Twenty waves of bandits hit your alliance’s cities and HQ. It’s a defense event that rewards being online and reinforcing well.
TL;DR Stay online for the elite waves, defend Infantry-heavy, send strong players to the HQ for waves 10 and 20, and spread reinforcements instead of piling into one city.

Online members only
Elite waves worth about double points. Be logged in.
Per community wikis. One guide lists only waves 7 and 14 as online-focused. Waves 17–19 together are reported as about 31% of all available points.
🧮Scoring & rewards
Kills defending your own city earn full points. Kills made while reinforcing a teammate earn about 50%.
R4/R5 set the difficulty before it starts (one wiki lists 21 levels). Higher difficulty means more points and bigger rewards.
Rewards arrive the next day at 12:00 UTC, based on state-wide ranking. They include Chief Gear materials (Polishing Solution, Hardened Alloy, Design Plans) and speedups.
📜Rules worth knowing
Shields don’t work during Crazy Joe. You never lose resources, only troops.
A city that’s breached twice stops being attacked, but its owner can still score by reinforcing others.
Don’t move garrisoned troops until the event ends.
🎯Strategy
Defend Infantry first, Lancers second. Marksmen add little here.
Before it starts, reinforce online teammates, but don’t overcrowd one city: reinforcement points are shared by contribution.
Keep your strongest defense at home and put defensive heroes (Sergey, Patrick) in your garrison.
Send strong players to the HQ for waves 10 and 20 with the troop mix your R4/R5 announce. Leaders can release them after wave 10.
Push the highest difficulty your alliance can handle, and review results before raising it.
