Grappling, weapons and cover
Aim at a surface and press E or right click to hook it. Hold W while attached to reel in faster. Release the hook to carry your momentum through the arena.
Each loadout has five weapon slots. Try a close-range weapon, a long-range weapon and an explosive to learn how they handle. Charged weapons fire when you release Fire after charging. Remote explosives detonate when you fire again after a charge sticks. Empty weapons reload automatically when you try to fire.
Towers and platforms can break apart during a fight. Watch the cover above and around you: collapsing structures can damage fighters underneath.
Choose a game mode
- Quick Play: fight up to 15 bots locally. Pausing freezes the local match.

- Private Room: create or join an online room with a shared room code. The host starts the match when the group is ready.

Frequently asked questions
Is Master Blaster free, and do I need a download?
Master Blaster is free to play in your browser. You do not need to install an app. The browser loads and prepares the game resources when you visit.
Can I play Master Blaster offline?
Quick Play and Training run locally against bots. First visit while connected and let the home menu finish preparing resources. When it reports Available offline, this browser has saved the game for offline visits. Private Room and Global Multiplayer require an internet connection. Browsers can clear saved data, so offline availability depends on retaining those resources.
How do I play with friends?
Choose Private Room to create or join a room using a shared room code. Wait for your friends in the private lobby; the host starts the match. Global Multiplayer lets you find open games or create a public game that appears in the global lobby.
Can I play on a phone or tablet?
The game has touch controls for movement, aiming, firing, jumping, grappling and weapon switching. Use landscape orientation for more space. Performance depends on your browser and device; try Low graphics in Settings if the game runs slowly.
What should I do if the game runs slowly?
Open Settings and choose Low graphics. You can also reduce bot count before a match. Reduce motion and flashes is available in Settings. Keep hardware acceleration enabled in your browser; more demanding graphics effects depend on your device's capabilities.
