Base PvP (raiding) becomes available at level 15 and allows players to attack enemy bases (or have their bases be attacked if they don't have an active peace shield) .

For cracking/ breaking enemy bases (destroying docked ships, shields, and defense platforms), it's best to consider the power of the ship divided by its repair cost. Cracking a base can take 100 hits or more to open it up for raiding completely, so choose wisely when selecting your ship. A ship that can do comparable damage with a lower repair cost may be more efficient.
