Returning and new threats
The enemy fantasy is deliberately familiar: large waves, recognizable foes, and fresh monsters built to overwhelm the squad. This page stays at the verified overview level rather than inventing a complete bestiary.
Arena survival habits
Read the edges
Enemy pressure does not only come from what is directly in front of you. Keep an escape lane and track where the next wave can enter.
Control the crowd
In co-op, communicate the target that needs attention before everyone fires at a different problem.
Enemies and bosses
The five lieutenants are the major progression targets described by the official store page. Smaller enemies can still decide whether the squad reaches that encounter, so the two categories need to be planned together.
