Tarkov-style loot-and-extract backend for Unity: spatial-grid rig, weighted loot, conditional extraction, traders, tasks, hideout, insurance, crafting, saves, and an engine-exact economy simulator.Build an extraction-looter, not the plumbing. This is the deterministic, art-free backend behind the genre. Bring your own art and combat.Spatial-grid rig: place and rotate loot into a limited grid. Squeeze in the rare, drop the cheap, and run.Risk-and-extract loop: loot weighted containers, watch survival fall as you get greedy, then extract to keep it or die and lose the rig.Conditional extractions: timed, fee-gated, item-gated or contested exits.Meta economy: traders with reputation pricing, a task chain, a hideout with upgrades and passive income, secure container, insurance and a persistent stash.Crafting: consume stash items, deliver the output after a set number of raids.Raid Economy Simulator: forecast hundreds of raids on the real engine. Reads survival %, net-per-raid and the profit curve, and warns on punishing, unwinnable or too-generous economies.One-click validation, deterministic seeded RNG, exact JSON saves.Drop-in uGUI plus an unbreakable IMGUI HUD. Single-player first, async-PvP ready (off by default, no SDK).Add the ExtractionDemoArena component to an empty scene and press Play for the full loop, then use Tools > Faven Games > Extraction > Create Sample Content to author it as real assets.Pure C#, event-driven, UI-free core engine.Deterministic seeded RNG (xorshift128+); exact JSON save/load including the RNG stream.ScriptableObject content: items, loot tables, traders, tasks, hideout modules, recipes, maps and one config.Assemblies: FavenGames.Extraction (Runtime), .UI, .Editor, .Demo. No third-party dependencies.No generative AI art, audio, or 3D models are included in this package. Allmarketing images are rendered programmatically with Python (Pillow), not anAI image generator.
