🔪 FNF vs. Impostor V3 (Unblocked & Free)

FNF vs. Impostor V3 (also known as the Week 2 Update) is one of the most legendary crossovers in the rhythm game world. This total conversion mod brings the suspense of Among Us into the neon-lit battles of Friday Night Funkin'. You face off against a variety of colored beans—Red, Green, and the menacing Black Impostor—across multiple "weeks" set on the Skeld, MIRA HQ, and Polus. It’s famous for its high-quality music, dynamic backgrounds, and custom mechanics that perfectly capture the "sus" atmosphere of the source material.

This 2026 edition is fully optimized for HTML5/WebGL browsers, making it a top-tier unblocked choice for school or office networks. It runs smoothly on Chromebooks and includes all the classic tracks and cinematic cutscenes.

💡 The Crewmate’s Starter Guide

Don't get ejected! Master these basics to keep the beat going:

The Rhythmic Battle: Use the Arrow Keys or WASD to hit the notes as they reach the top of the screen. Your goal is to keep the health bar pushed toward the left (the opponent's side).
Week Structure: V3 includes four primary weeks:
- Vented (Week 1): Face off against Red on Polus.
- MIRA HQ (Week 2): Battle Green in the high-tech station.
- Skeld (Week 3): Take on the chaos in the iconic spaceship.
- Defeat: A secret, high-difficulty finale against Black.
Practice First: If "Hard" mode is too intense, start on "Easy" to memorize the song patterns. Each Impostor has a different "vocal" style inspired by Among Us sound effects.

🏆 Pro-Level "Sus" Strategies

📐 Ghost Note Management: In certain songs like Sabotage, the lighting might flicker or go dark. Don't panic—keep your internal rhythm steady; the notes are still there even if they become harder to see.
🛡️ Instant-Kill Mechanic: Beware of the Defeat track against Black. In this mode, missing a single note (or too many, depending on settings) can lead to an instant "Game Over." Accuracy is more important than speed here.
🔥 Secret Tracks: Check the Freeplay menu. V3 includes bonus songs like Double Trouble and Skinny Nuts that aren't part of the main story mode but offer unique challenges.
⚡ Note Offset: If the game feels "off," go into the Options menu and adjust the "Note Offset." On browser versions, a 10–20ms adjustment can often fix input lag caused by browser processes.

✨ Game Features

🎤 10+ Original Tracks: From the upbeat Sussus Moogus to the intense Meltdown and the haunting Finale.
🎬 Cinematic Cutscenes: Experience fully animated story moments where BF and GF actually interact with (and get chased by) the Impostors.
🖼️ Dynamic Stages: Watch the background change from a peaceful reactor to a total meltdown as the song intensity ramps up.
⚡ 2026 Browser Polish: Updated to run at 60FPS with reduced loading times, even on restricted networks.
