Crazy Joe
Crazy Joe is one important source for Chief Gear materials:

How To Maximize Points
In Crazy Joe you can score two types of points:
- City Defense Points: These points only the owner of the attacked city gets. They are double the points that can be achieved by killing troops.
- Kill Points: You get points for killing the troops of Crazy Joe in every attack wave.
The maximum City Defense Points is the double of the maximum Kill Points you can achieve per wave. Here for example @chmul is only reinforced by @No_va. Nova is strong enough to defend a city for nearly all waves of Crazy Joe:

chmul receives 64,380 points because his city survived. Nova receives 32,190 points for killing all troops of Crazy Joe. The amount of points differs between the waves.
To maximize the points you get there is a strategy: Zero Defense. This does not mean that you are not defending against Crazy Joe, but that you do not defend your own city. Your own city is defended fully by your alliance members. Your goal is:
- Send out all your troops to other players!
- Reinforce players with little reinforcements to make the most kills!
- Do not take reinforcements from more than 3 other players. They have to share the kills and the points that can be made at your city.
- Do not send out your strongest heros! They need to stay on the wall of your city.
This requires a lot of organization. Start early to talk to your alliance friends who will reinforce who. Tip: It is easiest if you talk to people that have the same level of power as you have.

Special Waves
In wave 10 and 20 Crazy Joe will attack the Tundra Alliance Headquarter. In these waves you want to send troops to the headquarter to score points there. Please only send the announced amount of troops to give as many players as possible a chance to get a seat in the garrison. The amount of troops that is announced depends on the rally capacity of the strong player who will lead the defense. The garrison can fit a maximum of 15 players.
- Use Patrick as the leading hero!
- Only send the announced amount of troops.
- Send more infantry than lancers or marksman to score more points.
