SWARMCAST game modes and battlefields
SWARMCAST has four missions with different pacing and objectives. Choose the mode first, then pick a battlefield: the mode sets the mission rules, while the map changes the environment around the fight.
Classic
Classic is the main wave-survival run. Fragments, formed enemies, and escalating species pressure share the arena; an Omega Colossus arrives every fifth wave. Use Classic to learn enemy silhouettes, test weapons, and build a run over time.
Good first choice: players learning how enemy fragments evolve. There is room to practice the core combat loop before specializing.
Zen Protocol
Zen moves at a calmer pace and continues after the operator goes down. It is useful for practicing movement, learning a battlefield, and experimenting with a loadout without ending the run on the first defeat.
Good choice: players who want a longer, lower-pressure run while they learn the systems.
Boss Rush
Boss Rush skips ambient fragment waves and sends Omega Colossus fights one after another. Later fights become tougher, so boss damage, lateral dodges, and attacking during recovery matter more than clearing ordinary enemies.
Good choice: players who already understand boss wind-ups and want a direct test of damage and dodging.
The Last Assembly
The Last Assembly is a ten-stage signature mission with changing objectives. Cut the swarm's supply, survive the Architect, ride the debris upward, and reach the core. Read each stage objective before spending an ability or committing to a route.
Good choice: players who want a directed mission with set-piece objectives instead of an endless wave climb.
Modes and battlefields are separate choices
The battlefield carousel changes where the run takes place; it does not change the mission mode. Classic Arena and Zen Sanctuary are the baseline arenas. Other locations add themed terrain and hazards, so read the map description before deploying. Ember Cathedral is the volcanic assembly core; other available locations include Singularity Abyss, Buried Engine Expanse, Stormforge Circuit, Verdant Maw, and Chroma Rain District.
Local co-op
Two-player local co-op is available for Classic and Zen. Both players share one screen, each has separate health and shield, and a standing player can revive a downed partner. Co-op is not a solo leaderboard run.
