Evolution Arena Battle Royale

Evolution Arena Battle Royale starts you as a worm and asks you to fight up the food chain, unlocking a bigger animal each time you earn Evo Points.

Every kill feeds the same currency. Beating wild creatures and rival players earns Evo Points, points unlock the next animal form, and each form survives fights the previous one could not. The arena opens into new biomes as you climb, so the pressure is to keep moving up rather than farm the same corner.

On a keyboard you move with WASD or the arrow keys, attack with the left mouse button, jump with space, and hold the right mouse button to swing the camera around. On a phone the same actions sit on a virtual joystick with separate fist and jump buttons, so nothing is lost on touch.

It is a full 3D build and takes a while to appear the first time. Once it is up it runs in the browser with no download and no account.
