door wont open in hanger

[gome451]

I've destroyed the atst's, but the door on the top floor won't open. Any sugestions? It's the level outside of the Mine.

You descend back down the platform lift to the start of that level where you met the first of the AT-STs.

 

Then work your along this original valley to meet a third AT-ST. I found it easier just to leg it along the valley floor, straight past the AT-ST and into the hanger it came from.

 

Than hang a right through a door which will take you up to the ramparts.

 

Then run all the way along the ramparts ignoring the Ion Cannons for the time being. You need to explore the rooms at the far end with the dormant AT-STs.

 

The lowest room has 4 officers in it and the switch to drop the forcefield protecting the guns. You can then fight your way back to destroys the Ion cannons using any of the ack-ack guns.

 

This is a tough level.
