Tutorial/The Mystical Waverider...

The Waverider is a very mysterious waterborne vehicle that can be summoned to its skipper's side using a Waverider Waypoint. Get close to the Waverider to board and set sail.
You can summon it from a Waverider Waypoint at any time, but one person can only own one Waverider.

Waveriders can Accelerate to increase their speed.
Waveriders are also armed with two different weapons: the Swiftstrike and Heavy Cannons. The Heavy Cannon has more firepower, but goes on cooldown after being fired.

Hold the Jump button to stop sailing and leave the Waverider.
After leaving your Waverider, you can get close to it again to start sailing or use a Waverider Waypoint to summon it to your side once more.
