Across a Million Worlds, We March

Drown the opponent in expendable bodies, then follow up with the Terror Tank — a mobile fortress that reconfigures as the fight changes. You trade units freely and win by never letting the enemy reset.

Who they are

The Legion of Truth are a fanatical empire from beyond known space, sworn to their Emperor and a pantheon of god-like Idals. Their armies crusade across the cosmos, bringing everything in their path under the Idals and purging whatever refuses the voice.

Playstyle

How they actually win

By never letting you reset. Thralls and Fanatics are expendable by design, which means the Legion can keep contact in situations where another faction would have to disengage and rebuild. Behind that wave comes the Terror Tank — a mobile fortress that reconfigures as the battle changes.

What to expect fighting them

Constant pressure and unfavourable trades that still somehow work out for them. Splitting a Legion army from its reinforcement flow matters more than winning any single engagement.

Should you pick them?

Pick them if

You want to be the one applying pressure from the first engagement onward.

Look elsewhere if

You dislike losing units. The Legion's whole economy of play assumes you will.

The other three

Protectorate armour column and walkers advancing across a shallow riverbed

ProtectorateA Caelo Ad Terram

The most conventional army in the game. Infantry, armour and air that all behave the way an RTS player expects, with siege-style firepower to punish a static defence.

Grell biomass spreading across a field with plant-creature units massing on it

GrellGrow. Expand. Exterminate.

You expand by spreading roots and biomass across the battlefield rather than just planting more bases. Territory is the resource; ceding ground costs you more than it costs other factions.

A dense sci-fi base laid out around a flux crystal formation

Xol BetaFor Purpose. For Survival.

The newest and least settled faction. Expect the most balance churn here — builds that work this patch may not survive the next.
