LAST BASTION.

A BIGGER PLACE TO MAKE YOUR STAND

The 100 × 100 arena has about 70% more floor space than the campaign arenas. Four open outposts surround a central reactor, with wide outer routes and cross-lanes. Use walls to break projectile sightlines, then move before the crowd surrounds you.

THE SIEGE KEEPS GROWING

Wave one starts with 19 monsters. Each wave adds three, up to 80 monsters per wave, with at most 32 alive at once. Regular enemy health gains 7.5 percentage points per wave and damage gains 3.5; movement, attacks and projectiles also accelerate up to their caps. Every fifth wave ends with a Siege Tyrant. Waves keep generating for as long as you survive.

RECOVER. RELOAD. GO AGAIN.

You start with 100 health, 50 armor and the same three weapons as the campaign. There are seven seconds between waves. Each new wave after the first restores 20 health and adds 110 rounds and seven rockets. Health, armor and ammo pickups respawn around the map.

ONE MORE WAVE IS THE RECORD

The dedicated leaderboard sorts by waves cleared, then total kills, then longer survival time. A wave counts only once every monster is down. Clear at least one wave, then submit a callsign after defeat, or press Escape and choose End & Submit Survival Run. Closing the game or choosing Main Menu discards the unfinished ranked run; runs cannot be resumed. Your best wave and kill count are also saved locally.

These are casual community rankings with server-side timing and progression checks. They are not cheat-proof.
