Runescape has been updated to bring RunePass - Ocean's Bounty into the game. The event will last for two weeks and will allow players to earn exclusive cosmetics just by playing. There are a number of challenges and tasks for players to complete throughout 30 tiers. The higher the tier, the more rewards are unlocked.
All players are able to progress along the free track and win the prizes listed there. As an addition, you are also able to purchase a Runepass for 400 RuneCoins. This gives access to two new task slots and to the golden track, which holds many more prizes. For purchasing the Runepass you'll even get two prizes immediately - the ocean's warrior head and the legendary Water Lycan pet.
You can check out the full details on the RuneScape site.
