Bowser's Tank Terror

Bowser's Tank Terror is the final boss minigame appearing in Mario Party 10. It takes place in Chaos Castle and pits players against Bowser.

Introduction
The minigame takes place in a volcanic landscape, in the middle of a sea of lava. The players are shown piloting small tanks on a square arena resembling a small castle. The camera focuses on the center of the arena as Bowser is lifted in by an elevator, piloting a large purple tank with five cannons. After laughing at the players, he sits at the controls and roars, beginning the minigame.

Gameplay
Unlike in most boss minigames, the gameplay changes drastically between phases.

Phase 1
Initially, players must fire bombs at Bowser's tank, gaining one point per hit. Mushrooms in bubbles periodically float into the arena; touching one enlarges the player, doubling their damage but slowing their speed. If hit while giant, the player shrinks back to normal; if hit at normal size, the player bounces off Bowser's tank (if they hit his tank with their tank).

Bowser mainly attacks by firing spiked bombs from his tank's main cannon, but he can also launch flame jets from the four cannons on the corners of the vehicle&mdash;at this point, he usually rotates in place to try to catch players offguard. Being hit by any of Bowser's attacks deducts two points from the player's total. Touching Bowser's tank does no damage, but it can still shrink a giant player.

As Bowser takes damage, his tank begins losing parts of its armor, including its side cannons (disabling one of his flame jets). When his health approaches the halfway point, Bowser begins using a charge attack that takes away two points from any player it hits.

When Bowser loses half of his health, his tank explodes and hurls him into the lava north of the arena. However, he quickly returns as Dry Bowser, enlarging himself and destroying the outer edges of the arena with a monstrous roar.

Phase 2
Now on a smaller, rectangular arena, players must continue to fire at Dry Bowser to earn points and deplete his health. Mushrooms still spawn periodically, enabling players to double their damage output until they get hit.

Dry Bowser mainly attacks by breathing large blue fireballs or throwing bones across the stage. He can also jump into the background (out of the range of the players' cannons) and bombard the stage with fireballs; players should watch for the blue spots and move to another part of the stage. All of Dry Bowser's attacks take three points from anyone they hit; his fireballs can redirect the movement of Mushrooms that touch them, but his bone attack knocks them out of the arena.

Bowser has 286 hit points in total, across both phases. The player who lands the finishing blow gets ten extra points before the result screen is shown. The player with the most points overall wins the minigame.

Ending
After gaining the last hit, Dry Bowser glows brightly while clutching his stomach in pain before exploding.
