General:
This is really the most difficulty and hardest map of the second episode.
When entered watch out not to fall into the lava boiler. It's a killing machine for all beings.
Upon the big wall there's a SkaarjSniper patroling and surveilling the whole scene.
To get the big wall's door open you have to touch all the gongs in the small huts.
When you're outside the big wall, turn left to the catapult.
It may be used to travel to the small island quickly.
First load it (turning the winder) then climb up and stay left upon the launcher.
Fire at the small bolt in front of your feet.
At the small island you have the task to open the control tower (shoot the door with heavy weapons)
and activate the machine inside of it by turning all wheels faced up
(use the right lever for the back wheel first,
then the left lever for the front wheel
and at least the middle lever until the middle wheel is done).
This will open the boat house in front of the citadel rock.
In the last hut there's the code table.
The code is a four digit number, each digit is representated by a different symbol.
Note this code, it is used to open the main door of the citadel.
Go back to the landing stage and take the boat to the boathouse.
At the boat house take the middle boat to enter the citadel rock. The bars will open automatically.
Inside you'll find the four rooms with the code machines in it.
This is the most difficulty and hardest part of the map.
In the fifth room there are tables to translate the numbers one to three into the symbols.
Other numbers are displayed subsequently at the code wheels.
You now should be able to translate the numbers one to eight into symbols and thus
to translate the small island's code table code into a four digit number (I don't say which one).
This number is to be entered into the code machine:
The first machine gets the 1 at the right wheel and the first digit at the left wheel.
The second machine gets the 2 at the right wheel and the second digit at the left wheel.
And so on. When you entered the number properly the machines ring and the wheels won't be turnable again.
The citadel's main door opens.
Upon the backmost tower there's a red button to call the air ship which takes you to the exit.
To get up the towers you have to go into the citadel wall (there's a hole behind one hut).
Inside the wall turn right and take the lifts up the towers. Be aware of the SkaarjSnipers!
Tips:
On the small island there's health and weapons outside the fence.
The code area is easier in multiplayer when one enters the code while the other block the door.
Before taking the minigun at top of the huts of the citadel get rid off all SkaarjSnipers on the towers.
Else you'll be an easy target.
Secrets:
No secrets - there are goodies everywhere when you open your eyes:
There are jump boots everywhere to jump to the goodie places. The water is full of health and shields.
