Mutant Assassin 3D
By Bestgames.com
Mutant Assassin 3D puts you in the boots of a web-launching special agent clearing out mutant goons stage by stage. You aim your shots, tangle each enemy in webbing, then move in and punch them out, working through four levels before a final boss. Money picked up along the way stacks in the counter at the top. It runs free in your browser on desktop and mobile, no download.

How to Play Mutant Assassin 3D
Each stage drops you on a narrow tiled walkway with red boundary lines marking the path. You hold and drag to aim the web launcher, firing at the mutant enemies ahead of you. A small icon panel above the action shows your current target status — a green check for a foe you have dealt with and a plain silhouette for one still standing.
Once an enemy is wrapped in webbing they stop fighting back, and that is your cue to close the distance and hit them with punches. The view shifts between a third-person look at your agent and a first-person shot of your gloved hands as you swing. Cash bundles drop around defeated enemies and on the floor of the corridor, and the counter in the top-left tracks the total, with a Last: readout for what you just picked up.
Clear every foe to finish the level. Four levels lead into a boss encounter, and the game gives you no route hints — you work out the best approach yourself.
Tips
- Web an enemy first — once they are wrapped up, closing in for punches is far safer than rushing them.
- Sweep the corridor floor for dropped cash bundles before you move to the next group; they sit in the open on the tiles.
- Watch the target panel above the screen: a plain silhouette means someone is still active and worth finding before you push forward.
- Save your focus for the boss stage after level four — it comes with no guidance on the best route.
