Battle SWAT vs Mercenary Remaster is a free online multiplayer FPS game where you choose a side — disciplined SWAT soldier or ruthless mercenary — and fight for control across fast-paced combat arenas. Built in WebGL and Unity, it runs straight in your browser with zero downloads required, making it one of the most accessible unblocked shooting games available right now.

The game packs real variety into its modes. Standard team battles keep the action tight and competitive, but the zombie mode is where things get genuinely unpredictable — players who die can respawn as zombies and hunt down survivors, flipping the entire match dynamic mid-game. Controls are straightforward: WASD to move, mouse to aim and shoot, with Tab pulling up the menu. Switching guns mid-fight and managing positioning are the keys to surviving longer rounds. Each faction feels distinct enough that swapping sides actually changes how you approach combat.

This game is a solid pick for fans of unblocked multiplayer shooting games, browser-based FPS action, and anyone who wants a quick zombie shooter without installing anything. If you enjoy games like Krunker or Shell Shockers but want a team-vs-team structure with a zombie twist, Battle SWAT vs Mercenary Remaster delivers exactly that. Search terms like 'free SWAT vs mercenary game', 'unblocked FPS multiplayer', and 'browser zombie shooting game' all lead here for good reason.
