List of Wario Land 4 pre-release and unused content

These are the beta elements for Wario Land 4.

Beta Elements
The first screenshots of Wario Land 4 were revealed at E3 2001. They show several differences to the final game.

Charts
A difference seen in all of the gameplay screenshots is the Heart Gauge. It was shorter and had a garlic icon left to it, what implies that Wario originally had to collect garlics rather than little hearts to recover his Heart Meter. Furthermore, unfilled parts of the Heart Gauge were not segmented and filled parts appeared in green rather than red. Unlike in the final game, the Heart Gauge was also seen during boss fights. At least in the final version, little hearts don't appear during boss fights, making the Heart Gauge obsolete in those parts of the game.

The energy meter of bosses was different as well. While the meter's color changes depending on the boss's remaining hit points (high, middle or low) in the final version, it originally appeared in three different colors from the start, which labeled a high, middle and low amount of hit points each. The meter was also not generally segmented, but only the currently highest of its three differently colored parts. For example, if the boss still had a high amount of hit points, only the green part of its energy meter was segmented. Another difference is that a horizontal black line was in the center of the energy meter's unfilled parts.

Levels and Enemies
In the level Hotel Horror, the lights originally had no faces.

The Mayu Birds of the level Arabian Night had four fangs rather than two in the beta version.

The room of the first boss, Spoiled Rotten, did originally neither contain the TV set with the two Nintendo GameCubes nor the kitchen equipment in the background. Spoiled Rotten also had shorter teeth, no tongue and shorter leafs during his angry form. The white parts of his doll were yellow.

During the fight against the boss Cractus, the firefly already appeared at the beginning, while it is only seen in the final game when Wario has been turned into Zombie Wario. The two ladders in the room were not found, and plants of unknown purpose were hanging from the ceiling instead. The screenshot also doesn't show the timer. It did possibly not start until Wario cracked Cractus's plant pot. A more minor difference is that the ground of the room didn't have the indentations in its center like in the final version.
