Completion
And now, we blow the whole damned thing up.
Notes
Accepting the quest gives players another ability with the field kit:
Bravo Company Field Kit ACTIVE. Plant Seaforium is now available on your action bar. Toggle Bravo Company Field Kit to DEACTIVATE.
Carefully, CAREFULLY, get to the top of the tower. It will take a distract at the base for the four outside, a chloroform for the one guard inside on the first floor, then sneak up until you're in the "open" level of the tower, were you should wait for the chloroformed guard to awake and defeat him with Jorgensen and then proceed. If you don't do this, the chloroformed guard at the bottom level will warn the other guards on the top-floor and slaughter you. Once this have been done, proceedto the top-floor and walk right(east) and then quickly cast the chloroform pot on the first guard that appears and then the second one and lastly on the guard inside the top-floor room. Hurry and Enter this room and plant the seaforium charge ( If this ability doesn't show up on the "Bravo Company Field Kit then press 4 to plant the bomb) leave the tower quickly by jumping north-east(about the same place the top-floor door/entrence is) and jump away before the guards awake.
You have successfully planted the seaforium at the Blackrock tower.
Same process for the munitions hut, but this time there's only two guards to avoid,
so throw a distraction some distance infront of them and quickly get inside, plant the bomb and then wait for the guards to return to their posts before you try to escape with annother distraction, thrown from the inside of the room as far away from the guards as possible, then run out of the building.
(be carefull not to run into the flags :) )
You have successfully planted the seaforium at the munitions hut.
Head east, then up the hill to Shalewind Canyon to find the Bravo Company and the kidnapped citizens. Don't forget to pick up the flight path at the Shalewind Canyon camp.
