Monkey Knowledge
Come On Everybody!
Come On Everybody! in BTD6: Primary towers attack 5% faster while all are below tier 3, or upgrade 5% cheaper while all are tier 3 or 4.
Primary towers attack 5% faster if all are below tier 3, and cost 5% less if all are tier 3 or 4.
Guide
Come On Everybody! is a fifth-row Primary knowledge with a conditional bonus for all Primary towers. If every Primary tower you own is below tier 3, they all attack about 5% faster (5% shorter cooldown). If every Primary tower you own is at tier 3 or 4, all their upgrades cost 5% less. You need 10 Knowledge Points in the Primary tree, Master Double Cross and a one-time 500 Monkey Money. It unlocks Bonus Monkey!.
How it changes the game
The two bonuses are mutually exclusive, and both depend on all your Primary towers meeting the condition:
- Early game (speed bonus): while your Dart Monkeys, Boomerangs, Tacks and other Primary towers are all at tier 0 to 2, they attack roughly 5.3% faster. That is a nice boost in the first 20 to 30 rounds.
- Mid game (discount): once every Primary tower is at tier 3 or 4, their upgrades are 5% cheaper. Because buying a tier 3 requires a tier 2 tower on the field, the tier 3 purchase itself can never be discounted. Tier 4 purchases can be.
- Tier 5 breaks it. Owning any tier 5 Primary tower removes both bonuses. Your first Primary tier 5 can still be bought at the discount, but only that one.
A single 0-0-0 Dart Monkey left on the map when the rest of your Primary towers are at tier 3 cancels the discount. Mixed setups get nothing. Non-Primary towers do not count toward or against the condition. In Co-op, each player's bonus is based on their own towers.
Is it worth it?
Priority: good, mainly as a gateway. The effect is real but fiddly, and many strategies naturally break the condition. Planned builds, such as a Primary Only run where you push several towers to tier 3 and 4 together, or an early game of low-tier Primary spam, get the most out of it. Selling a stray low-tier tower before buying tier 4s is a simple way to keep the discount.
The main reason to buy it is that Bonus Monkey! and More Cash sit below it. Since version 30, Come On Everybody! comes before Bonus Monkey! in the tree, so every player who wants the free Dart Monkey or the extra starting cash must buy it first.
Where it works
Come On Everybody! is active wherever Monkey Knowledge is enabled, including Impoppable, Primary Only, Races and Boss Events. It is disabled in CHIMPS and in challenges that switch knowledge off.
Frequently asked questions
What does Come On Everybody! do?
All Primary towers attack about 5% faster while they are all below tier 3, and their upgrades cost 5% less while they are all tier 3 or 4.
Can both bonuses be active at once?
No. The conditions exclude each other, and mixed setups get no bonus at all.
Does a tier 5 Primary tower cancel it?
Yes. Owning any Primary tier 5 removes both bonuses.
Why can't I get the discount on tier 3 upgrades?
Buying a tier 3 means that tower is still at tier 2, which breaks the all tier 3 or 4 condition.
Do I need Come On Everybody! for Bonus Monkey!?
Yes. Since version 30, Bonus Monkey! requires it.
