This is most likely the first achievement you’ll get and it’s a fairly simple one. In order to get out of the POW camp, you'll need to find a way to get past the guards. After speaking with the three POW soldiers in the POW yard, you’ll have a bunch of quests that need to be completed. These quests are:
Find an Item to Write With – You’ll complete this quest when you defeat the giant chicken in the Interrogation Isle and he drops a quill.
Collect an Orque Uniform – Although there are six separate quests including this one, this is sorta like the main quest of the uniform quests. To complete this quest, you need to kill Jungle Beasts, which have the uniform items in their stomachs. Kill the whole group at the base of the jungle and you’ll have acquired the entire uniform set.
Find an Item to Use as Ink – When you’re on your way to the latrine, you’ll be ambushed by several squid. Eventually as you make your way up, a larger squid will attack you. When you kill it, it’ll drop the ink that you’ll need to use.
Find Paper to Write On – As you enter the latrine, you’ll see a giant latrine goo monster at the top. Kill it and it’ll drop the toilet paper you can use as paper.
Learn the Secret Password – After you kill the Goo Monster, two orques will begin talking, you can’t miss it. They’ll say the secret password which you must remember when you are at the bridge.
Forge Orque ID – To complete this quest, go to your inventory and combine the quill and the ink and then combine the quill with the paper.
Once you have all this completed, go to your equipment section and equip all the orque armor in the appropriate slots. Once you’re finished, move towards the Outhouse at the top right and then next to it is the bridge. Make sure when the orque says the beginning line of the password you use the correct statement to finish it.
