Diamonds

Diamonds or jewels are the currency of the game. Almost everything can be accomplished if you are willing to use your diamonds for that purpose.

You can obtain diamonds in several ways. The accomplishments in the commander’s area pay in diamonds. Rewards for winning activities often include diamonds. The shooting gallery can award diamonds.

Diamonds can be mined in the territory outside the city. Or, you can spend real world money and buy diamonds.

It is not easy to accumulate a supply of the jewels. Mining them is slow, with a fixed rate of three per hour. There are ways to speed that up some but it is still hours to obtain less than 100 gems.

The shooting gallery can provide diamonds, under targets, at random. These are usually 10 or 20 at a time.

Being a part of winning an activity is often the best way to get diamonds. Whether it is the Single Player Arms Race, Zombie Siege or a Cross State Battle, winning results in rewards that often include diamonds.

Shields

Shields are also called bubbles. There are available in three time lengths, eight hours, 24 hours, and three days (72 hours).

Shields protect your city from attack by other players. They do not protect your troops who may be out of the city, farming a resource plot or camping.

While your shield is in place, you can attack zombies in the surrounding territory. You cannot scout or attack another player without dropping your shield.

A shield is useless in preventing zombie attacks during the Zombie Siege activity.

Activities

One of the best ways to earn additional resources and other benefits is to participate in activities. One of the buildings included in a new city is the activities building, and it is located just to the left of the citadel, and appears to sparkle.

The menu tells you which activities are currently in effect and when new activities will be available. Some activities do not require you to activate them. The Zombie Siege activity requires an alliance member to activate it. Warning - the loss of troops in an alliance that is unprepared for the Siege activity can be crippling.

Clicking on an activity that is underway reveals several things including your current score, your alliance’s current score, and a list of actions that earn a score. The rewards for meeting benchmark scores can also be seen by clicking on the packages.

The actions necessary to score a variety of points in that activity will also be displayed. It may be a short list of items, or a very long one. It may call for combat, or building, or spending resources and diamonds.
