Operation Undead

**Round-based co-op zombie survival for Minecraft 1.20.1 (Forge).**
Team up with up to 3 friends (or go solo), hold off endless rounds of the undead, earn points, open up the map and see how far you can get. Every round the zombies get tougher, faster and more numerous.

> **Test release.** This is an early version for testing. Expect bugs and balance changes. Some features (like Serums) are visible but locked until a later update.

## How a run plays

1. **Gather in the Village.** It’s the lobby hub. Create a party, invite friends (Squad, up to 4 players) or play Solo.
2. **Pick your hero and mode.** The party leader picks the map and mode; each player picks a hero (each hero can only be taken once per party).
3. **Survive.** You start with a pistol and a few points. Kill zombies to earn points, then spend them to get stronger and push deeper into the map.
4. **Game over.** When the whole team is down, a camera tour of the map plays, you see a run summary, and everyone returns to the Village with their rewards.

Every run uses a fresh copy of the map, so nothing carries over between games.

## Features

### Spend points to survive
– **Wall buys:** guns drawn on the walls, from shotguns and SMGs to assault rifles. Later rounds sell higher-rarity versions.
– **Mystery Box:** gamble for a random weapon with a rolled rarity, including wonder weapons like the **Ray Gun** and **Thundergun**. The box moves around the map.
– **Doors and debris:** pay to open new areas. Doors can be split between teammates.
– **Power:** find the power switch to turn on perk machines, traps and more.
– **Perks:** drink perk-a-colas for health, faster reloads, quicker revives and other upgrades.
– **Armour:** buy a vest and armour plates to soak up damage.
– **Traps:** pay to activate traps that tear through the horde.
– **Barricades:** zombies tear boards off the windows; repair them for points.
– **Teleporter and Forge-a-Firearm:** link the teleporter to the mainframe, travel to the Forge, and upgrade your gun through three tiers of power.
– **Workbench and Arsenal:** trade scrap for plates and kits, and upgrade weapon rarity or add ammo mods (Cryo, Napalm, Dead Wire, Brain Rot, Fireworks).

### Enemies
– **Zombies** that scale every round, some wearing armour and helmets.
– **Hellhound rounds:** fast, burning dogs that come in packs.
– **Nova Crawlers:** crawling enemies that drop from ceiling vents and release toxic gas when killed.

### Equipment
Lethal and tactical equipment on their own keys: tomahawks, Monkey Bombs that lure the horde, decoys, flashes, smoke, shock charges and stims.

### Power-ups
Zombies drop power-ups that help the whole team, such as Double Points, One Shot kills, Max Ammo and Arsenal Sale.

### Down, not out
Get downed and your teammates have time to revive you. Self-revive kits give a last chance when you’re alone.

### Heroes
Four playable heroes, each with a role, a charged ability and a skill tree:
– **Nigen** (Tank)
– **Dr. Werner Klaus** (Medic)
– **Katouz** (Havoc)
– **Shaun** (Engineer)

Abilities charge over time and with kills. Each hero has three skill tiers with three choices each.

### Two game modes
– **Roguelite:** hero abilities, upgrade trees and between-round choices. Strike a **Devil’s Bargain** (powerful deals with a catch) or trade at the **Shopkeeper** and **Black Market**.
– **Classic:** the pure experience. Fixed prices, no abilities, no deals.

### Long-term progression
– **Levels and prestige:** level up to 55, prestige 10 times, then grind Master levels up to 1000.
– **Upgrade trees:** spend points earned from levelling on passive upgrades, hero skills and perk upgrades.
– **Missions:** daily, weekly and monthly missions with coin and booster rewards.
– **Achievements:** dozens of achievements to chase.
– **Shop and boosters:** spend coins in a rotating shop, including Double XP and Double Coins boosters.
– **Career:** full stats, run history, leaderboards and cosmetics.

### Built for zombies
– Custom HUD with points, round counter, team health, armour plates and a minimap.
– A Tab scoreboard showing every player’s live stats mid-run.
– The world is protected during play: no block breaking, placing or item dropping, so the map stays as designed.
