~ In-game description of Apopalypse when game mode is played |

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 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. Most round-based items except Geraldo's Shop items in this mode do not have a round lifespan.
By default, victory on this game mode happens by popping all bloons spawned from Round 1 to Round 60; winning gives the victory screen but disables the Review Map option. 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 round displayed is the one in which all bloons from previous rounds have either been defeated or leaked; 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 what is listed and this comes with some interesting consequences, such as super ceramic bloons before round 81. The listed rounds should serve to be more of the 'typical' round that you would start to encounter these bloon types, though BFBs and ZOMGs can still spawn much later than that. In addition, since the round counter only shows the highest round that has been defeated alongside all the rounds before it, it is possible to beat round 2 bloons without round 1 and save the game, then once reloaded, the game will think the player still on round 1 and this can be done repeatedly to give infinite money. This also explains why the rounds can be 'skipped' in apopalypse - it is often noted when a high health bloon from several rounds before is finally defeated when the round number suddenly jumps. (e.g. Round 100 -> Round 103)
Instead of each individual bloon and properties being random, rounds are randomly made with preset bloon groups, which are sets of the same bloon type, with a specific count and spawn time, Most bloon groups are converted from the waves constituting the corresponding Standard round; for example, the round 24 camo green can be spotted alone, as well as the camo regrow greens from the normal round 36. Few are from Alternate Bloons Rounds too, such as the 10 regrow purples, 25 regrow whites, and 10 camo ceramics from round 55. In fact, Apopalypse constructs waves using a seed system of up to 2^31 - 2 different combinations. Full list of all the spawns that can be generated during rounds 1-99 can be found here.
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. For example, in game code ZOMGs could be spawn on rounds 61+, however they never spawn on rounds 61-71 due to budget restrictions.
The chart below is a list of the most important bloon type introductions. Bear in mind that you will not see all of these in one game and will take several games. Regardless, it is best to be prepared for these rushes ahead of time.

Round 141+ | Transitions to Regular Freeplay Rounds |
Here are the bloons that are able to spawn on rounds 81-140. Unlike standard rounds counterpart, Purples and Ceramics only spawn until round 120, instead of 129 in normal gameplay and Lead Bloons don't spawn at all past round 99 (aside from special round 163). Also a Fortified BAD doesn't appear on Round 140.
During Rounds 100-140, Apopalypse usually spawns more BADs than Normal Play but less BADs compared by Alternate Bloons Rounds.
- As many MOAB/BFB groups that added on lower rounds could be spawned until Round 99, which means rounds 81-99 mostly consists occasional ZOMGs and/or DDTs alongside many MOABs and BFBs.

Rounds from 1-50 are now generally shorter. (RBE budget cut by 40%)
Rounds from 51-80 have generally less dense bloon rushes.

- 23.0
Pressing "restart" now pops up the "deathly" game rules message

- 41.0
“ | A much requested change, Apopalypse Mode now grants end of round cash. We’ve agreed that start strategies can be too limiting, especially on harder maps, so this is intended to bring more variety back to the mode. | ” |
~ Ninja Kiwi |
Apopalypse Mode now grants end-of-round cash upon popping all waves of a round.
- 44.0
Rounds 101-140 in Apopalypse now have increased chance of DDTs and decreased chance of Purple Bloons and BADs to match with Standard and Alternate Bloons Rounds.

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. That's because even all bloons spawned on round 99 didn't fully popped, still it generates round 100 BAD right after full round 99 generations. If you don't pop every ZOMGs and DDTs from round 99 but pop a BAD from round 100, still the game defines that you beat round 100, grants you an insta-monkey.
- In BTD6, Camo Blue Bloons are the only type of Camo Bloon that will never spawn.
- Apopalypse are always set to use a specific seed in events that do use the mode, although this behavior has currently only been seen on Odyssey Mode and Contested Territory.
- The rarest bloon group to ever be seen in any game of apopalypse that is able to spawn are the 15 tight ceramics on round 48. It is the only round it can appear on and has a 0.07557% chance, or about a 1 in 1323 odds to do so in any game.
- On rounds 86-100, only Round 98 is unable to leak Fortified DDTs in any game mode except boss events or odysseys, as Fortified DDTs only spawn on rounds 86-96 in Apopalypse, and on ABR, Fortified DDTs spawn on rounds 97, 99, and 100 as Fortified BAD's children.
- In game code, Round 100's B.A.D. only consumes 1 RBE budget rather than its original value (50,300), which means this is a guaranteed B.A.D.
