You can win a shield in building contests, as a top wiki contributor, or for special other circumstances.

Building contests are rarely organized (and will become more and more rare). It's not known when the next contest will be. In a building contest you have to build something for a specific region or faction in a few weeks. The best builds will be rewarded.

At the end of every year, the top 5 (or top 10) wiki contributors (based on a list that Handles keeps updated) will get a shield.

Examples for the mentioned "other circumstances" are the discovery of a hard to find easter egg, doing something important for the mod, or being a member of the mod team.
