After many re-loads, the at-sts are all finally dead, as well as the ion cannons fried. The rescue drop-ship has arrived, and Jan informed me that she'd 'meet me in the canyon'.
Now here comes the tricky bit...
Where on earth -is- the canyon? I can't seem to find Jan anywhere!
Cheers,
Ulaire
Go back to the room with all the inactive AT-STs and you should see a stormtrooper firing at you from the far end from the once locked room. Go in there...
