Space Marine 2 Siege Mode Wave Tips

Siege is about the gap, not the fight

The wave is the easy part. The time between waves is where Siege is won or lost, because that is when you buy upgrades, repair, and reposition. The siege mode page covers the structure; the habit is to treat the intermission as the main event. A squad that fights well but wastes the gap stalls out by wave ten. One that prepares stalls out never.

Heavy and Bulwark anchor the line

Siege funnels enemies into a defendable space, which makes the Heavy and Bulwark the backbone. The heavy class guide covers the damage hold; pair it with a Bulwark screen and the swarm has nowhere to go. Ranged classes thin from behind that wall. The team comps page applies here too, but the bias should lean defensive as waves scale.

Spend currency on what scales

Between waves you earn currency to upgrade. Prioritize upgrades that help the whole squad or that directly extend survival over niche perks. The mistake is spreading points across flavor instead of stacking the few upgrades that keep you alive another wave.

Know when to fall back

Siege rewards a fallback line when the current one is overrun. Do not die on a position you cannot hold. Retreat to the next defensible point as a squad, and the wave breaks itself on the new wall. Panic scattering is not a fallback. A coordinated move to a better angle is.
