Submarine Alliance

"Join forces with the Monkey Subs and defeat the ZOMG bloon. Doing so will unlock the Monkey Sub for use in your city!"

- Bloons Monkey City Mobile level description

There are 4 1/1 Subs defending a broken 2/4 Sub. Your job is to repair it for $8000. There isn't much land or track in either direction and there are 15 rounds, so good luck. There's a ZOMG at the end, hence the urgency to repair the 2/4 sub, but there are also MOABs in the way. Bloons travel towards the broken Sub at the middle with 2 paths. Also, the ZOMG is not the only bloon in round 15. Many said this is the hardest tower mission in BMCM. When reaching round 15, you should get correct timing to destroy the ZOMG otherwise you will lose.

Trivia

 * The ZOMG is the first bloon in Round 15 only coming from one side, but at the end of Round 15, two MOABs come out.
 * The 4 1/1 Subs cannot be upgraded.
 * There are Regan and Camo bloons in this level. Regan bloons start in Round 5 as Blue Regan bloons and Camo bloons start in Round 5 as Red Camo bloons.
