About the game
One keep still stands.
The kingdom has fallen. One keep still stands, and you and up to four friends are all that is left of its defenders. Hold the walls through every wave, rebuild between them, and turn a ruin into a fortress worth dying for.
Glory won in battle belongs to the whole kingdom. Spend it to raise the town, rebuild the Blacksmith and the Mage’s Tower and arm the towers. Then shout PAPI, BLIZZARD or HOLY NOVA into your microphone and watch the sky answer.
“Five voices. One Holy Nova.”
The last defenders of the keep
Voice casting · optional
Shout your spells
Say it into your microphone or press a key. The keep doesn’t mind which.
-
PAPI
Three fireballs from your staff. A full party shouting it at once: fifteen.
-
BLIZZARD
A storm of ice that freezes a whole file of attackers at the gate.
-
HOLY NOVA
The co-op ritual. Every living defender casts within 2.5 seconds, and the keep answers.

Features
What's inside
-
Build the keep
Every town level visibly transforms the city, from a broken keep with boarded windows to a fortress of banners and stained glass.
-
Forge your hero
Staff or sword, shield or speed. Time a parry right and arrows, even the Red Bishop’s blood orbs, fly straight back.
-
Shout your spells
Cast PAPI, BLIZZARD and HOLY NOVA with keys, a gamepad or your voice. Five friends yelling PAPI means fifteen fireballs.
-
Defend it together
Online co-op for 1–5 players with invite codes and no port forwarding. Fit the towers with twelve weapons and let the council vote on what to build.
-
Trace the runes
Trace the rune on a TNT balloon and drop its cargo on the horde instead of your walls.
-
Survive the Blood Storm
When the Red Bishop arrives the sky bleeds. Every living defender must join HOLY NOVA within two and a half seconds.
