Research Facility

The Research Facility is a special mission

It has a special track with 4 entrances at the corners and 4 exits in the sides. These are connected by a ring in the center.

The bloons go counterclockwise around this for 225 degrees.

In the center of the map is a deactivated 4/4 hologram monkey.

Above the entrances are pedestals. Two have 0/0 tack shooters, the other two have 0/0 spike factories. Upgrade one of each to 4/x and the remaining two to x/4 to activate the hologram monkey, which works like a 4/2, with the following changes:

-The RoDs have 85 pierce instead of 75

-Range is 200 (4/1 has 190 and x/4 has 195)

-It has a modified version of the ability that takes 64 seconds to recharge instead of 72

-The base has a black antenna
