marketplace content have received a price cut, including some downloadable content and Games on Demand. Check the Sales & Specials section of the Spotlight channel for additional discounts. Also note that the title of the price reduction section states “This Month”, possibly indicating that price cuts may happen on a monthly basis.
