Gamedaily writes: "THQ seems to have found a new niche with the Nintendo DS, first with Drawn to Life, and now with Lock's Quest. It isn't original, as it borrows heavily from Tower Defense, but its designers built upon that formula to make a nearly brilliant and most importantly fun portable game.
The gameplay seems simple enough: create defensive fortification, defend your location from assault and take on offensive objectives along the way. As the game wears on, and it lasts well over 20 hours, these encounters grow increasingly intense. The difficulty ramps up significantly if you play above Easy, and the artificial intelligence, a race of machines, is no slouch. Tapping for combat and construction has a slight learning curve, but it quickly becomes second nature and shouldn't hinder your desired speed in battle."
