Area 1 (Hounds): The first area you enter will have a lot of buildings with narrow alleyways. There's hounds lurking all throughout the alleyways, so be ready. If you make it to G9, the hound that drops down on you will drop a Silver Moogle Doll, then 3 more Hounds will leap at you at once, so be ready. When you've explored the area, head over towards the F5 area (there will be a Mako Point), proceed through and talk to the soldier to get his cardkey. Return to the Barricade at the beginning area, taking down any hounds that get in your way. Enter through the nearly invisible door. There's a potion in the back corner, but there's no more Hydra case. There's still some ammo at the top. Anyway, head out of the building, there's three more hounds to take care of before we move on to the next portion.
Area 2 (Snipers): Snipers, as you might've guessed, are much more accurate, and they hurt. At least 3-400 HP of damage with each shot. Now if you check your status screen to see how many snipers are left, you may notice that instead of 15 (like Normal), there's now 26. There's 7 in the main plaza area you're in (PLUS a DG Trooper by the Mako Point). All the snipers are located on the roofs around the perimeter. Run back to the alleyway you came from and you can start picking off snipers one by one from right to left. You should be able to hit 5 from that alcove. The other two you'll have to move out a little more until you can see them (they'll be at the 7 o'clock and 5 o'clock area of the perimeter, high up and slightly hidden). When you've killed the 7, head to the alcove on the right and take out the DG Soldier by the Mako Point. Before heading in, you should take the time now to collect items in the other alleyways. Once you head down that particular one, the boy will come (and all the Snipers you haven't killed will disappear too). Now it's time to Protect the Boy. Follow him into the building, head up the stairs and take out the two DG Soldiers waiting for you. Use the shop, grab the items at the top of the stairs (potion and machine gun ammo), then head back down and follow the boy out. There's two sets of guards following him, kill two in the first alleyway you come across, then move to the one the boy is in and kill the next to guards. Approach the boy to activate the second stage mission (Protect the Boy).
Part 2 - Bodyguard
Area 1 (Boy): Note that the boy won't move ahead unless you're by him. So you can feel free to explore the area in between his movement points. Anyway, 1 Beast leaps down past him, be ready to shoot it. Then proceed through the door. Head up the stairs and out to the upper walkways of the main plaza. Two beasts jump up onto the first bridge you cross after climbing the ladder. You can go down the small pathway where the Materia Floater once was (it now contains 1 whole gil for you!). A couple bridges later, there will be two DG Soldiers shooting at the boy from atop some buildings in the alleyway to your right. Take them down, then move on. A couple more bridges later 3 hounds jump up. Take them down quickly, and notice the boy will start sprinting after this (he wises up). The final bridge before the door, a DG Sniper to the left, all the way across the plaza will make his appearance. Duck down and get close to take him down. After that, the boy will unlock the final door. Head in, move straight to the railing of the stairs aiming down, and wait for the DG Sergeant to head up the stairs. As soon as the reticule goes red, fire away until he dies (it might take a couple shots). Grab the cardkey and you're done. After the video, head back in the door behind you and grab the model gun to the right of the door (if you don't have the Ultima Weapon, that is. If you do, you don't have to grab it unless you feel like it). But continue up the stairs and out the door, because 5 more DG snipers have spawned in the Plaza area. They're all on top of a building, well above Vincent's level. You have one almost directly ahead of you, and another a little to the right, one more towards the center, another one far to the right, and the last one is almost directly to the right on the opposite side of the plaza. After they're taken out, head back down and proceed through the barricade.
Area 2 (Alley of Snipers):
Proceed through the barricade. One Sniper will appear along the upper walkway, accompanied by 5 more soldiers on the ground. When they're gone, you'll have a long narrow path with a lot of twists, and a DG Sniper waiting for you on a couple of them. Slowly move around each turn with your rifle aimed high. They're not too hard to spot (they're not that far away), so when you see them, take them out. After about three twists, you'll emerge into a more open area. There's one sniper on an upper walkway (You'll hear "The Keeper!"), take her out. There's two more on the right side of the buildings leading to another alley (They're fairly high up, just look at about 45 degrees from the corner and you should see one of them.) You'll need to take these two out before it's safe to come out into the open. After that, proceed up the stairs to the walkway and head towards the Mako Point. Be careful not to leave yourself visible to the alleyway, as there's an ambush waiting for you there. It may be wise to shoot a few Blizzard Spells towards the alley, take out a few enemies waiting for you so you have less to deal with. Grab the Mako Point and, you may have noticed a Barricade that rises when you approach. Once you drop to the other side of this, there's no going back. Barricades block every path around. In any case, you'll have around 5 DG Soldiers to deal with, all hiding behind white boxes, and there's another sniper on an upper walkway (to the left). When you take all of these guys out, proceed along the left wall. The first gap contains a Limit Breaker (which, if you're health is low, might be a good idea to use). The second gap plays host to 3 DG soldiers, one of which is holding a machine gun, directly in front of you. A further 3 lurk in the back around the corner. AND one more Sniper will come out (further up on the left corner of the building you're hugging), plus another sniper, on the right-hand corner of the building will become visible to you. Step back a little bit to avoid the DG Soldiers (they won't come out of their little niche), and take out the Sniper on the right first. Then aim up and to the right, and slowly walk out from under the walkway to deal with the new sniper on the left hand corner. Then go through and kill the six DG Soldiers, and grab the cardkey (and yet another Silver Moogle Doll ^^). Approach the barricade, but look at the top of the building past it, to the left. Another Sniper. Take him out but head back to the previous area. There's a small gap on the right-
hand side of the building with stairs leading up (and I'm not talking about the one with the barricade, this set of stairs is across from that). Make your way across the walkway to the white box at the far end. It contains another 3000 gil. Hop down and proceed through the barrier. Hug the right-hand wall and proceed through the door. Kill the two DG Soldiers that jump down and take advantage of the shop. When you're set, exit the door and move out to the next part of the chapter.
Part 3 - Warehouse up Ahead
Area 1 (Alley of Soldiers):
The first thing you see is the video showing the staircase with more soldiers perched on it. Blowing up the barrel might take out 1 or 2 of them, but you'll still have to shoot any survivors. Head up the staircase, and you have another narrow pathway with a lot of twists. This one, though, is sniper-free. But two DG Soldiers will rush out after each twist. When you reach some stairs, head to the railing and aim down. Another soldier will rush out, shoot him quickly, then proceed down and grab the Mako Point, and move on. You'll have a couple more twists before you finally reach an open area with what looks like a very rusty bridge along it. There are four Snipers in this area, all of them ahead of you and decently hidden. Blizzard (or Galian Beast's projectiles) can be useful in locating them. There's one on the ground
level at about a 45 degree angle from the left corner. He's your first problem. From there, you'll have a sniper at the far end of you (along the left). Another is hiding on a building high up on the left side, only visible when you're around the middle of the area. And lastly, the final sniper is hiding behind the cage all the way at the end, behind a couple boards. He's a bit tricky to spot because you've only got a small gap to see him, but he's not too hard to see and kill. When that area is clear, you'll have the final area. A small fenced in area by the warehouse with two barrels, 4 DG soldiers, and two DG snipers. The soldiers are easy to spot and kill, the first sniper is on an upper walkway across from the warehouse door. The second one is perched high atop the roof of the warehouse. When that's all clear, use the shop and enter the warehouse (get a Thunder spell ready).
