Microsoft is currently offering excellent discounts on eighteen Xbox Live Arcade titles including Trials HD, Outland and Shank. Most of the games are discounted by 50%, although there are one or two exceptions. These special offers are valid until next Monday, October 3rd.

I’ve flipped through the North American, European and South African marketplaces, and can confirm that the specials apply to all these regions. However, some of the featured XBLA titles such as Outland are not yet available from the South African marketplace, so expect a smaller selection of discounted games to choose from if you’re using a SA account.

The full list of XBLA titles currently on special are as follows:

• Serious Sam HD: The First Encounter - 400 Microsoft Points (usual price = 1200 MSP)
• Outland - 400 (800)
• Yar’s Revenge - 400 (800)
• Islands of Wafku - 400 (800)
• Trouble Witches Neo - 400 (800)
• Bionic Commando: Rearmed - 400 (800)
