Triggers

Triggers
Triggers are a game mechanic that is based on a certain condition such as crap patrol units or characters moving into a certain area or certain buildings being destroyed. Triggers are split into boss triggers and non-boss triggers.

Boss Triggers
(Information referenced from CP2 Wiki Boss Trigger Page)

Brutalisk Trigger
The brutalisk is triggered by destroying the hatchery to the left side of the first area.

Omegalisk Trigger
The omegalisk is triggered by crap patrol units or characters moving into the Omegalisk Lair.

Leviathan Trigger
The leviathan is triggered by crap patrol units or characters moving into the Leviathan Lair.

Brain Bug Trigger
The brain bug is triggered when crap patrol units or characters attack the brain bug.

Hybrid General Trigger
The hybrid general is triggered when characters blink, attack or nuke the high ground of the hybrid general lair. It is also triggered when crap patrol units or characters move into the hybrid general lair through the main entrance.

Waves of Ultralisks (First Area)
13 or 14 waves of 3-5 ultralisks in each, spawning near the Omegalisk Lair beyond the Roach Hill.

This wave is spawned by killing 5 out of the following 7 buildings: The hatchery north of the base, The greater spire, The lair, The other hatchery, The spore canon and spine crawler near the ramp, and the ultralisk cavern. The game checks every 15 second to see if this condition has been triggered or not.

Primal Ultralisks and Queens (Roach Hill)
7 or 8 primal ultralisks, 5 or 6 primal queens and some other primal units.

They are spawned as the players fight their way through the Roach Hill 1st high ground. Walking past a certain point on the hill will trigger them.

Roaches on the Roach Hill (Roach Hill)
Spawns several hundreds of roaches. The roaches are spawned once players have killed 5 out of 7 building/units. These seem to be The roach warren on the hill, the brutalisk, the hydralisk den and the evolution chamber towards the middle + some of the spore crawlers and one of the spine crawlers on top of the hill.

The game checks every 37 seconds to see if this condition has been met or not.

Primal Ultralisks (Ultralisk Sector)
5-6 Primal ultralisk will have a chance to spawn when you kill the following buildings: The 3 ultralisk caverns, the lair, the spore crawlers OR, very rarely, the spore cannon in front of levithan's entrance.

Mutalisk Waves (Mutalisk Sector)
Spawns tens of groups of 7-8 mutalisks.They are spawned in the top center of the Sector 2 as players kill the hatchery and start proceeding to the top towards the corridor leading to the Leviathan. Most characters are unable to tank the collective damage.

Death Wave (Hybrid General Lair)
More information can be found on the Death Wave page.

Activated at the same time the hybrid general is triggered.
