Apopalypse (BTD6): Difference between revisions

Each round generates by choosing a random set of "Bloon groups". In general, stronger Bloons can appear earlier than they can in the normal round set (for example, [[Lead Bloon (BTD6)|Lead Bloon]]s can appear as early as round 20 instead of 28), though there is no guarantee that any specific Bloon type will appear (outside of round 100, which only contains [[BAD (BTD6)|BAD]]s). The game uses a seed system capable of generating <math>2^{31}-2</math> possible combinations of Bloon groups, but events and custom challenges use a fixed seed, so they will always generate the same rounds for all players. It uses the same system as [[freeplay]] and generates rounds in the same way starting on round 141 (including rounds 163 and 263).

There are over 500 pre-defined Bloon groups that can appear in Apopalypse. Each group consists of a fixed amount of one Bloon type (which may or may not have [[Bloon Mod]]s), a duration that determines the time it takes for the first Bloon and last Bloon of the group to spawn (effectively defining the spacing between Bloons in the group), and a range of rounds it can appear on. There are some combinations of Bloon types and Bloon Mods that do not exist in any groups, such as Camo Zebras, meaning rounds will never generate with them. The table below shows a simplified list of which Bloon type and Bloon Mod combinations can appear on which rounds.
