Level 10 - Snake Fist
*NOTE: I'll say it now, and I shouldn't have to, but any yellow gas cans you see can be blown up for a free explosive.*
Grenades in front of you, a med kit to your right, and down to the right is an intel on the desk. Behind you and up is the room with the terminal, and at the back of it is an armor in the snack area, but save that for later. When you use the terminal of course enemies will pour in from the two side doors, about eight; so if you want you could have set mines at each one beforehand. Just use a few frags and slo-mo, and the weapon of choice is either the Hammerhead or Assault Rifle. After the last one comes out, pick up the armor and go through either door to fight two more.
Bypass the cleaning chamber and in the next room is a fight with three. Hop out the window and into the next window for an intel. Then hop back out and in the nearby corner you will find a ladder to get another intel. Now just go to the upper right of this whole area and take the ladder down, follow the corridor to another ladder, go up, find the terminal, use it, and pick up the Hammer ammo.
No enemies pour into the now active block 4. Return to the room with the intel and you'll notice the arm is moving about. Take the ladder down and pick up the reflex booster when it's showing. Go directly down the middle to get into the next area. Inside the broken chamber is an intel. Now just follow the path until you see the Armacham crew, then three will attack from the side. Kill them and at the other end of the room are about five more. There is an armor in the room to grab after.
Go up the stairs and kill the two more on the catwalk. Go through the door and there are three more, who offer a good chance to use a flame grenade. Pick up the intel on a shelf. In the next room you will encounter Colonel Vanek. Listen to him and then use the computer, although some of his lines as he waits are amusing. After the decontamination, press the green button on the right and be ready to mash melee, then press the fire button at the end of it.
*NOTE: Remember, slo-mo is the way to go for the creepers.*
Follow the path to the holding cells for test subjects. Crawl under and use slo-mo and the ASP to kill the first two. Move to the stairs and run up and hide in the corner to handle the next few, of which they come from the sides, below, and all over. Hard to help here as they move too erratically, so whenever ready just run to the right, across the walkway, and into the safety of the control room. Use the computer and pick up the intel.
If a little low on health, remember to use a med kit. I say when you exit the room just run right, jump off the broken part of the walkway, kill one creeper, and then crawl under the door to get out. There are supplies in the room nearby inside the storage. Go down the hall and meet with your objective. Swap your Hammerhead for the Pulse rifle, and then that happens.
Go into the hall and use the pulse shot on the three enemies. Then swap to your ASP and kill the next two, one who is above, and get back into the cell area. No, you don't have to kill any unkilled subjects, just the Replicas. Make your way up the steps and then turn around and hide behind the cover at the end of the walkway, and from here I would say use the sniper rifle, especially on the armored soldier because one headshot takes him out. Move up and kill any more you see, and make your way back into control room. And when inside one subject will follow.
Crawl through the hole in the door and kill the three enemies by hopping over the rail, and you can only shoot through the open window. Through the door you will be back near where you started. Kill the first two and hop over. There are a few more as you make your way back, but take cover in the long hallway behind the box on the right, the one that covers your body when you stand. From here you can toss grenades or use the sniper rifle to kill the group and the armored Replica, or use both. When it's clear move up to the newly-opened room and pick up the armor next to your friend.
In the next room you encounter four ninjas. They are slightly camouflaged when still, but when moving you can see their blur and sparking. Slo-mo is the way to eat them, of course, but when out of it you can just fire some ASP rounds into them to chase them away for a time. You can use your pulse ammo on them if you must, but I got through this without using it. After all four are dead, there is armor in the room, then go down and use the elevator. Now a ninja jumps out, but he didn't attack me, so for you I would say either pulse him or go slo-mo, run past him, and use the lift as you wave goodbye to him; your call.
In the next room the two soldiers can't see you through the glass. I chose to snipe the one, and ASP the other, but it's your decision how you want to take them out. Just two more Replicas around the corner and that's it for this school. Pretty wild if you ask me.
