Today's Steam special is Brendon Chung's turn-based strategy game Flotilla, which is currently on sale for only $2.50 (75% off the original $10 price). A demo for the game is available from Steam and the official site, where you can test out both single and two-player modes before deciding on a purchase.

Flotilla was one of our top ten Xbox Live Indie Game picks for 2010 as well, but it's going to cost you 400 MS points ($5) to purchase it for your Xbox360 console. This Steam offer is valid for one day only, so if you were on the fence about grabbing it earlier then this promotion should sway you over.
