Browser-based multiplayer arena
BWORM is a free online multiplayer worm arena built for the browser. Enter a living map, collect food, grow from a small creature into a dominant presence, and survive encounters where positioning matters as much as speed.
Enter the arenaWhat is BWORM?
BWORM combines the immediate readability of an online worm arena with distinct organic species, strategic mutations and an environment that visibly reacts to movement. It runs directly in a modern web browser, with no installation required.
How the game works
Collect food distributed across the arena to increase score, body length and presence on the map.
Steer through crowded routes, use boost when the opening matters, and manage the mass cost attached to acceleration.
Avoid exposing the head, use the body to influence routes, and turn positioning into pressure against other players.
Growth and survival move players through the live ranking while larger bodies create new tactical risks.
Ten enabled species use distinct anatomy, materials, silhouettes and boost identities rather than simple palette swaps.
BWORM is structured as a multiplayer arena where movement, growth and competitive state are governed by the game systems.
Combat Mode · Beta
Combat Mode is BWORM’s alternate ruleset. Each worm’s armor is divided into damageable zones: a hit damages the contacted armor zone first, and once that zone breaks, later hits can reach the body beneath it. The mode has six enabled loadouts, each pairing armor with a distinct weapon type.
Laser weapon.
Thermal weapon.
Plasma weapon.
Bioelectric weapon.
Railgun.
Physical spine bursts.
Mutations
Mutations change concrete attributes such as boost speed and cost, collection range, body width, zone pressure, collision control and braking. Each archetype supports a different way to approach the arena.
Built for pursuit, marked targets and rewards that chain one elimination into the next.
Prioritizes mass, collection reach, body presence and growth advantages tied to ranking.
Applies visible proximity pressure, slows nearby rivals and rewards controlled near-collision play.
Reduces mobility costs and strengthens escape tools, trading direct offensive presence for survival.
The map
The map is authored in world space, so exploration reveals different regions instead of moving a decorative backdrop with the camera.
The arena is open
Choose a species, enter the map and discover which movement and mutation strategy fits the way you play.
