Faction Weaknesses

Corrosive against heavy armour; Viral + Heat is the practical all-rounder.

Magnetic for shields; Toxin bypasses shields and hits health.

Heat, Gas and Slash are strong against dense crowds.

Some units resist or are immune to Viral.

Viral/Corrosive is the balanced pick against mixed defences.

Carry several damage types together because of adaptation.

Toxin bypasses shields; Slash is another useful natural weakness.

Radiation stands out against many heavy Murmur targets.

Remember that Infested faction mods do not work on Techrot.

Corrosive support is valuable against armoured targets.
