Blob Siege

A free multiplayer voxel shooter that runs entirely in the browser. Two modes — Capture the Zone and Zombie Survival — with rooms for up to 5v5. Players connect directly to each other, so there is no server in the middle and no account to make.

How to start a match

  1. 1
    Host or join a room

    Hit Host a game to get a 5-letter room code, then share the invite link — friends who open it drop straight into your lobby. To join someone else, enter their code in the join box.

  2. 2
    Pick a side

    Capture the Zone splits the lobby into Red and Blue teams; you can switch sides from the lobby. Zombie Survival puts everyone on one team against the horde.

  3. 3
    Practice alone first

    The main menu has a Tutorial and a Practice alone option, plus leaderboards and a blob customizer — worth a run before jumping into a live room.

Connection note: rooms connect peer-to-peer, so most home networks work instantly. Some school, work and mobile networks block direct connections — if a room "could not be reached", that is why, not a dead link.

The two modes

Capture the Zone

Defenders build a fort around a flag while attackers vote on which side to push. Build a fort, blow it up, take the flag.

Zombie Survival

Everyone on one team against zombie waves that keep getting bigger — solo or co-op — with a Mystery Box, drones, pings and weather.

A different "Blob Siege"

Two unrelated browser games share this name. If you were looking for the co-op boss arena instead:

Blob Siege (blobsiege.world)

A 2-player couch arena where blobs auto-fire at waves of enemies and 5-6 bosses. WASD for P1, arrows for P2, gold shop between bosses. blobsiege.world

.io arena shooters

If the quick-room browser shooting is the draw, games like Krunker.io and Venge.io offer the same instant-match feel.

Co-op wave defense

Zombie Survival fans who want more structure can look at browser co-op defense games and voxel sandbox shooters.
