In Cradle of Empires, you can invite friends to your team from the Friends tab in the Teams menu. Simply go to the Friends tab in the Teams menu, tap/click on the friend you'd like to invite, then tap/click "Send team invite". Your friend will see an invitation that they can accept or reject.
If you don't see the "Send Team invite" option, your friend might already be on your team!
PLEASE NOTE:
- Teams are open to all players at Level 11 and higher. Before inviting them, your friends need to reach this level.
- Cheaters may lose access to teams.
