Build 'n Bump

Build the level, then battle your friends! Head-stomp your way to victory in this fast-paced local multiplayer party platformer.

Build it. Bump it.

Inspired by the cult-classic Jump 'n Bump, Build 'n Bump adds a creative twist: before you fight, you build the battlefield.

Up to 6 players can duke it out in fully customizable arenas. Stomp on heads to score points, avoid traps, and knock your friends into pixelated chaos. Use five unique block types to shape the arena before each round, or try Level Master Mode, where one player edits the map in real time while the match is happening.

Gameplay Highlights

Note on Online Play


Online mode supports only one connection between two computers via direct IP. Familiarity with port forwarding is required. There are no dedicated servers or public lobbies, but Steam Remote Play Together is a great alternative for most players.
