Lock's Quest

Background

In Construction Combat: Lock's Quest, players create a virtual world block-by-block to defend their homeland against invading enemies. With the innovative use of the Nintendo DS stylus, players will be able to immerse themselves into the building and creating process.
You 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.
