We've already seen a number of tower defence games on the DSi, but there's always room for one more. A good job really, as next week sees the release of SteamWorld: Tower Defense from Swedish developers Image and Form.
Taking a steampunk-inspired approach to the genre, you're the role of Sheriff of the Cowbots, a robotic race that oversees the gold-rich SteamWorld. When humans begin to invade in search of lustrous ores, it's down to you and your defensive robots to keep the nuggets out of human hands.
With an intriguing graphical style and the promise of robots shooting humans, this could stand out in an increasingly crowded field on DSiWare. We'll bring you a full review shortly after the game's North American release next week, but fill your boots with this trailer in the meantime.
