Monkey City MOAB Strategy Guide
This site is for Bloons tower defense strategy guide, tips, and tricks.
Unlike easier difficulties, Hard Mode introduces higher costs for towers and upgrades, making money management crucial. Standard strategies from Medium mode will quickly lead to financial ruin.
The main challenge in the early rounds is squeezing out enough cash to fund your initial towers without leaking lives to bloons. It's often necessary to treat lives as a secondary resource, tolerating the occasional leak if it means securing that vital early Monkey Farm before Round 12.
The primary error players make is over-defending. Placing a single unnecessary tower during the first ten rounds delays your cash gain by a full round, creating a negative compounding effect that ruins your cash flow by the time the mid-game rushes arrive. You need just enough defensive presence to survive, funneling every other drop of income directly into generating more revenue.
The precise timing for shifting your economic focus is a key detail often overlooked in general strategy guides.
While building 2-0 Banana Farms is a well-known cost-effective starting point, knowing when to transition from these basic farms to a more lucrative 4-2 Banana Factory is important. Our analysis indicates that Round 26 serves as a critical juncture for this transition.
Continuing to build 2-0 farms past Round 26 will leave you short on funds needed to counter the camouflage, lead, and ceramic rushes that become prevalent in the round thirties. At this juncture, halt all farm expansion. Utilize the steady income from your existing farms to build a robust defense, perhaps a 3-2 Ninja Monkey supported by a 2-2 Monkey Village. Once this core defense is secure, you can then focus on accumulating the capital needed to upgrade your farms to 4-2 Factories, maximizing your income without jeopardizing your survival.
When deciding on an opening strategy for tough maps, generic advice often points toward spamming cheap Dart Monkeys. However, this strategy fails completely on maps with short, complex track layouts where a limited footprint leaves no room for error. On these compact paths, the performance difference between a Monkey Engineer and a Ninja Monkey becomes incredibly apparent.
A 2-1 Ninja Monkey is highly reliable because its seeking shurikens track targets perfectly, maximizing its pierce capacity even when blind spots or sharp corners disrupt its line of sight.
On the other hand, the Monkey Engineer offers a completely different tactical advantage by dropping autonomous sentries. On ultra-short tracks, these sentries act as a decentralized defensive network, spreading out firepower and blocking leaks across multiple areas at once. The catch is that the Engineer relies heavily on random sentry placement, which can occasionally leave gaps. On tight maps, the choice comes down to track layout: use the Ninja for predictable, targeted damage on winding corners, and deploy the Engineer on short, intersecting paths to maximize total early-game map coverage.
As the rounds progress into the late twenties, individual targeting towers lose their effectiveness against massive waves of grouped Black, White, and Lead bloons. This is where the Bomb Tower becomes your primary defensive anchor. A common mistake is scattering Bomb Towers across the map, which spreads their explosive impact too thin.
To maximize their utility, you should cluster your heavy ordnance at critical intersections or U-turns where bloons are forced to bunch up. Upgrading a Bomb Tower to a 2-3 Cluster Bomb configuration turns it into an incredibly effective crowd-control tool. The initial blast fractures the lead and ceramic layers, while the secondary explosions shred the tightly packed bloons underneath. Placing these towers within the radius of a 2-2 Monkey Village ensures they attack fast enough to clear out massive rushes before the bloons can separate and overwhelm your single-target defenses further down the line.
Round 46 introduces the first massive spike in difficulty by sending a single Massive Ornary Air Blimp directly down the track. If you are unprepared, this blimp will sail past your early-game towers without taking meaningful damage. To counter this without draining your bank account, you need to combine targeted single-target damage with a way to clean up the ceramic bloons inside.
If the map features water, placing a 2-3 Monkey Sub is one of the most cost-effective solutions available, using its high armor-piercing damage to melt the outer shell instantly. On entirely dry maps, your best approach is deploying a 2-3 Sniper Monkey set specifically to strong, paired with a 0-3 Super Monkey positioned under a 2-2 Monkey Village. The Sniper chips away at the blimp from long range, allowing the high-velocity plasma projectiles from the Super Monkey to shred the blimp the moment it enters the main defensive zone, ensuring the inner bloons never have a chance to scatter.
To beat this rush using nothing but raw game mechanics, you need a precise combination of stalling power and area-of-effect damage. Position a 4-2 Bloonchipper at the very front of your defense and set its targeting to strong. The vacuum will instantly suck in the leading Ceramics, breaking them down before they can regenerate their layers. Directly behind the Chipper, place a 4-2 Ice Monkey and a 4-2 Glue Gunner. The Ice Monkey permanently freezes the incoming clusters in place, while the Corrosive Glue liquefies the regrow layers all at once. This combination completely stops the regrow mechanic from triggering, keeping the rush under control so your primary damage dealers can clean up the remnants easily.
Once you break the back of Round 76, your focus must immediately shift to preparing for the final onslaught that ends on Round 85. The cash generated by your 4-2 Banana Factories should now be funneled into building a high-tier offensive setup. This is the ideal time to sacrifice your accumulated defenses to construct a Monkey Temple, ensuring it is fully powered by sacrificing at least thirty thousand dollars worth of Magic, Ice, Glue, and Bomb towers.
If the map is too small or lacks the space to build a proper Temple safely, you can create a highly effective alternative by spamming 2-4 First Strike Capability Monkey Subs or building multiple 4-2 paths for your remaining primary towers. Maintaining a continuous cycle of slowing abilities, armor-shredding damage, and high-impact area attacks will allow you to glide through the final rounds, taking down the massive ZOMG blimp on Round 85 and securing a clean victory on Hard Mode.
