About the game
Action survival carpentry. Nail anything to anything: drag, nail and build with a physics based barricading system to hold off the horde. A combat focused zombie survival experience for 1-4 players in online co-op.
Original Steam description
Undead Development 2 is a combat focused zombie survival game for 1 to 4 players. Scavenge a point of interest for weapons and supplies. Fortify a location by dragging and nailing the furniture and junk into barricades. Fight your way from the forest to the city in Journey, or grow one base in Hideout Defense.
Nail anything to anything
The nailing system lets you nail anything to anything. Barricades are physics objects: drag a couch across a doorway, nail it down, and the horde has to break it to get through. Line the entrance with knives and bear traps, and research your way up to more advanced trap creation. There is no recipe list. Nail a bear trap to a door, a knife to a plank, a blade to a spinning machine, and see what holds.
Survive together
Online co-op for 1 to 4 players through Steam. One player covers the doorway while another nails it shut, then patches the barricade between waves while a teammate watches their back. VR and desktop players share the same lobby, and progression carries across solo and co-op.
Journey
Explore a gauntlet of biomes. Forest, swamp, city, each one harder than the last. Scavenge supplies from random points of interest, find a place to barricade and hold out. Survive until evacuation brings you to the next biome. Structured like a roguelite: random loot with rarity tiers, random events, random levels on the map. Hardcore death penalties are optional.
Hideout Defense
Evacuate a zone in Journey and it unlocks as a hideout. Pick one, fortify it, and defend it against wave after wave, improving the base between each one.
Progression
Research expands the loot pool: 40+ items at Early Access launch, and every one you unlock starts showing up in runs. Level up to unlock random player skins. Challenges pay out skins and trophy weapons.
Features
Desktop or VR, in the same lobby.

Strain: loop back through the biomes at a higher difficulty. Enemy health never scales, so nothing turns into a bullet sponge.

Dynamic systems: tree cutting, fire spreading, physics damage.
Minimalist interface. Interact directly with tools and items in the world.
FAQ
Do I need VR? No. Desktop is a full mode, and both play together.
Can I play solo? Yes, and progression carries over to co-op.
