Extreme Run 3D is a high-speed endless runner built around reaction time. The course rushes toward you in three dimensions, obstacles arrive faster than they look like they should, and the run continues until you clip something.
It's a straightforward reflex test, and its virtue is pace: no menus, no story, no upgrades to grind. You press start, you run, you die, you press start again — usually about four times more than you meant to.
Use the left and right arrow keys to move between lanes and up or the space bar to jump. The run accelerates continuously and ends on your first collision.
No — it's an endless runner. The course keeps generating and speeding up; distance is the only score.
Yes. It's a light 3D browser game with nothing to install.
