Budget: $30 – $250 AUD
MUTANT FORGE — FULL GAME DESIGN DOCUMENT (Developer Version)
1. Game Overview
Mutant Forge is a creature‑building, exploration, and combat game where players collect DNA, craft custom creatures, and battle in physics‑based arenas. The core fantasy is becoming a rogue scientist in a broken world, forging powerful mutants from scavenged parts and mutations.
The game blends:
Creative building
RPG progression
Physics‑based combat
Exploration
Randomized mutations
Live events controlled by admins
The experience is designed to be replayable, social, and highly customizable.
2. Core Gameplay Loop
Players repeat this loop:
Explore different biomes to collect DNA, materials, and rare creature parts.
Forge a creature using a drag‑and‑snap building system.
Mutate the creature with random perks and stat bonuses.
Battle in PvP arenas, PvE gauntlets, or boss hunts.
Earn XP, DNA, and rare parts to upgrade their creature.
Return to exploration to find better materials and repeat.
This loop ensures long‑term engagement and progression.
3. Creature Building System
The creature builder is the heart of the game.

Mutations are random bonuses that make each creature unique:
Double‑jointed legs (speed boost)
