FNF V-Slice is the foundation of the modern official game. This series is organized for new players who want one clear path through the topic: what V-Slice is, why the engine changed, how the gameplay feels, and how official modding works on PC and mobile.
Quick start
| Question | Answer |
|---|---|
| Where do I play? | Newgrounds (web), Itch.io (PC), Google Play / App Store (mobile) |
| Am I on V-Slice? | Official builds from April 2024 onward (v0.3.0+) use the FNF V-Slice codebase. Check the version on the title screen and compare it with GitHub Releases. |
| Is V-Slice a mod? | No. It is the official engine rewrite, not a separate mod or beta branch. |
| Do Psych Engine mods work here? | No. Official mods use Polymod + HScript. Psych and Kade mods target different engines. |
