Apopalypse (BTD6)

Apopalypse is a gamemode in Bloons TD 6. It is unlocked after Military Monkeys Only is beaten for the specific track. On Apopalypse, bloons spawn in completely randomized waves with no break between them. When a round sends all its generated Bloons, the next round immediately begins, even when previous rounds' bloons may have not all been popped. There is no cash awarded after each round ends.

By default, victory on this game mode happens by popping all bloons spawned from Round 1 to Round 60. Unlike its BTD5 counterpart, the game starts as soon as player selects Play after being presented with a warning screen. This also applies to saved games.

Bloons spawning in BTD6
In Apopalypse, the displayed round is the round in which all bloons from that round have either been defeated or leaked and new rounds can be sent even if the previous round has not been sent or popped completely. Due to this, it is possible to see bloons appear on earlier rounds than listed.

Instead of each individual bloon and properties being random, rounds are randomly made with preset waves, which are sets of the same bloon type, with a specific count and spawn time, with some waves being from the Alternate Bloons Rounds or regular rounds; for example, the round 24 camo green can be spotted alone, as well as the camo regrow greens from the normal round 36.

Due to the higher RBE weighting of higher tier bloons they are also less likely to appear in lower rounds for some of the below bloon spawns.

Trivia

 * The name 'Apopalypse' is a portmanteau of the words apocalypse and pop.
 * In BTD6, prior to version 8.0, there was a bug where you could collect an insta-monkey when Round 100 started, without having to defeat the BAD. This bug was fixed in 8.0; now the BAD has to be fully popped in order to get the Instamonkey. In fact, it's now possible to earn it before even reaching Round 100.
 * In BTD6, Camo Blue Bloons are the only type of Camo Bloon that will never spawn.
 * Spike Factory's long life spikes are less useful as all Spike Factory Spikes last in between rounds. It should be in your best interest to only use Smart Spikes instead for extending the duration of them.
