2D Infinite Character Forge - Apocalypse

2D Infinite Character Forge – Apocalypse Edition is a procedural pixel-art character generator for end-of-the-world games. It has no pre-made sprite sheets. Every person is drawn by C# code, in the Editor or live at runtime, so you can create unlimited unique survivors, zombies, fungal hosts and mutants from a seed.

Who’s in it
There are 22 roles in four groups. Authorities: police, riot police, firefighter, paramedic, soldier and hazmat trooper. Civilians: office worker, construction worker, doctor, nurse, chef, mechanic, farmer, student and business person. Survivors: prepper, looter, hunter, prison guard, prisoner and security guard. Scientists: a lab researcher. Each role has its own clothes, headwear, gear and colours. People vary by age, build, skin tone, hair, beards, glasses, scars and tattoos.

Infection, step by step
Any person can be healthy or infected. Zombification has five stages, from a fresh bite to a decayed corpse with bare bone. Fungal infection has four stages, from threads under the skin to a head buried in growth. Mutation has four levels. The layers combine, so a rotting zombie can also be overgrown with fungus and mutated. Clothes and gear decay along with the body, but the uniform stays recognisable: a dead police officer still looks like a police officer. Mutants can grow into giants about 1.5× as tall. Giants are real larger sprites, not scaled ones, and can carry a minigun, flamethrower or plasma gun.

Gear that tells the story of the outbreak
Every item has a material, a craft level and a condition, shown as dirt, rust, patches, tears, dents and blood. Outbreak phases age a whole outfit at once. On Day One gear is clean and as issued. After weeks it’s worn, after months it’s reinforced, and after years it’s mostly scavenged and taped together, with improvised side armour such as sports pads and taped magazines.

Animated and game-ready
There are 20 animation slots: standard actions (idle, walk, run, jump, attack, shoot, reload, die and more), zombie-specific slots (Shamble, Lurch, Grab, Bite), Throw (grenade or Molotov) and Kneel Shoot. Animation events (shoot, attack, reload, throw, completed) let your gameplay react at the right frame. You can export PNGs, editable prefabs, baked animated prefabs with sprite atlases, or JSON presets.

Fully customizable
Everything is editable in the Editor window or through the runtime API. You can change role, phase, quality per slot, infection stage, and single details such as eye type per side, wounds, exposed bone, growths and colours. Characters are stored as serializable data, so you can generate, save, load and change them at runtime: for example, turn a survivor into a zombie when they’re bitten. You get the full C# source, and the engine is plain C# with no UnityEngine dependency.

Suitable genres
It’s built for zombie, fungal-infection, mutant and post-apocalyptic games: survival, tower and horde defense, top-down and side-view shooters, roguelikes, strategy, colony and management sims, RPGs and tactics games. It works well wherever you need large crowds of distinct characters. The included Standoff demo generates almost two hundred characters live on a city street. The modern roles and catalog also suit present-day settings without the apocalypse, such as city, police, emergency-services or crime games.

Included
87 C# scripts, an Editor window and exporters, two demo scenes (Showcase and Standoff), optional URP lit-sprite shader, 48 EditMode tests and full English documentation. No dependencies required. Works on all Unity platforms. Unity 2022.3 or newer.

Scope: The package is visual only. Animations, infection and gear wear are graphics; movement, damage, infection spread and AI are handled by your game.
