About this asset
The systems behind survivors-like / bullet-heaven games (Vampire Survivors, Brotato, Halls of Torment) as a drop-in framework. You bring the art; it runs the run.
What it does:
-Auto-firing weapons with seven behaviours: projectile, spread, area, aura, orbit, melee, chain
-Level-up draft with rarities, reroll, banish and skip
-Weapon evolutions: a max-level weapon plus a passive becomes a stronger weapon
-Spawn director with budget pacing, time scaling and scheduled elite and boss waves
-One stat system shared by characters, passives and permanent meta upgrades
-XP gems, magnet pickup, gold, health, revivals, run timer and win or lose
-Deterministic engine: same seed and input give the same run
Requirements:
-Unity 2021.3+. No third-party packages. The demos use Unity's classic Input.
Support:
Documentation is included in the package (README + Documentation).
From the publisher's Asset Store listing.
Technical details
Render-agnostic systems framework: the engine simulates the run and raises events, so it works in Built-in, URP and HDRP and in 2D or 3D with your own art and camera. Deterministic fixed-step engine with seeded RNG, spatial-grid enemy queries and pooled entities. Split into Runtime, UI, Editor and Demo assembly definitions under the FavenGames.Survivors namespace, single root folder, full C# source. No SDKs are bundled or required and it compiles clean on a fresh project. Meta progression saves through a swappable store (PlayerPrefs and file included). Designer tools: a setup window, a content validator and an engine-exact Run Balance Simulator.
