Nintendo Power was so fast on the draw when revealing "Lock Nation" that the game didn't even have its final name yet. That sort of works to IGN's benefit -- since, while Nintendo Power got to exclusively unveil "Lock Nation," IGN gets their own exclusive on Construction Combat: Lock's Quest. Even though it's the same game.
Along with news of the rechristening, IGN posted really nice screens of the tower-defense/RTS-esque game -- the distinctive Drawn to Life look is clearly on display here. They included a bit more about gameplay, as well. For example, the materials you can collect include metal, stone, and wood, and combine in different amounts to form the various available structures and defenses.
