This Week on Xbox Live Arcade: Yo-Ho Kablammo, Defense Grid

Canalside's piratical action game Yo-Ho Kablammo and Hidden Path's strategy effort Defense Grid are this week's two Xbox Live Arcade releases, Microsoft has affirmed.

Yo-Ho Kablammo sees players blast foes with cannons and other power-ups across its single-player and multiplayer (both online and off) modes in an attempt to rule the seas. nope

Defense Grid: The Awakening, meanwhile, has players strategically building and upgrading defenses to hold off ever-increasing waves of invading enemies. The Xbox 360 edition packs all of the content found in the PC release, plus a few new levels.

Both Xbox 360 downloads are due Wednesday, Sept. 2, at 800 MS Points ($10) a pop.
