Act 4: The Long Road Home - 4. Storm the Castle
Go on and take cover be the railing. These guys never rushed me from this position, so I think you can just hang around and pick them off one by one. Be mindful of the Theron Guards and their Torquebows. Ammo behind the center stairway, near the wall. That should be all you need, but there are two more in this area, but don't forget the two Torquebows. Now go to the left pathway. Be ready for three guys to attack; I used the Torquebow and aimed for the dirt to either kill or flush them out. Keep one arrow in the bow and move up to the statue area, but don't leave the archway. Build tension in the bow and then get a read on the Troika on the bridge to kill the gunner. Then pick off the other two guys behind the sandbags. Ignore the ammo and follow the path, and then take cover behind the doorway and take out the two Grenadiers; two more after them I believe. Then go down the path to the right of the locked gate and cut that gunner in half.
*There is a Torquebow in a path behind the statue.
Come back and collect ammo, there is some by the statue, and the Frags at the end of the bridge. I don't know when he pops out, but a Theron will attack from the sandbag area. Continue up and past the gate.
The scene you get when you approach the stairs tells you what you face. Just watch all your sides. Then a Boomer will show up, so use the Torquebow. Then make your way up the stairs and be ready for some Theron Guards and others, all I can say is take cover, because their movement is so random.
Ammo all over the place, and then go up for a scene; no fighting up here. Get a Frag in hand and go into the house, run up, take a left at the stairs, go into the second room, and toss a Frag as the hole opens. Come back and go up the stairs to a firefight. The Drones are on one side or the other, so take cover on one of the supports with the Torquebow in hand. Shoot the furniture if someone hides behind it to take them out. Watch for the Grenadier to rush. Ammo up here if you need it.
