Verum Rex: Beat of Lead

Verum Rex: Beat of Lead is a Mini-game that appears in Kingdom Hearts III. It is first played when entering the Video Game store in Toy Box, and can be played at any time after being initially completed.

Story
Beat of Lead is a demo for Verum Rex on display at Galaxy Toys' third-floor video game store. Rex comes to the store in pursuit of a Verum Rex strategy guide, causing Sora, Donald, Goofy, Woody, and Buzz to collect him when preparing to leave. While there, Young Xehanort has a Marionette possess Buzz in order to test the bonds of the toys' hearts; when Sora attempts to intervene, Young Xehanort blasts him towards the display console, teleporting him into the demo. After completing the demo, Sora is freed from the console.

Mechanics
The objective of the demo is to defeat Gigas enemies in order to rack up points. Defeating Gigas in a string will provide a score multiplier; defeating Gigas via the use of various traps will provide bonus points. After a certain threshold of enemies defeated is cleared, Ace Gigas begin to appear, worth bonuses. The final boss is the Hyper Ace Gigas, whose appearance after a certain threshold causes the rest of the Gigas to disappear; defeating the Hyper Ace Gigas will clear the demo.

Sora begins next to an unpiloted Speed Class Gigas which he can mount immediately. Once an enemy Gigas is defeated, Sora can eject from his Gigas to mount it. Little Ace Gigas cannot be mounted; as the demo ends once the Hyper Ace Gigas is defeated, it too cannot be mounted. Ace Gigas maintain their higher damage output when mounted by Sora. If Sora chooses not to mount a Gigas, he can fight enemy Gigas with his Keyblade as per normal gameplay; however, Sora is limited to his Kingdom Key and cannot change weapons, regardless of his equipment options beforehand. Second Form and Rage Form are available as usual.
