eShop: Touch Battle Tank 3D, $4.99
You are a tank, and your goal is to destroy all of the other tanks. Use the Circle Pad to move and the Touch Screen to aim, as you shoot your way through increasingly tough levels with more and more enemies each time.
DSiWare: Commando: Steel Disaster, $7.99/800 Nintendo Points
A military group is under attack by their own machines, due to a terrorist group headed by the evil Rattlesnake. You are the commando Storm, sent into each unit in order to stop the attacks in this action platformer.
Neo Geo: Real Bout Fatal Fury Special, 900 Nintendo Points
This sixth entry in the Fatal Fury series arrived in 1997 and introduced a two-line system of battle, and removed the possibility of ring-outs. The game has a roster of 19 characters, including four totally new faces to the series.
Digital releases are starting to drop off, probably in anticipation of retail releases. I hope they pick up again soon, or that New Super Mario Bros. 2 is astonishingly good.
