The Orca is a Tier 6 ship in the Nautic Series mod. It fires high damage pulses from the front while dashing forward making it a very good ship for surprise attacks. When the energy is low is will only shoot lasers and will not dash. You may die if you use up your energy in combat.
It is somewhat similar to the Hammerhead Shark, but it is heavier (more knockback when ramming) and mines slower (less energy regen).
