About Swarm Surge
Swarm Surge is a free browser action roguelite on Weekly Arcade, inspired by Vampire Survivors and Brotato. Control a hero who auto-fires weapons while you focus on movement and upgrade decisions. Enemy swarms escalate from simple Crawlers to fast Rushers, armored Tanks, explosive Bombers, and invisible Phantoms. Named bosses with HP bars appear every 90 seconds. Each level-up presents three random upgrade choices from a pool of 12 weapons and 8 passives, with weapon evolution unlocks available when conditions are met. Score is calculated from kills, time survived, bosses defeated, and XP gems collected. Meta-progression unlocks additional starting weapons at score milestones. No ads, no downloads, no in-app purchases.
How to Play Swarm Surge
Move with WASD or Arrow Keys (desktop) or the virtual joystick (mobile). Your weapons fire automatically toward the nearest enemy - your only job is to move and pick upgrades. Defeated enemies drop XP gems. Walk near gems to collect them, filling your XP bar. Each level-up pauses the game and shows three upgrade choices: new weapons, passive boosts, or weapon evolutions. Survive as long as possible. Bosses arrive every 90 seconds. At 15 minutes The Reaper arrives - killing it is the only way to win a run.
Swarm Surge Tips and Strategy
- Keep moving - standing still lets enemies surround you. Circle-strafe around packs to stay ahead.
- XP gems are magnetic within 80px (more with Magnet Up upgrades) - you don't need to walk directly over them.
- At level-up, check if any upgrade completes a weapon evolution pair before picking a passive.
- The Swarm Queen spawns at 2 minutes and summons Crawlers on every hit - kite her away from gem clusters.
- Use your one free re-roll per run when all three upgrade choices are already maxed passives you don't need.
- The Daily Challenge is a 6-minute seeded run - everyone faces the same waves and mutators. Beat the day's par score to keep your streak alive.
Swarm Surge FAQ
Is Swarm Surge free to play?
Yes. Swarm Surge is 100% free on Weekly Arcade with zero ads, no in-app purchases, and no download required. Play instantly in any modern browser.
How is Swarm Surge different from Vampire Survivors?
Swarm Surge is a browser-first version of the bullet-heaven genre - instant play with no download. Runs are won by surviving to the 15-minute mark and then killing The Reaper, which keeps sessions short enough for browser gaming contexts. It features a global daily leaderboard, achievement system, and cross-device cloud saves via Weekly Arcade accounts.
How does scoring work in Swarm Surge?
Score = Kill Points (5 per basic enemy, 500 per boss) + Time Bonus (1,000 per minute survived) + XP Gem Bonus (10 per gem collected) + optional 5,000 bonus for killing The Reaper.
Does Swarm Surge work on mobile?
Yes. Swarm Surge is designed mobile-first with a virtual joystick for movement. Weapons fire automatically so no tap-to-shoot is required. Performance mode auto-activates on mobile hardware.
How do I unlock new starting weapons?
Starting weapons unlock by reaching score milestones in a single run: Scatter Ring at 5,000 points, Blade Orbit at 15,000 points, and Chain Arc at 30,000 points. Unlocks persist across sessions via localStorage and cloud save.
What are weapon evolutions in Swarm Surge?
When a weapon reaches max level AND you own a specific passive upgrade, a weapon evolution card appears at the next level-up. Evolutions replace the base weapon with a dramatically stronger version. Up to 2 evolutions can be active in a single run.
What is the Swarm Surge Daily Challenge?
Every day at midnight UTC, a new 6-minute seeded challenge begins: every player faces the identical spawn waves, upgrade offers, and 1-2 named mutators like Boss Rush or Glass Cannon. Beat the day's par score to earn streak credit, with achievements at 3, 7, and 30 consecutive days. Daily scores compete on their own leaderboard with unlimited attempts - your best counts.
