As part of this years foundation festival free fly event you can try out any of the selected 12 highly detailed ships in the game absolutely free.
There is also a focus on helping new players with the guide system which pairs new and experienced players together to show them the ropes.
If you enjoy the experience and decide to buy the game (~$40USD) before the promotion ends, by signing up through this referral link both the referrer and the referee will receive a free Aopoa Nox to their account worth $45 USD. The referee will also receive an additional bonus of 5000 UEC (In-game currency) bound to their account for signing up through a referral link.
Once you have bought the game there are no monthly subscriptions needed, but be aware that this game is not yet complete and is still very much in development so there will be bugs, and your enjoyment of it will depend on your tolerance for them.
Fly safe!
