All games Left to Survive In-game issues

I have a question about Base Raid (helicopter mode)

Base Raid is the helicopter combat mode in which player attacks bases of other players. If the attack is successful, player gets a share of Oil and Materials stored on the opponent’s base.

To perform a successful attack, player must demolish a large portion of enemy buildings, destroy the Town Center, or level the whole base.

The Town Center is shielded against attacks at the start of Base Raids. To deal full damage to the Town Center, destroy all defensive towers, or bypass them.
