|End of Infinity|
End of Infinity is a track that is similar to the infinity symbol, taking place at a surreal place. It's unlocked at Rank 32.
The bloons comes from the top, go around the infinity symbol then leave to the bottom. There's a "not really visible" part under the "straight ways" for bloons to hide.
This track itself is pretty simple, but the majority of its difficulty comes from how limited the tower-spawning area is, as the majority of the track is Outer Space.
The boss for this track is the E.N.D. O.F. I.N.F.I.N.I.T.Y. but it only appears on hard.
