Choose the mode for the goal
Campaign’s thirty designed levels introduce scenarios in a controlled order, making it the best place to learn. Endless uses procedurally generated waves and tests whether the team can transfer its communication rules to new combinations.
Custom is the practice laboratory. Adjust bomb difficulty, timer, modules, hazards, and allowed mistakes to isolate one weakness. Change one variable per session; reducing every pressure source at once makes it harder to tell which communication improvement actually worked.
