Dragon's Hideout

Walkthrough
In the icy village, use Aiden to find the house on the far left side where the crew can set up and rest. Have Aiden help build the fire, then talk to Ryan and go outside to relieve yourself. Go to the end of the village and enter the hanger with Aiden. Take control of one of the soliders and kill the other one near the submarine. The third one will come over after hearing gunshots, so go ahead and kill him too. Use the soldier to open the hanger, and get in the submarine. Steer the submarine to the base without hitting the walls, which should be relatively easy. During the interrogation, you can decide to talk or not to talk, both of which will net you trophies for your decision. If you don't talk, Ryan loses an eye, which is reason enough for me to have chosen not to talk. Eat that! Get out of the sub, and walk towards the soldiers to see how you got captured in the beginning. As Aiden, make your way to the end of the orange hall and go into the armory, killing the guard here. Enter the control room, and try to interfere with the controls. This doesn't work, so take control of the guard and go grab a weapon from the armory, and return to the control room for some sweet revenge. Disable the forcefield, thenf ollow the purple line to get to Jodie. Heal her and Ryan, and grab the explosives from the interrogation room. Before you enter though, kill the guard in the interrogation room with Aiden or you're gonna have a bad time.

Make your way through the main red hall until you get to the pool which will let you dive into the ocean. Suit up, and dive down into the water to plant the explosives. Once you plant them, head back up the path and do the interactive scene, which lasts until you get back to the pool. Afterwards, the scene changes to a new interactive combat, and will continue as you run through the base and the collapsing halls. Get in the sub, watch the scenes, then swim to the surface. Talk to Ryan however you want, and lol about his eye.
