Triggerhold

**Hold the line — one block, one trigger, one wave at a time.**

**Triggerhold** fuses first-person gunplay with tower-defense strategy and free-form voxel base building. You wake up at a procedurally generated stronghold on a single lane that runs from a zombie gate to an ally gate. Between each wave you get a build phase: gather Reserve, snap fortifications into place, wire up power and ammo lines, and let the automated defenses do the rest. Then the horde comes — and it comes harder every wave, in endless escalating waves until you break their three nests or they overrun yours.

### Build a fortress, defend it your way
Drop walls, sandbags, steel bulwarks and iron traps, then bristle the ramparts with sentry turrets, auto-sentries, flame traps and Tesla coils. Blocks have real health, adjacency bonuses and functional links — production blocks feed nearby devices with ammo and power, unsupported blocks fall, and everything the zombies touch can be repaired or rebuilt. Each match rolls a fresh battlefield, so no two defenses look alike.

### 12 classes, 12 ways to die differently
Switch roles and the whole meta changes:
- **Engineer 工程师** — repair gun, turrets, a robotic arm that auto-builds, plus deployable machine-gun robots and recon drones.
- **Machine Gunner 机枪手** — a minigun with 3× fire rate, sandbag cover and a fast ammo station.
- **Assault 突击手** — high-rate SMG with extended hit stagger, spring launchers and quick deployable cover.
- **Demolition 爆破手** — grenade launcher, timed charges, TNT printers and a 30-grenade volley rig.
- **Flamethrower 喷火兵** — sustained burn, fuel boosters and ember fountains.
- **Medic 医生** — slow-stacking heal gun and a syringe that *converts zombies into allied teammates*.
- **Future Soldier 未来战士** — energy shield, chain-lightning gun, Tesla generators and a fusion reactor that nukes itself when destroyed.
- **Heavy Trooper 重装兵** — double health, heavy armor, a steel bulwark and belt-fed support rigs.
- **Sapper 布雷手** — step-triggered mine launcher, an auto mine-layer, a self-detonating explosive cart and reactive-armor barricades that blast back.
- **Lumberjack 伐木工** — saw-blade launcher, a fuel-hungry chainsaw, fast-yield ammo crates and a powered saw platform.
- **Bouncer 球手** — a ricochet ball that bounces up to 10 times, buffed by elastic, spin and precision launch pads.
- **Disinfector 消毒工** — a chemical sprayer whose toxic mist chews through the horde, plus breakable gas canisters and guides that drag the cloud onto zombies.

### A living three-way battlefield
Beyond the zombie tide, a MOBA-flavored single lane runs in parallel: your three forward bases (each with a bound guard) face three zombie nests along the same corridor. Friendly helicopter drops push toward the zombie gate, terrorist squads raid from the flanks, and neutral NPCs can be recruited to your side. Tamed allies, deployed voxel robots and drones all fight on their own agendas — your job is to keep them all fed with ammo and power. Destroy all three nest hearts to win; lose all three base guards and the line falls.

### Endless waves, escalating forever
Thirteen zombie archetypes — fast, tank, exploder, spitter, pistol, eggspawner, charger, bone, plus ranged sprayers, soulbearers that raise buried zombies and shockwave screamers — cycle through an endless run, each **Boss wave landing every 5 waves**. There is no "level 20" to reach: the front keeps ramping until you break their nests or they break yours. A **Faction Terminal** lets you spend resources to escalate the troops, strength and unit types of a single wave, turning a defensive last stand into a coordinated counter-push.

### Key features
- **First-person shooting + tower-defense + voxel building** in one loop.
- **12 distinct classes**, each with a signature weapon, exclusive functional blocks and gadgets.
- **Deep build economy**: health, adjacency, power/ammo supply lines, repair-and-rebuild.
- **Three-faction living battlefield** on a single lane with 3 depth objectives per side; recruitable and tameable NPCs.
- **Endless escalating waves**, 13 enemy types, a Boss every 5 waves, and a Faction Terminal to power your counter-push.
- **Voxel combat robots**: deploy MG robots and recon drones, and convert powered-down enemy lane robots into persistent teammates at a Robot Terminal.
- **Procedurally animated soldiers & zombies**, blood, fire, toxic gas, explosions and shield effects.
- **Bright cartoon voxel look** — every block carries accent-tinted relief detail, rigged zombies wear hand-set outfits, and blood, fire and toxic gas play out in full daylight.
