List of Wario Land 4 pre-release and unused content

This is a list of beta elements for the game Wario Land 4.

E3 2001
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 next 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 its angry form. The white parts of its doll were yellow.
 * During the fight against the boss Cractus, Hotaru 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 screen-shot 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.

Unused Data
A small room was removed from the end of the level Palm Tree Paradise. It would have been accessable by ramming the wall behind the Frog Switch. The room itself has programmed sprite layouts for each game mode. Normal mode includes a single Totsumen with a Diamond at the end. The number of enemies increases to five on S-hard mode, and the Giant Diamond is removed.

Debug Level
Before creating full levels, the game's developers prepared a simple debug level with lots of different obstacles. This area allowed them to test Wario's moves and abilities as they were programmed, to prevent future problems with gameplay. The level itself is quite simple in design, with a blue background, and black blocks with dotted outlines for flooring. Several slopes, blocks of varying sizes, coins and enemies are found throughout the level. Wire mesh can be seen in some rooms as part of the background. Many Doors are also included to move between different rooms.

Music
In the last level, Golden Passage, the player inevitably lands on the Frog Switch upon entering the level, regardless of the Game Mode. So in result, the Frog Switch music plays throughout the whole level. But, if the player uses a hacking device such as an Action Replay, to avoid stepping on the Frog Switch, a hidden soundtrack plays, which can not be heard in normal gameplay. During game development, the Frog Switch was placed towards the end of the level, and was originally going to be placed at the beginning only for the "Hard" and "S-Hard" game modes.
