FNF: Vs Sonic.EXE 2.5 / 3.0
FNF: Vs Sonic.EXE 2.5 / 3.0 is a Friday Night Funkin' horror mod, the unfinished update with eighteen songs.
When the project was canceled, one of its coders released the build as it stood. Even unfinished it is enormous: three weeks and a whole line of corrupted Sonics waiting for Boyfriend.
How to Play FNF: Vs Sonic.EXE 2.5 / 3.0?
Arrows scroll up in four lanes and you press the matching key as each reaches the top row. Hit them to push the health bar your way. Miss too many and it tips to your opponent and the song ends.
All three weeks are open from the start. The first is the Encore set: remixed takes on Too Slow, You Can't Run and Triple Trouble. The second brings Prey, Fight or Flight, Round a Bout, Fatality, Milk, Too-Fest and Personel. The third holds Endless, Endless OG, Cycles, Sunshine, Soulless, Faker, Black Sun and Chaos. The opponents run from Majin to Fleetway.
Note: this is the unfinished build exactly as it was released, so some rough edges are the mod's own. It is a big download, so the first load takes a while on slower connections, and a few text labels use a stand-in font in the browser.
Tips and Tricks:
- Be patient on first load: It is a big mod and takes a moment to download.
- Start with Encore: The first week remixes songs you may already know.
- Use Free Play: Every song can be picked on its own.
