W: A features a variety of gameplay modes. In the classic solo campaign mode, the player must lead their team through a series of battles, carrying out different objectives along the way. In multiplayer mode, the players take on each other locally or online. Multiplayer mode features a high level of customizability, with the player able to adjust health, weapon sets, and other aspects of the gameplay. The player can also create their custom terrain maps by using a terrain editor or importing picture-format maps, which are converted automatically into the game arenas.
