The Bloons Tower Defense games are some of the most popular ever featured on this site. Ninjakiwi has come up with an expansion pack that is fun, challenging, intriguing, frustrating (in places), and guaranteed to suck you right back into the world of the Bloons (just when you thought you were out). Will this tide us over until Bloons Tower Defense 5 comes out? Maybe, maybe not. But it's definitely worth checking out, if only for the amusement of finding the super secret surprise.

Bloons Tower Defense 4 left a bad taste in my mouth because there were certain upgrades you could only get through Mochi coins, making it a rare Pay-to-Win Flash game. Other than that, the gameplay was fun. I just hate to see the trend continue.


The fast forward button works! Hallelujah!

i would have to disagree that this is a pay-to-win (except for me(i have terrible lag and it crashes at about level 70))it just requires heavy grinding, like ginormo sword


I feel myself being sucked in by a black hole. Or is that just Bloons Tower Defense 4 Expansion? I may never live to tell the tale.

So, I've encountered the Sun Temple secret - are there others?


For the secret:

On the temple level, you have to sacrafice $30,000 and 40 buildings then the temple starts killing everything. Make sure to havea lot of Bannana farms so that you can rebuild your structures.

Hahahahaha!!! Just reached round 100 on advanced map and then it crashed on me! All I've got now is a white screen with a ! in a circle.

Sorry for double post but I have some ideas for bloons tower defense 5:(Not actually a spoiler)

New bloons types:
Bronze (5 hits required before breaking, 5x faster than pink bloon, contains 2 pink) RBE: 16

Silver (20 hits required before breaking, 2x faster than bronze bloon, contains 2 bronze) RBE: 53

Gold (100 hits required before breaking, same speed as silver, contains 3 silver and 1 lead) RBE: 283

MLB (Microscopic lethal bloon) (1500 hits required before breaking, contains 5 BFBs, decently slow) RBE: 15921

New tower types:
Road spike factory. Makes 10 road spikes each round with every upgrade. Cost: 700

Pineapple thrower. Throws a pineapple every 3.5 seconds. Slow, can miss frequently. 4th upgrade, throws 5 pineapples at a time. Cost: 550

Grenade thrower. Throws a deadly grenade that strips 2 layers at a time. Very slow reload time; 5 seconds. 4th upgrade, grenade clusters, when one explodes, 4 other grenades pop out and explodes on impact. Cost: 1430

Railroad train. Placed on a road. The train moves across every 4 seconds squashing and popping bloons. Lasts when 500 bloons are popped. Cost: 120

Submarine. Placed only on water. Acts like a banana farm but the submarine collects treasures every 3 rounds and the amount depends on its level. 4th upgrade, collects a staggering 10000 money every 2 rounds. Cost: 3000

New difficulty level: Insane! 80 rounds to pass. 125% cost of towers on medium.

Money starting: 700, 500 on insane!
Life starting: 300 on easy, 250 on medium, 150 on hard, 50 on insane!

Miscellaneous upgrades
Road spikes pop 20 bloons and the cost is 40.
Super monkey storm reloads every 1 minute and 25 seconds. (In BTD4 it's 1min and 45 sec approx.)

Note: The costs of the new tower types are all on medium.

Sorry the spoiler is long.
