- Survive The Swarm raids are the timed Swarm and Boss Events that cap each 15-minute run
- Squad synergy matters more than any single unit — build around elemental counters

- Best prep: unlock squad-wide damage and cooldown upgrades before pushing harder raids
What Are Survive The Swarm Raids?
In Survive The Swarm, a tactical bullet-hell roguelite from the solarpunk exterminator squad, every 15-minute run is broken into timed phases. The phases players call "raids" are the Swarm Events and Boss Events — the pressure spikes that determine whether your squad survives to the end of the run. Between these events you explore the map, grab upgrades, and answer randomized challenges, but the raids are where builds are truly tested.
Each run follows the same broad rhythm:
| Phase | Type | Purpose |
|---|---|---|
| Quest Event | Timed objective | Grants squad bonuses and resources |
| Recruit Event | Roster building | Adds a new exterminator mid-run |
| Swarm Event | Combat spike | Overwhelming insect waves from all directions |
| Boss Event | Combat spike | Fearsome boss that counters sloppy positioning |
Raids are timed, not wave-counted. Watch the phase timer and finish your shopping, recruiting, and upgrading before the Swarm Event banner drops — you rarely have time to fix a bad build mid-raid.
Because the swarm's threats evolve over the course of a run, a squad that cruised through early Quest Events can get shredded in a late Boss Event. Adaptability is the core skill this game rewards.
Building a Raid-Ready Squad
The roster includes 12 unique exterminators, each aligned with one of four elemental powers — Fire, Ice, Lightning, or Poison — and each with a distinct playstyle. Squad synergy is the difference between a wipe and a clear.
Speed Builds
- Kiting-focused units like Blaze's longbow
- Great for Swarm Events
- Weak if pinned by boss arenas
Area Control Builds
- Ice and Poison affinities
- Slow, choke, and zone the swarm
- Strong sustained clear rates
Brute Force Builds
- Isla's crushing hammer archetype
- Burst down Boss Events fast
- Needs support against massed waves
| Role | Best Raid Type | Elemental Pick | Key Strength |
|---|---|---|---|
| Striker | Boss Event | Fire / Lightning | Single-target burst |
| Controller | Swarm Event | Ice / Poison | Crowd lockdown |
| Support | Both | Any | Bonuses and cooldown relief |
| Flex Recruit | Late run | Counter-pick | Patches roster gaps |
Matching four units of the same element makes your squad brittle when the swarm's evolving threats resist it. Aim for at least two elements represented before the first Boss Event.
Characters unlock new abilities as they gain experience during runs, so a unit that felt weak early can become a raid cornerstone once leveled. Experiment deliberately — mastery of individual exterminators is only half the challenge.
Raid Execution: Step-by-Step
Follow this loop every run to convert a decent squad into a raid-clearing machine.
Open With a Quest Event
Prioritize timed Quest Events early. The squad bonuses they grant compound across the whole run and fund your first mid-run decisions.
Recruit to Cover Weaknesses
Use Recruit Events to counter-pick. Facing a fast boss? Add lockdown. Drowning in small bugs? Add area control. Recruit for the raid you expect, not the fight you just won.
Upgrade Before the Swarm Event
Spend map pickups and upgrades before the banner drops. Cooldown reduction and movement speed are the safest generic picks for raid survival.
Spread Formation in Swarm Events
Bugs swarm from every direction. Keep units spaced so area damage doesn't hit your whole squad at once, and rotate your controller to whichever flank is thickest.
Focus Fire in Boss Events
Identify the boss's biggest threat pattern, assign your striker to it, and let controllers suppress adds. Win or lose, you bank Honor Points either way.
Victory isn't just measured by completing a run. You earn Honor Points whether you win or lose, so even a failed raid pushes your account forward.
Honor Points and Meta-Upgrades
Honor Points are the persistent progression currency in Survive The Swarm, spent on upgrades that apply across your entire squad: increased damage output, faster movement, or reduced cooldowns. Smart spending order matters when preparing for harder raids.
| Upgrade | Raid Impact | Priority |
|---|---|---|
| Damage output | Faster boss kills, quicker swarm clears | ★★★★★ |
| Cooldown reduction | More ability uptime during spikes | ★★★★ |
| Movement speed | Escape surrounds, reposition in Swarm Events | ★★★★ |
| Utility bonuses | Situational, quest-dependent | ★★★ |

Raid Prep Checklist:
- Unlock squad-wide damage meta-upgrade
- Learn two exterminators per elemental affinity
- Practice rotating formation during Swarm Events
- Complete a full 15-minute run without losing a recruit
- Clear one Boss Event using a counter-picked roster
Common Raid Mistakes
Dumping every upgrade into one carry unit before the first Boss Event backfires when the boss's threat pattern counters that unit. Spread early investment, specialize late.
The mistakes that end runs fastest:
- Ignoring Recruit Events — a smaller squad means less damage and fewer ability rotations during raids
- Fighting the swarm head-on — bullet-hell spacing exists for a reason; kite and funnel
- Skipping Quest Events — those squad bonuses are your economy
- One-element rosters — brittle against the swarm's evolving, resisting threats
FAQ
Q: How long do Survive The Swarm raids last?
A full run is 15 minutes of high-octane action broken into timed phases. Swarm and Boss Events are shorter pressure spikes within that window, alternating with Quest and Recruit Events.
Q: Do I lose progress if I fail a raid?
No. You earn Honor Points whether you win or lose a run. Those points fund persistent squad-wide meta-upgrades such as increased damage, faster movement, or reduced cooldowns.
Q: How many characters can I bring to a raid?
You assemble a custom squad from a roster of 12 unique exterminators, and you can recruit additional members mid-run at Recruit Events to bolster your ranks before Swarm and Boss Events.
Q: What is the best squad composition for Boss Events?
There is no single answer, but a strong core pairs a high-burst striker such as a Fire or Lightning unit with an Ice or Poison controller for adds, plus a flexible fourth slot counter-picked at the last Recruit Event.
