What is the Shield? How does it work?

An active Shield protecting your base against other players's attacks.

Very important! You lose your Shield if you go to attack an opponent, while it's an active. However, campaign missions and searching for an opponent do not deactivate your Shield.

If your base was attacked and destroyed, you automatically receive a free Shield. The duration of the Shield depends on the base destruction degree: from 1 to 14 hours.
