And now for something different: this week's Live Arcade release, Band of Bugs, is a turn-based tactical strategy game. Think Final Fantasy Tactics or Front Mission but replace the knights and giant robots with grasshoppers and beetles. Here's a video that shows the game and the included level editor (!) in action:
In addition to a single-player campaign Band of Bugs also features multiplayer for up to four people locally or over Live — and you can even take your custom maps online. All for the low-low-price of 800 Microsoft SpaceBucks.
