Lock's Quest

Lock, his new friend Isaiah, and Lock's grandfather Tobias set out in search for Emi.

Along the way, Lock joins the Archineers and Kingdom Force in hopes of defeating the Clockwork army and their leader Lord Agony.

The gameplay consists of two main modes of play: "Build Mode" and "Battle Mode." In Build Mode, the player has a limited amount of time to build defenses that will stand up against the approaching Clockwork army.

Each defensive object costs a certain amount of "Source" (the game's currency).

Many levels have protection objectives that the player must defend and prevent from being destroyed by the Clockwork.

The player can build walls and gates of various material types (Wood, Stone, Metal and Spiked), unique "Turrets" that automatically fire at approaching enemies, "Traps" that can be placed in the battlefield and stationary "Helpers" that give nearby turrets specific buffs.

Each player can develop a personal strategy that best fits his play-style based off of the current terrain and his choice of defences.

New abilities, enemies and areas are constantly unlocked as the player progresses through the entire game.

Battle Mode begins when the Build Mode timer runs out, or when the player chooses to advance to the battle.

The player is thrown into a real time battle and must defend the protection objectives for a certain amount of time while holding off the attack.

Other objectives include: destroying specific groups of enemies, capturing enemy objectives, rescuing friendly characters and destroying boss enemies.

The battles involve controlling Lock directly with the Stylus as the enemies attack.

The player may engage the Clockwork enemies in mêlée c

Lock's Quest for Nintendo DS is currently worth €13.03 loose, €8.50 complete in box, and €16.14 factory sealed. Prices are based on real sales and update regularly on Gamevaro.

Lock's Quest has a steady sales history on the tracked marketplaces, meaning it trades hands regularly and isn't considered particularly rare.

Loose means cartridge or disc only, CIB (complete in box) includes the original box and manual, and sealed means factory-sealed and never opened. For Lock's Quest, loose is €13.03 and CIB is €8.50 — CIB commands a premium because original boxes and manuals are fragile and often don't survive.

The PAL version of Lock's Quest is currently worth €13.03 loose, versus €11.14 for NTSC-U. Regional price differences usually come down to print run size and regional collector demand.
