Infinity Danger and Little Racers: Street developer Milkstone Studios tackles the tower defense genre with its latest Xbox Live Indie Games release, Red Invasion.

Boasting some rather nice visuals, Red Invasion equips players with 8 tower types across 30 missions. One interesting feature: if being able to pan and zoom the 3D camera proves overwhelming for you, the game includes a "retro camera mode," which locks the view to an isometric perspective.

Red Invasion is priced at 80 Microsoft points ($1).
