The Best Free Online Action Games
I strongly believe an online action game, should actually require your ACTION. Clicking a single mouse button at the same spot over and over again doesn't really count. That's why our action section is really diverse, with games ranging from IO Games, through Racing Games, all the way to Shooting Games.
Popular Action Games
A game that is filled with action, but also has a car accent is Crazy Car Stunts. Choose a vehicle of your choice (no really - tanks, cars, trucks, a bus...) and do as much stunts as you please! If you're up to a more racy-kind of thing, Furious Drift is the closest thing to the real deal in terms of a no-download online game.
Simpler, but as much fun online action games are Chaki Sky Jump and Arctic Pong.
Among the classics, there are two gorgeous games. The first one is actually the first FPS in the world. originally created for SEGA and other consoles, now it's available as an online game - Shoot the Duck. The other one is a modern-day classic online game. Coming from Zuma's Revenge and Zuma Deluxe, Zuma Online is a way to enjoy the series in-browser, with no downloads.
And if you're up for a decent action first person shooter online, then Paintball Shooter or Krunker.io would be your best choice.
Miami Crime Simulator is a 3D shooting action game, that will take you in a world, where you have to get rid of all your enemies. You can choose between using a standard weapon, or to jump in a tank or a chopper and get the job done properly!
Dumb Ways To Die: The Original, Dumb Ways To Die 2: The Games and Dumb Ways To Die 3: World Tour are also worth trying. This game became an instant classic right after it came out. Try and see if you can handle all the tasks (note: A lot of action is required in this browser game sequence!).
Elevator Breaking will mostly require mouse action, but that doesn't mean it's easy and you won't have to be focused all the time! On the contrary... one small error can fail you.
