If you’ve not heard of the game yet, here’s the lowdown:

A new original adventure title for the DS, Lock’s Quest will see players assume the role of young hero Lock as he defends his homeland from the imminent attack of robotic invaders. As an Archineer—part architect, part engineer—Lock uses his skills to build new structures around the sacred Source Artifacts with the ultimate goal of protecting them from infiltrators. Players can utilize different materials such as stone, metal, or wood to create and design defense towers in the battle field. There are also quirky weapons such as quicksand traps and glue cannons that the player can use to attack enemies.

Lock’s Quest combines the action/adventure and life simulation genres in a fast-paced broadly appealing game consisting of successive waves of building and battling. Elements of strategy and puzzle-solving are also incorporated to reward more sophisticated players, and players will be able to battle with friends through multi-card play or WiFi.

Action, RTS, and Adventure fans will all find something to like here.

The game is being developed by 5th Cell, the creators of Drawn to Life.

Certainly one to watch out for. Check back here for any announcements.
