Exploring the Order's base | 11: The Order DMC: Devil May Cry Guide
Last update: 11 May 2016
Turn right on crossroads. Stay close to the right wall while moving through badly lit corridors. Nearby you can find a new Lost Soul. Be careful, because on your way back to the starting point you'll be attacked by a single Ravager.
Now you choose a corridor (screen above) on right from where you've begun exploring the main base. Also here you'll run into a Lost Soul.
Continue walking, finding among others locked door. Then look for a room with a key (screen above). Turn right and go through the wall using Eryx gauntlets. Now you can pick up a Copper Key.
Go back to the starting point and be ready to eliminate another Ravager. Now choose the left corridor (screen above).
Stop when you reach a destructible wall. Use an Arbiter to destroy it, what gives you an access to another Lost Soul.
Continue walking. When you run into another blockade, use Eryx to go through the right wall.
BONUS MISSION: If you want to reach a new secret, you have to act quickly. Move on, looking for a left passage (1st screen). Use it before the barrier closes. Search nearby corridors and you'll find a Secret Door. If you have a Copper Key you can open it, beginning the bonus mission The Power Within. Here you have to eliminate all monsters having the Devil Trigger activated, which's duration is extended every time you kill anyone. Don't experiment, just use Angel Lift and make quick blows with Rebellion.
Look around for another Lost Soul. A bit further you find also Divinity Statue. Use it if you want and resume walking.
After reaching stairs, turn left and pick up a Small Devil Trigger Star which charges Devil Trigger bar. Return to stairs and enter an area where the final battle takes place (screen above).
