Combat Simulations: Construction*, Atrium, Cafe, Complex*, Supply Depot*, Front Yard, Loading Bay, Office Lanes, Reactor, Reactor Hall*, Server Room*, Underground Base*, Legacy Horde 1* (21st wave features 'Funny Man'), Legacy Horde 2, Waiting Room.

Sims Labelled with * have Classic Jigglies on their Wave 13 and are equipped with weapons.

Every Rosters just about will heavily follow the format of the Horizon Roster, but they will most likely have different variations of units who may be armoured differently, have different health values, carry varying weapons or weapon attachments, or have waves where the Unit composition strays from the usual form.

For now this guide will treat the Horizon Roster as the default, and will address other Rosters as alterations of its format by explaining its features as differences via comparison.

Combat Simulations: Courtyard, Auditorium, Cavern, Cultist Courtyard, Dinner Time, Presentation, Study, Lit.

The Cultist Horde differs from the Horizon Roster the most. It may borrow slightly from it, but the Roster will offer a wider range of units amount and variation.

Keep in mind Cultists throw Fire Bombs, although if regular Guards spawn, they will use their own types of grenades.

Combat Simulations: Site 83 Hall*, Forklifts, The Shard, Arkansas*, Flip Tricks, Backrooms, Grounded.

Sims Labelled with * have very few of its Hazmat Units get switched out with a similarly equipped Horizon Unit within some of the waves. It's a very minor change, although Horizon Pistol & Shield Guards wear helmets, where the Hazmats Unit Variant do not.
These units will be marked with a * within the table.

The Hazmat horde has a much higher use of Laser Sights, but the composition of its Units are just about exactly the same.

Combat Simulations: Brutalism, Concert, Penthouse, Little Lobby.

Major differences include the Heavy Soldiers in Wave 16 and 19 being simply replaced by a mere single Shotgun Unit and Wave 19's Pistol Unit is now equipped with a DMR. While the FINAL! wave has a two of a new unit and has an entirely unique composition.

All Pistol, SMG, Shotgun, and DMR Guards are replaced with an equivalently armed LawyerThug. They do not wear helmets, do not use Laser Sights or significant attachments, and would have slightly different health values.

Combat Simulations: Oilrig, Crematory.

All Guards have been replaced with an HECU Guard Horde Equivalent where most noticeably DMR Guards are spawned instead of Penetrator Bolt Launcher Grunts, and The Regular SMG unit notably now dons a helmet, which could consider it's NVG (Night Vision Goggles) Upgraded/Armoured counterpart redundant, though it can be shot under just like an Evil Mercenary and his helmet. Yet similarly to the Evil Mercenaries, the Pistol & Shield Units are also for some reason Horizon Guards and not an HECU Grunt equivalent.

The HECU Grunt horde are never equipped with laser sights, while featuring the same Rifle Grunt throughout most waves. On Wave 18 they replace their capable helmet donning SMG Grunts with unarmoured SMG Hard Hat HECU Workers, whose helmets are far more suited for Work Health and Safety Than bullets, consider them cosmetic.

Other than these mixes, The composition and unit distribution are exactly the same as the Horizon Roster

Combat Simulations: Cryo Chamber, Nuke.

Most Regular Guards have been replaced with Evil Mercenaries who don red visors. This helmet will cover the top of their head, but with good aim it can be shot under by targeting the lower half of their head. They may also have higher health values than their Horizon counterparts.

This Horde tend to use silencers instead of laser sights, and have enlisted Pistol & Shield units from Horizon spite having their own existing ingame Opfor 27 Pistol & Shield Unit. There is also a difference in unit ratio in wave 14.

Combat Simulations: Miracle Water, Heat Sink, Site 44, Dry Docks, Cargo Wing, Crossroads, Skylight, Excavation Point, Hideout.

From the first wave, Units wear helmets, and more effective weaponry appear much sooner than prior Hordes. Majority of the Units within these hordes are exclusively found within the Bladekisser DLC missions.

This Roster is vastly different than any other Roster before it, it has an entirely new layout, and there are none of the usual staple rounds such as the black ops rounds, single heavy soldier wave 11 round, jiggly bois round, etc, any prior knowledge goes out the window here.

There is also a random element within this roster. Some waves will feature Units with or without helmets, regardless of their weaponry loadout. And within some waves, Units may be equipped with a Pistol or Revolver, or some Units may be equipped with rather an SMG or Machine Gun.

Regular "Amnesty" Units have a high variety in worn Armour and Helmets, to avoid lengthy bloat I've decided to not list a further exact Unit desciption, only list their weapon equipped, and lack of helmet notes where I can.
Although as a rule of thumb, if they have a gas mask, they will possess some armour.

The first 20 Waves will follow the location's Horde Roster. (listed above)

All waves past 20 no longer follow a set Roster, Instead a random Draft is created from a list of possible Units to create a Team of 20.

Units will have different weights for spawning frequency, regular Combat Sim Roster defining Units such as Guards and Hazmats spawn more often than the few Heavies, Black Ops, and Evil Mercenaries that may feature within a Wave's Draft.

These are the possible unit spawns for each Roster, not listed in any particular order of weight or apperance:

Within the 5 Waves of a Map, the chosen Faction will have Draft possible Units and a range of the amount of spawned Units depending on the selected Difficulty Level. Units will also have different weights of spawning frequency from eachother.

Beginning Waves will more likely spawn an amount near the low point of the possible Spawn amount, and the ending Waves will likely spawn an amount closer to the high point.

With my data, There may be a 1-2 Unit imprecision to the maximum or minimum amount of Units spawned in a Wave. I noted down the amounts as much as I could but to 100% guarantee these numbers would take much too long.
Beginning waves will tend to spawn an amount near the low point, and the ending waves will spawn closer to the high point

The units tabled here are not listed in any particular order

*The bodyguards here are Units From the Horizon Bodyguards Faction

These Wave Rosters are the same no matter the map or difficulty, and feature a large range of High Value Targets. I've left short notes about each HVT who appears for slight quality of life.
