I am stucked at one level for this game Fear 2, so therefore can anyone please give me a link or so for this games walkthrough or any cheat codes so that I can easily finish up the game asap. I am stucked on the part where you are following a guy, and he goes up on a platform. I hit the button to lower the platform. Get on it, kill some invisible guys, and take the platform to the top, then I can't figure out where to go from there. Please help me.

You are playing this on a console Playstation or Xbox 360 or on a pc cause then the walkthrough, cheats, etc, may differ. However, you can check this walkthrough made for xbox 360 version.

Chapter 01 - Sanctuary
You start off in a destroyed street. After the little girl disappears, stumble forward, following the little girl as she appears. When you reach a glowing hole, drop down into it to trigger the scene where you meet your team.
After the ride with your squad ends, exit the vehicle and check your PDA to see your current objectives, which are:

• Place Genevieve Aristide in protective custody.
• Rendezvous with your team in the building lobby.

Head towards the main entrance of the building, where you’ll see the main entrance is blocked. While facing the main entrance, turn to your right and look at the coffee shop that is nearby. Enter though the doorway to the coffee shop.
Go through the coffee shop and into the stairwell. You can try the door up the stairs, but it will be locked – instead go through the door at the base of the stairs, hopping over the handrail to gain access to it.
Proceed through the door and meet up with your team. They’ll have a discussion and determine that you need to get up the building. Meet up with your team at the elevator. Once the quick action scene happens, get into the elevator with Stokes.
Once you reach the top of the shaft, eliminate the three enemies in the room and then proceed through the door where you’ll fight more enemies. Make sure to look out for the ones on the balcony.
INTEL 1 of 4: After killing all the enemies, meet up with Stokes at the keycard accessible door. She’ll break through. Just inside the room is a piece of Intel.
After you grab the intel proceed through the glass hallway. You’ll have to sprint in order to survive the chopper that is shooting at you. Just get through the hallway, grab the weapons and armor at the end of the hall and then keep going through the doors that you can open until you reach a room with a balcony. Go through the doorway that’s to the right of where you entered.
Go through the doorway, following the path before you, and be ready for a fight. Enemies will attack you just after you pick up the grenades in the room. Kill them, go up and around on the balcony to reach the level they were assaulting you from, and then proceed through the hallway – marked by an Exit sign – to reach the next engagement.
You’ll fight between 5-8 enemies. Using the various cover you have access to, flush them out with grenades and then kill them. Once they are dead, proceed into the building in front of you and go through some metal gates and through the Exit signed door.
Just through the door you’ll enter a kitchen; four enemies will attack you. Once they’re dead, continue through the kitchen until you come to a shattered window. Go out the window, jump to the window washer’s elevator – which will almost fall when you do so – and then go through the opening heating duct on the other side.
You’ll exit the duct into the room with a large fountain. Jump into the fountain to trigger a cut-scene. After it ends, go through the only open door in the room and follow the path before you until you reach a wooden door next to some showers. Go through this door, where you’ll fight around eight enemies – dispatch them with well placed grenades.
INTEL 2 of 4: There is also a piece of intel in this room, sitting on the breakfast bar, close the grand piano.
Go through the room and up the stairs to the next floor. When you reach the top of the stairs an enemy will kick open the door and try to surprise you, so have your weapon aimed at the door as you approach.
INTEL 3 of 4: Just as you go through the doorway that the enemy kicked open, a piece of intel will be lying on the floor, close to a bust and a knocked over shelf.
Go down the hallway and into the bedroom that it ends in. The room will seemingly be a dead end, with nothing to explore but a bathroom. Just make sure to watch for the little girl who appears, opening a music box before she dissolves. Once she is gone, walk over to the music box and hit X, triggering a cut-scene and revealing a hidden passageway.
INTEL 4 of 4: As soon as you enter into the secret passageway, intel will be sitting on top of a filing cabinet, just below a large map on the wall.
Proceed through the passageway until you meet up with Aristide, your objective. Something strange will happen, and so after Aristide dissolves, you must backtrack the way you came, following the little girl apparition as she appears. You’ll follow the little girl until you get back to the room with the grand piano, at which point a cut-scene occurs where you bear witness to a nuclear explosion. This ends the first chapter.

Reflex Injector locations
Search the following locations to find the corresponding Reflex Injector:

Mission 2 - "Awakening": After the elevator cutscene, you will find a double door that requires a key card. Go past it, and enter a small room to find the keycard on a dead man. Return to the first set of doors to get into the room with the Reflex Injector, which can be found on a shelf.

Mission 3 - "Discovery": After going through a vent, there will be a worker executed by a flamethrower soldier. Look on the floor of the bathroom in this room to find the Reflex Injector.

Mission 4 - "Withdrawal": Immediately after Intel 26, go down the stairs to the left. The Reflex Injector is on a counter. Once you reach the elevator that goes up, you will see it.

Mission 5 - "Replica": After looking at an Abomination with the monitors, go through the double doors directly across from it. Turn off the valve to a flaming pipe that blocks the room with the Reflex Injector sitting on a shelf before coming into the Abomination monitor room.

Mission 6 - "Ruin": During the battle around the downed plane, once upstairs, go all the way to the back of this same building. You will find a box with both Intel and a Reflex Injector on it.

Mission 7 - "Top": The Intel and Reflex Injector are both on the same table when you arrive at the closed doors that you have to open. When you exit the power armor, it is to the left, up some stairs, and in the room on the table.

Mission 8 - "Elementary": It is hidden under a projector in a room in the hallway with yellow lockers and where ghosts start to appear. It is the room on the right after the trophy case.

Mission 9 - "Nurse's Office": After seeing two soldiers get incinerated, look in the bathroom on the right in the hallway, where there are some corpses over a barricade.

Mission 10 - "Snake Fist": After returning power and stopping the lockdown, go back to where Intel 54 was found. Go down the ladder where the mechanical arm is moving. It will uncover the Reflex Injector for you to pick up.

Mission 11 - "Keegan": When you walk upstairs, go to your right and back down the stairs. You will find the Reflex Injector and armor seen earlier.

Mission 12 - "Epicenter": Just before you enter the theatre, enter the room where the laser man breaks down the doors. The Reflex Injector is to the right on a counter.

Mission 13 - "Approach": Look in a little nook away from the major part of the same room as Intel 70. You can reach it by going up the platform, going straight off it, turning to the right, and dropping down a ladder and climbing up another one. It overlooks where you initially came in the room.

Mission 14 - "Climax": Immediately as you exit the tunnel after seeing "the tree", the Reflex Injector is directly in front of you.

As their name suggests hints are not exactly F.E.A.R. 2: Project Origin cheats, and are usually just simple (but very useful) tips on how you can unlock secret level, features, find hidden areas and such. Hopefully these will make playing F.E.A.R. 2: Project Origin even more entertaining.
