Slurp! Settling in at level 22 means resource management is key, hmm! You should wisely stockpile resources by conquering zombie lairs with your allies. What resource are you most lacking right now to reach level 23?

Attack empty houses (inactive players) on the server to get resources.

I'm level 28. First, you need to join a big alliance to be safe from raids. If you're aiming for hidden content, an older server is better than a new one, and it's best to gather large resource nodes. Joining a strong alliance means you can get carried (bus) by powerful players, making resource acquisition easy. So, the alliance is the most important thing.
