VS. Wrecking Crew

VS. Wrecking Crew is a 1984 arcade game for the VS. System, predating the 1985 console game Wrecking Crew. The game is less puzzle oriented, does not contain the level editor, and features a simultaneous two-player mode in which the opposing player is seen on the other side of the construction wall. In single player, Luigi acts similar to Foreman Spike and is present in all levels, while Foreman Spike is absent entirely.

Gameplay
Unlike Wrecking Crew, the screen does not scroll vertically, and the gameplay takes place on a single screen. Besides this and Luigi acting as Foreman Spike in all levels, the single player is mostly the same.

However, the game was designed specifically for the VS. DualSystem, and thus featured innovative mechanics only possible with multiple screens. On each screen, each player will see the enemies that can harm him as red, while the ones dangerous to his opponent as blue. If an enemy walks into a door (which are opened the same as the NES version, by swinging at them), they will switch the side of the playfield that they are on. This allows both players to compete by luring enemies on their opponents side, while simultaneously competing for score by demolishing as much of the building as possible. If both players are at the same wall piece, whichever swings first will knock the other down to the bottom of the playfield, as can be done with enemies that are on the other side compared to where the player is.

While a lot of this is possible in single player, Luigi is much less aggressive than an actual second player would most likely be and thus a lot of what can happen in multiplayer will not in single player.

Trivia

 * Japanese flyers depict Mario and Luigi without mustaches, which may be a holdover from an earlier period of development when they were not the main characters.
