It's a South Park double bill on this week's Xbox Live Deal of the Week as we get both the South Park Let's Go Tower Defense Play! arcade game and Lady Gaga Rock Band track for half off.

The kids of South Park have had video games of varying quality over the year but their first Xbox LIVE Arcade foray, South Park Let's Go Tower Defense Play! is one of their better efforts. The tower defense game featuring the four boys fighting off waves of zombies, hippies, ginger kids, and more is on sale this week for 400 MS Points ($5). Half off it's normal price of 800 MS Points ($10).
