2D Infinite Character Forge - Alien Swarm

Unleash a procedurally generated alien swarm. 2D Infinite Character Forge - Alien Swarm Edition draws animated insectoid alien enemies in pixel art: swarmlings, warriors, acid spitters and armoured chargers, in endless variations from a single seed. Every creature is generated live in Unity from editable C# source, with no online service.

The creatures use the same slightly-front three-quarter view as the other 2D Infinite Character Forge editions, so they fit straight into a game built with any of them.

EIGHT SPECIES, TWO BODY PLANS

Four-legged:

• Skitterling – small, fast swarmling

• Stalker – eyeless warrior with a backswept crest and a bladed tail

• Spitter – carries a swollen acid sac on its back

• Ravager – large charger with a skull plate, horns and a club tail

Six-legged insectoids:

• Mite – small, many-eyed swarmling

• Reaper – warrior with raised scythe forelegs

• Bombardier – fires acid from a raised abdomen gland

• Bulwark – large armoured beetle with a horn

REAL SIZE DIFFERENCE

Small, Medium and Large size classes. Sprites are never scaled: a Ravager has more pixels than a Skitterling at the same pixels-per-unit, so the size difference shows in every scene and prefab.

FIVE HIVE COLOUR SCHEMES

Void, Bone, Dune, Blight and Ember. Every creature of a hive shares the scheme, so a swarm reads as one army. All seven colours of a scheme are editable.

ENDLESS VARIATION

Each seed varies spikes, horns, crests, tails, mandibles, legs, acid sacs, abdomens, armour bands and colour tone, while every species keeps its signature features. The same seed always gives the same creature.

WOUNDS

Cracked carapace, broken spikes and leaking acid-blood, in any combination. Wounds stay attached to the body in every frame of every animation.

EIGHT ANIMATIONS

Idle, Walk, Run (a fast sprint with dust), Hit, Attack, Bite, Spit and Die.

• Quadrupeds pounce. Insectoids rear and lunge. The Reaper strikes with its scythes.

• Spit fires on its own frame and reports the exact mouth position (the abdomen gland for the Bombardier).

• Die collapses the creature into a pool of acid-blood.

• Attack, Bite and Spit raise events at the moment they connect.

• Matching acid shot and splash sprites are included for every hive.

FULLY CUSTOMIZABLE

• Editor window with live animated preview, seed browser, size reference and every parameter editable

• Export PNGs, sprite sheets, acid shot sheets, presets, editable prefabs and baked animated prefabs

• Generate, edit and recolour creatures at runtime; save and load them as JSON

• Full C# source included

SWARM WAVE DEMO

A sprinting swarm charges a sandbag barricade in growing surges while the camera zooms out from a handful of creatures to several hundred, all generated live. Spitters lob acid over the wall, the defenders' fire cuts creatures down, and the survivors pile up against the barricade. After each loop, the next hive attacks. The battle runs on a separate C# simulation that you can use as a starting point for your own swarm logic. A gallery scene shows every species in every hive.

SUITABLE FOR

Sci-fi shooters, horde survival and bullet-heaven games, tower defense, base defense, RTS and roguelites, or any 2D project that needs a lot of alien enemies.

Includes optional URP lit material support, documentation and EditMode tests. Works alongside the other 2D Infinite Character Forge editions.
