Clear every wave. Every 3rd wave is a boss — there are 50 of them, each meaner than the last.

Steer with WASD, aim with the mouse, fire with click or Space. On phones use the D-pad and FIRE.

Hold Shift (or BOOST) to sprint at 1.65x speed. It drains the orange stamina bar, which refills when you ease off.

Every class has a signature power on E: invincibility, EMP, fire ring, ghost step, shockwave, or overclock. It recharges over time.

Green orbs heal you AND permanently grow your max health and stamina. Bigger kills scatter more orbs — farm the big snakes.

Every gun stays in your belt and duplicate pickups stack reserve ammo. Press 1/2/3 for the first three slots; Q/C, wheel, SWAP, or a belt click accesses the rest.

Press F or use ASSIST to cycle Manual, Auto Aim, and Auto Fire. Movement stays manual, so you can focus on forming a defensive coil while the assist tracks threats.

Blue runners are fast, purple brutes are tanks, yellow snipers snipe from across the arena, orange rushers charge straight at your head, and THE REAPER — a long pink snake — boosts in and coils around you. Do not let it close the circle.

Your tail is a weapon. Any enemy that runs head-first into your body dies on the spot — encircle them, cut them off, farm the orbs they drop. Your own tail never hurts you.

Enemies dodge your bullets and circle you. Head-on crashes hurt both of you badly. Lead your shots, keep moving, and never fight in a corner.
