Those are the Early Access launch counts. Every one of them goes up from here.

Meet the cast. You'll be killing all of them.

Fifty-four of them and counting, and every last one is convinced the field belongs to it. Here are six, so you know what's coming:

GRANDPA

Threat: extreme

Wheelchair. Shotgun. No brakes. Winds up from across the field, hits ramming speed, and detonates on arrival. Retirement did not mellow him.

THE COW

Threat: imminent

Strapped with eleven sticks of dynamite and completely calm about it. Doesn't run. Doesn't dodge. Just keeps walking at you until one of you stops existing.

TEDDY

Threat: sustained

Carrying a minigun that weighs more than he does. Somehow accurate. Would still like a hug afterward. There will not be an afterward.

MONKEY

Threat: escalating

Somebody left a crate of TNT unattended. That was a mistake. Now it rains lit explosives from wherever he's standing, which is never where you're aiming.

TIGER

Threat: unpredictable

Grenades, cooked way too long, thrown way too close. He knows exactly what he's doing. That's the upsetting part.

REX

Threat: airborne

Tiny arms. Full-size rocket launcher. Physically cannot aim down, so every rocket comes in at head height. Yours, specifically.

…and 48 more. The spitters spit, the chargers charge, the bombers sprint at you with the fuse already lit, the big ones split into small ones, and the small ones come in packs. Every 10 waves a boss shows up with a mechanic you will learn to hate personally. One of them eats your bullets and grows.

Nine ways to ruin a nice afternoon

Three modes are live today. The other six land during Early Access. Every run is seeded. Share the seed, replay the world.

Classic

The pure survival grind. One flat, open killing field: no walls, no cover, nowhere to hide. Endless waves, escalating forever.

Co-opEndless

Chaos

The same open field, cranked way past sensible. More enemies, meaner enemies, faster everything. The XP pours to match.

Co-opSpicy

Dungeon

Fight in a walled pit. A bounded, dungeon-dressed arena with no endless field to retreat into.

Co-opArena
SOON

Defend the Shrine

Hold the line. A fragile shrine at the centre must outlast the siege. Let it fall and the run is over.

Co-opObjective
SOON

Escort

Move the payload. Walk an objective to its destination while the horde tries to tear it apart.

Co-opObjective
SOON

Death Match

No mobs, no mercy. Just you and your so-called friends in an arena. Last one standing takes the bragging rights.

PvPRude
SOON

RPG

Equip armour and gear to build out your warden, RPG style.

In the oven
SOON

Magic

Drop the guns and fight with spells and raw wizardry.

Caveman

No guns, no magic. Rocks, clubs and raw instinct.

Top marquee: the 17 guns so far. Enemies drop them when they die. Grab three, swap on the fly, stack 36 perks on top: orbital blades, attack drones, lifesteal, guardian angels.
Red marquee: the 12 bosses. One arrives every 10 waves. Each has its own mechanic. None of them are your friend.

Okay, about the blood thing

The characters are round. The animals are lovely. The dismemberment is extremely real. This is the whole bit, live from the field:

Bring friends. Ruin friendships.

Up to 8 players, three ways to connect, zero platform drama.

Couch Co-op

Two players, one screen. Player 2 grabs a controller and drops straight in. The screen leashes you together, like it or not.

LAN Party

Host on your network, friends join by IP. No accounts, no services. Your router is the server, like the good old days.

Online Squads

Steam invites: create a squad, invite friends, ready up, go. Host-authoritative: one match, everyone in it.

8one match
Windows Mac Android iPhone Linux
  • Everyone plays with everyone. Yes, even iPhone and Linux. One host, five platforms, same run.
  • Full controller support on every platform: pads on PC and Mac, pads on your phone, remap everything.
  • Friend went down? Stand over them to revive. Or don't. They can watch the rest of the wave from the floor.
  • Level-up slow-mo is shared. When one of you gets a perk, everybody savours it.

House rules (the host decides)

Real match modifiers from the real lobby. Every run is seeded & randomized. Share a seed to replay a world. Drag the dials and watch the forecast.
