New Factions

War of the chosen introduces a number of new factions. Some of them are friendly while some of them are enemies. We have explained in detail all new factions of the expansion below:

Enemy Factions

These factions are your enemies and you will have to battle them to survive. They are The Chosen and The Lost. ADVENT is not a new faction but they have acquired some new soldiers for their arsenal. We will talk about them as well in our guide.

The Chosen

The Chosen is an all-new enemy faction introduced in the expansion pack. They are pretty hard to kill and they deal a high level of damage to your team. If they appear once and you kill them, they will still keep on coming until you track down their Citadel and destroy their regeneration structure known as sarcophagus.

Each unit of The Chosen has different boss-like abilities and they will deal a lot of damage. They have no spawn pattern, they can show up at most random times and they can totally ruin your mission. They can also capture members of your team to interrogate them for the location of the Avenger. The Chosen are the hardest of all enemies that you will face in the expansion pack.


Though ADVENT is not a new faction, they have three new alien components so we will discuss them in this section. The new aliens to join ADVENT are Purifier, Priest and Spectre. Spectre is a sniper and boast stealth.

Spectres can disappear right in front of your eyes or they can even become shadow clones of your team members using Shadowblind ability. They can also heal themselves if they use their horror ability. They have lightning reflexes.

Priests are psychics of ADVENT. They use their psychic abilities to stun and disable your team members. They have a magnetic rifle and can use abilities such as mind control, Stasis or mind merge. Purifiers are heavy units and they carry flamethrowers. Their weapon has a very wide area spread, which cause fire to spread across a wide area. When they die, they explode dealing damage to nearby units.

The Lost

The last enemy faction is The Lost. They are mindless zombies attacking everything they see, alien or human. They attack in packs and they can easily desecrate anything in their path. Lost are attracted to loud noises and gunfire. When you see a pack of The Lost approaching, do not engage, run.

Attacking them and winning is very difficult because they overpower your tem very easily with their sheer numbers. You can divert The Lost to enemies to gain some competitive edge during battles.

Friendly Factions

These factions can become your allies if your win their allegiance. You can do various activities to earn these factions’ trust. You can then later work with them and get many benefits, which include special hero units that are highly effective on the battlefield. These hero units are Reapers, Templars and Skirmishers.

Reapers are stealth units and they are highly effective against the Chosen. Unlike traditional stealth units, they can go back to being stealth even after being detected by the enemies. They are excellent ambushers. Their sniper rifle is deadly and super accurate. They also have explosives such as Claymores and saboteur abilities, with the help of which they can self-destruct cars. With these abilities, they are excellent ambushers and long range damage dealers.

Templars are melee solders and they can gain power as you kill enemies. They are silent killers and every move is related to silently killing an enemy. They have ‘rend’ which increases the mobility and also gives them increased focus.

Last friendly faction are the skirmishers. They are former ADVENT soldiers and they want revenge from ADVENT for keeping them under their control. Templars are equipped with assault rifles and Ripjack melee weapon. They are also the most versatile of all the factions. For increased mobility, they also boast a grappling hook, which is excellent or getting behind enemy lines or flanking attacks.

Before you can get access to these heroes, you must complete their missions and covert ops to earn their trust. Earning trust is no easy feat. However, if you do manage to earn their trust, they will make it worth your while.

General Game Tips & Tricks

Covert Actions are non-combatant missions and they are a new feature added to the tactical layer. You must send soldiers on these missions to earn a lot of benefits. One of these benefits is that you may earn the respect of one of the friendly factions in the game. You will gain access to new resources, soldiers or even track down The Chosen Citadels to eliminate their presence in sectors.

Defeat Chosen Citadels to earn unique weapons. Depending on the type of class, you will earn a unique weapon for the so they should be your priority. Complete three covert action missions and you will unlock the location of a Chosen Citadel. Defeat it and you will get a unique weapon depending on the class.

Another new feature is the Soldier bond system. During battles, soldiers if they help each other during dire situations, they become bondmates and unlock new bonus skills, which are very useful in combat. You must try to use this feature as much as possible in the game.

Easy way to make bondmates is to use the same soldiers together repeatedly. More they fight together, more chances of them becoming bond mates. Send them together on missions to increase chances of survival.
