Editing Spawn Mechanics (section)

== Spawn Types ==

==== Static Spawns ====
These are the guards of points of interest, locations, and objectives. You won't be able to prevent them as they exist before you even arrive.

=== Reinforcement Spawns ===
Displayed in-game as ''Bot Drop Detected'', ''Bug Breach Detected'' or ''Illuminate Ships Incoming''; one or more [[Dropship]]s fly in and drop bots, or one or more (indestructible, temporary) Bug Holes open up and release hordes of bugs from the ground, or one or more [[Warp Ship]]s in {{Illuminate}} ships incoming.

Reinforcement spawns are triggered by an enemy unit launching a signal through various means. The enemy reinforcements will then arrive about 10 seconds later, a few meters away from the signaling unit. The number of reinforcements varies within difficulty. Killing or staggering enemies before they can launch a signal can prevent reinforcement spawns, and so in theory an extremely attentive Helldiver team can prevent Reinforcements entirely.

Only one enemy-signaled reinforcement can be happening on the map at a time, and there is a roughly 2-5 minute map-wide cooldown (depending on Helldiver count and mission difficulty) between when signaled reinforcements can spawn. This cooldown time can be further increased with the [[Boosters|Localization Confusion Booster]].

==== Bug Breach ====
When a unit from the {{Terminids}} spots a {{Helldivers|Helldiver}}, they may response by raising their heads to emit a pheromone signal. A large, indestructible Bug Hole will appear close to the proximity of the pheromone, summoning hordes of Terminid. Bug Breaches are usually called by a [[Scavenger]], although other Terminids are also able to do so, as listed below:

* [[Spore Burst Scavenger]]
* [[Bile Spitter]]
* [[Pouncer]]
* [[Hunter]]
** [[Predator Hunter]]
** [[Spore Burst Hunter]]
* [[Warrior]]
** [[Bile Warrior]]
** [[Alpha Warrior]]
** [[Spore Burst Warrior]]
* [[Hive Guard]]
* [[Brood Commander]]
** [[Alpha Commander]]

==== Bot Drop ====
{{Automatons|Automaton}} Bot Drop occurs when either an Automaton [[Trooper]] or a [[Commissar]] launches a signal flare to the skies upon spotting the presence of a {{Helldivers|Helldiver}}. Within moments, a [[Dropship]] will arrive to dispatch Automaton units. The Dropships can be destroyed to crush the Automaton troops summoned.

==== Illuminate Ships ====
{{Illuminate}} Ships occur when a {{Helldivers|Helldiver}} is spotted by a [[Watcher]]. The Watcher will begin shining its light purple before emitting a beam of orbs into the sky. Within several seconds, [[Warp Ship]]s will descend from the skies to call forth reinforcements. Like the Bot Drop, {{Illuminate}} Ships can be destroyed to prevent them from summoning troops completely.

So far, Watchers are the only {{Illuminate}} unit capable of summoning reinforcements.

=== Objective Reinforcement Spawns ===
Certain [[Objectives]] will also trigger periodic guaranteed Reinforcement spawns. These spawns also arrive via Bot Drop, Bug Breach or Illuminate Ships, however they occur independent of signaled reinforcement spawns and are not affected by the cooldown.

* A Helldiver is spotted by the beam of a [[Detector Tower]]. This spawn can be re-triggered as soon as the previous wave of dropships leaves the map, meaning Detector Towers can very rapidly result in very large armies of reinforcing bots; however it can be prevented by evading or taking cover from the direct gaze of the Tower or simply using Stratagems to destroy the Detective Tower completely.
* The Factory Strider from the [[Factory Strider Convoy]] can summon Bot Drops upon detecting the presence of a Helldiver.
* A Helldiver activates a Probe or Drill during a [[Conduct Geological Survey]] mission. Triggers once per probe or drill activation (meaning 3 waves during the final drill site).
* A Helldiver attempts to raise a flag during [[Spread Democracy]] mission.
* A Helldiver activates a Nursery Chamber Drill during a [[Nuke Nursery]] mission. Triggers once the terminal of the drill has been activated.
* Frequently and regularly during [[Eradicate]] and [[Evacuate High-Value Assets]] missions. Triggers roughly once per minute, until the mission primary objective is completed.

=== Spawner Structures ===
Some enemy structures are capable of endlessly spawning troops until destroyed. Unless they encounter a Helldiver, they will remain in position. No data is available yet on how they function throughout the duration of a mission when Helldivers are not present in their vicinity. The presence of Helldivers within their vicinity do trigger unit production. Engage quickly and precisely to prevent being overrun.

The following structures are able to spawn enemy troops:
* [[Terminid Nest|Bug Hole]]
* [[Automaton Fabricator]]
** [[Bulk Fabricator]]
* [[Warp Ship]]

=== Patrols ===
A group of enemies that arrive on the map that will then have a designated path to walk. They often will spawn deliberately to cross a players path. They are the spawns that many players are decrying as unfair as they will literally appear out of thin air on top of them.
