The Buccaneer is an 'interdictor'. What sort of unique traits/equipment are being brought to the table to fulfill that role?

At the core, its speed, maneuverability, and stopping power bring most of the interdiction potential of the Buccaneer. Along with that, we're still developing out the full scope for more equipment-driven Interdiction gameplay and how you'll be able to interact with other targets travelling at Quantum/Jump speeds. Expect more details to come as these systems are fully mapped and ready for implementation.
