Citadel

citadel is the FINAL area in siege wars and gets really hard and gets hardcore. it can also make you feel uncomfortable, unsafe, its over, overpowered, un welcomed, etc. it introduces two new mages the violet mage and the ghost mage who is king of all mages. citadel also added the final weapon the stomper which is the most overpowered weapon in siege wars besides the bombard it has moving bricks, working vehicles. and things you would never see ever in any game like angry birds making the game really unique. it also releases the most powerful brick, metal and shows some pretty cool designs. this also backtracks on the whole game on each level it has the mages that you have fought throughout the entire game. and holds the final level. the currently hardest level is not the final level but the one before the last level. which is really good because it gives you a challenge

the final level
unfortunately, the final level does not set in the castle like i thought would happen a long time ago. instead its outside with a hanger design. with the ghost mage in a safe area and the hanger contains every mage you have faced in the entire game including the new violet mage. the survivors are normally the ones on the front. and on this hanger it introduces every mage from when they were introduced from the sand mage to the yellow mage to the green mage etc. and finally at the end of the game it reveals a sad cutscene indicating: goodbye! hope you enjoyed this game! with the new mage the water mage. which is a relative of the frost mage!

alpha version
in the alpha version of siege wars before citadel was realeased it was named mysterious castle.
