A demo of 5th Cell's tower defence game Lock's Quest is now available from the European Nintendo Channel.

Nintendo of Europe have released the second Nintendo DS demo for the Nintendo Channel in the space of a week in the form of Lock's Quest, from the creators of Drawn To Life for the DS.

Lock's Quest is a tower defence game from 5th Cell which sees you as the young mechanic Lock on a mission to rid your homeland of a horde of robotic invaders. Build, strategise and fight your way to victory, and harvest scraps from your fallen enemies to rebuild your defences and create new weapons in the fight against evil.

The demo of Ninja Gaiden: Dragon Sword has been removed, but you can still grab the Doodle Hex demo, a rather lacking taster of Spore Creatures and a host of Nintendo demos, including the brilliant 42 All-Time Classics and Picross DS.

Lock's Quest is out now for the Nintendo DS in Europe.
