FINAL PRESSURE is a released top-down 3D zombie horde survival game built in Unity. The player fights through escalating pressure, collects cash-like XP pickups, chooses upgrades, secures optional specialist sites, and survives long enough to defeat the Commander.

The run starts with a permanent auto-firing Pistol and quickly grows into a layered survival loop. Defeated enemies drop resource pickups that fuel level-up choices. Workshop drops add weapons and support tools, while five optional specialist sites provide distinct tactical benefits around the Command Truck. The final sequence increases the pressure before the Commander enters the field; victory requires defeating the Commander while the player is still alive.
Weapons are intentionally low-friction. A collected Rifle equips automatically and returns to the Pistol when its ammunition is depleted. Shotgun, Rocket, and Flamethrower support fire trigger automatically when their target, ammunition, and cooldown conditions are satisfied.
- Desktop: move with
WASDor the arrow keys. Pause or resume withEscapeorP. - Mobile: use landscape fullscreen mode and the virtual joystick.
- Weapons fire automatically. HUD weapon slots show ammunition, availability, and cooldown rather than acting as selection buttons.
- Menus and upgrade cards use mouse or touch input.
Browser and device performance varies. The WebGL presentation uses an adaptive pixel-density strategy to preserve UI clarity without ignoring mobile GPU cost.

FINAL PRESSURE was built as a focused release project: complete a coherent game loop, make it readable on desktop and mobile browsers, and carry it through public distribution. The project went through substantial scope reduction and technical cleanup so the strongest playable loop could be finished instead of expanding into unfinished systems.
This repository is a curated portfolio showcase. It is intentionally separate from the private Unity production repository and contains no full project, licensed source assets, music files, WebGL build, private release URLs, or Git history.
- Auto-fire combat with Pistol, Rifle, Shotgun, Rocket, and Flamethrower behaviors.
- XP/resource collection and upgrade-card progression.
- Five optional specialist sites: Medic, Engineer, Heavy, Sniper, and Quartermaster.
- Workshop drops, Command Truck support, escalating enemy pressure, and a final Commander encounter.
- Desktop and touch input with movement ownership preserved across gameplay popups.
- Responsive HUD, fullscreen WebGL shell, and adaptive device-pixel-ratio handling.
- Object pooling and bounded update budgets for dense combat on mobile-class hardware.
- Explicit focus, pause, resume, restart, and audio teardown handling.
