How to Complete the Marine Fortress Secret Quests
The three secret quests in Marine Fortress are easy to complete, and the island is probably one of the easier ones, like Jungle Island. Let’s go through how to get all three stars quickly.
Secret #1

The secret can be uncovered once you enter the tower adjacent to the large central tower. To know which tower I’m talking about, you can refer to the image above. At the very top of the tower is a window you can enter to gain access to the inside. You can either get to the window by flying towards it or taking the ladder from the base of the tower.

Speak to Parlus inside the tower room, and he will give you the task to raise the flag. But the flag is missing its rope, so you need to find the rope first. The rope can be found lying on the ground at the outskirts of the island. From the tower, fly directly towards the trade stand and drop down; the rope is quite easy to find. I’ve even marked the exact location on the image above so you can’t miss it.
Now you need to find the flagpole and get the flag hoisted. The flagpole is right next to the Quest Giver NPC, close to where you picked up the rope. Interact with the flagpole and hoist the flag, then return to Parlus to complete the quest and get 4x Level Ups.
Secret #2

The next task is quite easy to do but will take a bit of waiting around. All you need to do is wait for the ships to appear around the island, then use the turrets on the island to shoot them down. The Ships appear every hour, and you can speak to Parlus to find out when they appear.
I would suggest just attacking them using your skills so it’s easier to take down all the ships quickly. Speak to Parlus after clearing out the ships to complete this quest and gain another 4x Level Ups.
Secret #3

The final task doesn’t require a lot of scrambling around this time, as you just need to fight the main tower boss. While you can find the Vice Admiral boss when you enter the large middle tower in town, you don’t need to fight this version. Rather, you need to fight the Awakened Vice Admiral. When the event starts, you will get a warning that the fortress has gone still and every marine is looking in one direction.
Soon, the cannons on top of the boss spawn tower will start shooting. The only way to destroy them is to hit the very top roof and subsequent structures under the roof to have the building destroyed. You can use the turret to destroy the building starting from the rooftop. The structure will also glow orange when you aim the turret at it, which indicates that you should shoot that structure first.
Then, all that is left is to defeat the boss. The Awakened Vice Admiral is a Level 130 boss, similar to its normal counterpart, so it shouldn’t take up a lot of your time to defeat it. Finally, talk to the Quest Giver to receive your final star and another 4x Levels.
FAQs
Why doesn’t the flag quest complete for me?
You need to make sure that the flag is hoisted all the way up the pole by stepping inside the red circle continuously until the flag hoisting is done. Only then will Parlus consider the quest completed.
How do I know when the Awakened Vice Admiral spawns in?
Visit Middle Town and speak to the Secrets Master NPC inside the large building with the green dome roof in the middle of the island. He will tell you about any boss appearance and the island just before the boss actually spawns.
Is this island easy for beginners?
Yes, you can complete the island even if you are at a low level, or you can ask your friends to help you with the tasks.
