Rescue trapped Monkey Engineers! Each one you free before the bloons reach them is yours to use during the rest of the mission. Free at least one to pass the mission and unlock the Monkey Engineer.
~ Bloons Monkey City Mobile level description
Initial Engineer

The initial setup of the mission

There are 5 Engineers that are trapped in cages along the path. Your job is to free at least 1 of them (or defend them all) and beat all 15 rounds. It costs $450 to free each one and each one can be placed as a free tower. Engineers disappear if bloons touch them, and pop themselves, if you haven't freed them. If you do not free at least 1 Engineer and all Engineers are gone, it's instant Game Over. The highest bloon rank is ceramic. Note that there will be regrow and camo bloons in the mission; fortunately there won't be camo or regrow ceramics.

There is some water in the darkish waterholes of the swamp, where Monkey Buccaneers and Monkey Subs can fit in (though almost no player would unlock the Monkey Sub before they would unlock the Engineer).


Qwertyxp2000 the second's strategyEdit

Engineer solution strategy Qwertyxp2000 the second

Qwertyxp2000 the second's solution on the last round

I had $1850 starting cash. First, save the first two Engineers. Place each one near where it had got out of its cage. Then upgrade the first one to 2/0. Try to upgrade some to 3/0-2. Put the next 3/0-2 adjacent to the other side of the path, and attempt to make its radius occupy as much path as possible. I countered pesky camos and leads with a 2/2 Monkey Apprentice, near and slightly in front of the engineers. Save more Engineers after upgrading the others to 3/x. The next one I put was a 2/3. Even though I unnecessarily saved the last two, I still managed to complete the mission without losing any lives!

Because I had beat this mission before Version 1.7; no Monkey Knowledge is required in this strategy, although it is advisable to rank up the Monkey Engineer to Rank 3.



  • If you sell an Engineer, you do not have to pay $450 to put him back on the track.
  • You can upgrade the Engineer to any upgrade in this level.
  • You don't have to free all of the 5 engineers to win. Therefore, trying to free all 5 does not give an instant win.
