Life Drain

Life Drain is a special mission.

Track
The track is shown on the right. Bloons will come in from the four entrances on the edges, and go around and around the middle square clockwise.

Life Drain blimp
In the center, in the middle of the space background, is the Life Drain blimp. The life drain blimp, when onscreen, Continually drains 0.02 life per second. (1 life per 10 sec). The point is, the LDB does not move, and drains life until popped.

Mission Basis
The mission is that whenever any type of bloon is onscreen, the LDB has a shield that cannot be broken or damaged in any way. To get rid of the shield, you must rid the screen of any bloons. Monkeys will always target other bloons over the LDB. The LDB has 120K HP. The player has 100 hearts, meaning you have 16 minutes and 40 seconds to beat the mission.

Rounds
The rounds are exactly like Apopalypse except there is a 3-second break between rounds to give time for your towers to attack the LDB.
