Weekly Events
Arms Race
WeeklyA solo leaderboard event scored by growing your overall power — training troops, upgrading buildings, crafting gear, leveling heroes, and using speedups all count. Each day within the event highlights a different focus with bonus points attached. Save up speedups, training orders, and building materials beforehand, then burn them in a concentrated push once the event opens rather than spending steadily beforehand.
VS (Alliance Duel)
WeeklyAllianceA 6-day themed alliance-vs-alliance event with a different focus each day. See Alliance for the ranks and tech involved — a full day-by-day breakdown lives in Advanced Data once that page is built out.
Alliance Exercise (Marshal's Guard)
Every 2-3 daysAllianceA 30-minute alliance rally event: destroy 5 armored tanks together before time runs out. Only 3-minute rallies count toward damage — solo attacks and 1-minute rallies do nothing. If you've only got one strong squad, join others' rallies rather than leading your own. See Alliance for the full rules and Alliance Strategy for member tips.
Ghost Ops
WeeklyFarms rare hero shards that aren't available through the Tavern at all, split into SSR, UR, and UR* mission tiers. This is one of the only ways to fill gaps in your roster for specific hard-to-get heroes, so it's worth checking even if you're not actively pushing other systems that week.
Wanted: Code 39 / 64 / 87
Daily/Weekly rotationA rotating world boss fight — the specific troop type it's weak against changes by day, and damage is scored in a short window (commonly cited as around 90 seconds) once the boss spawns. Rewards scale with total damage dealt, so bringing your strongest available squad for that day's boss matters more than showing up underprepared.
Bi-Weekly Events
General's Trial
Bi-weeklyA wave-based challenge against Vanguard Instructor bosses, with a difficulty level you choose yourself. Lower time commitment than most major events, but a solid source of Skill Medals and hero shards — worth doing even as a lighter, lower-priority activity most weeks.
Zombie Invasion (Golden Zombies)
Bi-weekly, 3-day windowAllianceWidely cited as the single highest gold-yield event in the game — alliances farm zombies and rally Bosses together for Courage Medals, spent at a dedicated event store. See Additional Challenges for the full mechanics, rewards, and strategy.
Monthly Events
Glittering Market
MonthlyA rotating high-value shop where event-specific currency buys Legendary Hero Fragments, Mythic Gear Blueprints, exclusive skins, and permanent stat boosts. Evaluate long-term value before spending here rather than buying on impulse — not everything in the rotation is worth the currency it costs.
Zombie Siege
MonthlyAllianceA smaller-scale alliance defense event, similar in spirit to Zombie Invasion but scaled down. Upgrade your Wall and maximize Hospital capacity beforehand, and assign your strongest defensive heroes ahead of time rather than scrambling once waves begin.
Rotating PvP Battlefield Events
Storm Battlefields (Desert / Winter / Canyon)
Rotating, ~weeklyThese share the same core mechanic under different seasonal skins — large-scale 5v5-style combat centered on capturing and holding a Nuclear Silo, with weekly Honor Points (commonly cited around 10,000) rewarded toward Legendary gear. Since they're mechanically the same event reskinned, strategy that works in one (a well-timed teleport into contested territory, for example) generally carries over to the others.
City Clash / Warzone Duel
RotatingAllianceLarge-scale territorial PvP focused on capturing and holding cities or strongholds. See Alliance for the territory mechanics (flags, turrets, fortress) that underpin these events.
Meteorite Iron War
Inter-seasonAn inter-season PvP event centered on gathering Meteorite Iron, Crystals, and Stellar Cores from a shared Contaminated Land zone. Shield timing matters more here than in most events — plan when your protective shield is active around your gathering trips rather than leaving it uncoordinated.
