X Factor is an Advancedmap in Bloons TD 6, introduced in version 22.0. It takes place in a wooded area with four paths that intersect in the middle. This map was created to promote the Dartling Gunner, which was released in the same update.
This map has 4 entrances and exits for almost all purposes, but there are 8 total sets of pre-game prep spikes on this map, likely due to the splitting of the Bloons into 2 separate paths through the mini-circles. The Bloons enter from the top-left and the top-right on round 1, and the locations of the Bloon spawns rotate by 90° clockwise every round, thus the Bloons spawn and exit at the same spots every 4 rounds. The barrack in the middle blocks all Bloons, including blimps, from being attacked, significantly increasing this map's difficulty. The stack on top of the barrack can be removed for $2000 and can fit all towers except the Banana Farm.

Recommended towers and upgrades
For heroes, Psi is a good choice, since they can attack from anywhere on the map and catch Bloons before they leak. If placed near the center, they can also use abilities to stun both sides of the track.
Sniper Monkeys are a cheap yet powerful option, since they can target all exits and the map has no line-of-sight blockers.
