Which Fortnite mode introduced in March 2022 removes building mechanics?

The Fortnite mode introduced in March 2022 that removes building mechanics is Zero Build.

Epic Games introduced Zero Build on March 29, 2022, during Chapter 3, Season 2. Instead of collecting materials and constructing ramps, walls, and forts, players must rely on weapons, movement, positioning, and the terrain already present on the island. The mode also introduced a regenerating Overshield, giving players extra protection before their regular health and shields are affected.

Zero Build was initially presented as a limited change to Battle Royale, but it became a permanent standalone option in April 2022. It is separate from Creative, where players construct custom islands, and from Battle Lab, an older sandbox-style Battle Royale mode. Ranked is a competitive ruleset that can apply to different Fortnite experiences, not the name of the no-building mode itself.
