Skeleton
Undead · from wave 1
All bones, no brakes. It sprints, and from about ten meters out it pounces at where you were. One bullet takes it apart — if your bullet gets there first.
Bestiary
They rise out of the ground a row of voxels at a time and take no bullets until they're all the way up. Each biome adds its own and keeps the ones before. HP at wave 1.
Undead · from wave 1
All bones, no brakes. It sprints, and from about ten meters out it pounces at where you were. One bullet takes it apart — if your bullet gets there first.
Undead · from wave 1
Hunched, bone-white skull, a little armor where it counts. It comes in quicker than a zombie and leaves sooner, which is the only nice thing about it.
Undead · from wave 2
The purple one. It limps, it hits hardest of the three, and it has never once asked itself whether this is a good idea.
Undead · from wave 5
Drifts in half-seen. Your first shot goes straight through it. Then it blinks to your side, holds still for a heartbeat, and dives. Step out of the line.
Beast · from wave 8
A wall with a pumpkin for a head. Thick armor shrugs off small rounds, and its arm slam lands where you're walking to, not where you are.
Undead · from wave 12
Flies in on a broom and drops acid potions on you. The puddles stay longer than she does.
Boss · wave 20 · The dead obey
His kingdom fell centuries ago. He never learned how to surrender.
He greets you with one word: "Kneel". Then come the green orbs, six pulses at a time, and skeletons thrown across the arena like cutlery. At half health he raises twenty to forty of them at once.
When he falls, he isn't quite finished. A giant skeletal hand grows out of the ground where he stood, turns to you, and comes down palm first. Stand between the fingers, or be somewhere else.
Beast · from wave 3
A bag of acid on legs. It runs in, it pops, it leaves a puddle that hurts you and everyone else standing in it. Shoot it somewhere far away.
Beast · from wave 4
Hangs back, takes aim for most of a second, and spits a slow red orb. The orb is easy to dodge. The fourth orb, from the fourth bat, less so.
Beast · from wave 5
Horns first, questions never. It charges without a warning and moves you across the arena whether you had plans or not.
Beast · from wave 6
Kill it and it turns into several smaller, faster problems. Splitlings fall to a single bullet, which is good, because there are a lot of them.
Undead · from wave 7
Keeps its distance and casts boons on the others. When it dies it bursts into orbs — one last spiteful gift for whoever did it.
Boss · wave 20 · The nest wakes
She brought the whole family. And you're on the menu.
She dashes sideways, stops, and hatches a brood of spiderlings — ten, then fourteen, then more. Her web pins you in place for three seconds; you can still shoot, you just can't leave.
At half health she gets angry: twice the dash, twice the brood, and every fourth hatchling is full of acid.
Goblin · from wave 3
A goblin, a bag of lit bombs, and no sense of personal space. Each bomb takes a moment to go off. Spend the moment walking.
Goblin · from wave 4
Drops in under a patched canopy, plants its feet and fires bursts of four. It isn't going anywhere. Neither should you be, in its line.
Undead · from wave 5
A red wedge on the ground is its way of saying "you, specifically". It stops, aims, and fires a beam down the wedge. Leave the wedge.
Boss · wave 20 · Death from above
They sent him to break the siege. There was no city left to save.
An armored goblin artillery commander. Rockets fall on marked ground, bombs bounce in after you, and clusters of mines close off the places you were going to dodge to.
He has to reload eventually. That's your window.
Demon · from wave 1
Runs at you until you're at whip's length, stops, and draws a red line on the ground. The lash follows the line. Stop, or back off.
Boss · wave 20 · Every crown comes off
Keep your distance. Cross the chain. Escape the axe.
The Last Headsman. His chain flies straight and fast and pulls you in; his axe sweeps a wide arc in front of him; the ground around him burns. Running along the chain is a mistake you make once.
When he is enraged, the safe ground shrinks to one part of the arena, and the pull comes with the axe straight after.
Goblin · any wave, by luck
A loot goblin with a sack of gold that isn't his. He doesn't fight; he runs, fast. Catch him and the sack is yours: the only gold you'll find in the arena.
