in het engels, ik hoop dat je er wat aan hebt...
Remember the layout of the shop before? Good now head back into the shop. Head through the first set of doors to the right, and then through the next set. Head to the right and through the gun scanner, then through the next doorway. Head to the left first and to till you can rescue a shop employee. Then head back to the first intersection and head right instead of left. Head down the hallway to the place where the bathrooms are on the left and the hole in the ceiling is on the right. If you need health go in the women's bathroom, otherwise use the file cabinet and jump up through the hole in the roof. Now crouch down to go through the vents. You will have to crawl through the latter part of the vents once you reach a little ways into it. When you reach the overhead walkway (still crawling) go left at the first turn, then right and proceed forwards until you are across the room. At the end of the vent, snipe the guards down below before dropping down. Facing away from the door with the scanner, head to the right. If you need it there is a large health inside the first door to the left, otherwise keep going down the hallway and use the elevator to exit the level.
Texas: The Shop Level Two
Go to the right a little bit and watch the nice explosion. Then head back the other way towards the weapons research and dev section. Go through the door with a scanner and follow the hallway to the right. Head forwards to the research section. I recommend on stalking up on weapons. Go to the left and head to the armory/firing range. The door on the left is the firing range and the door on the right is the armory. Clear out the armory and pick up a ton of ammo/health/armor. Then head back down the hallway and onto section 2-C. If you want head through the hand scanner door and kill some more bad guys, otherwise just keep going down the hallway and use the elevator to exit the level.
Texas: The Shop Laboratory
Exit the elevator and head to the right. Go through the door with the hand panel and head to the left through the double wooden doors and then through the lab and out the door on the other side. Go left, away from the water, and through another hand scanner doorway. Follow this hallway and turn left at the first intersection. Head down this new hallway and into the first door on the left. Follow the lab until you see another hand scanner type door, and go through the single door at the end of the lab to get to it. Head left through the lab and at the end look to the left to see who the traitor is! After a short cut-scene, turn around and head out the hand scanner door behind you. Head to the left and then take a left at the next intersection. The elevator at the end now works, so exit the level.
Texas: The Shop Roof
Now it's time to have the final confrontation, the big show down, the grand… why the hell does HE get a big machine of death and your stuck on foot!!! Oh well I know by now you all have favorite weps and strategies, so I'm just going to give a few tips. First thing you should do on this level is run out the doorway, go right, jump over the railing, run to the right and to you right will be a doorway. You should pick this now before the helicopter gets a chance to come around to where you are. This place is good for hiding, and it has 2 armors, health and ammo, just in case. Now as for taking out the traitor, first steps are just like the hospital roof. Shoot off the panels covering the wiring on both engines, and then shoot out both engines. There is a difference in this one though, because once you shoot out one of the engines he will not only use machine guns, but rocket launchers! Once both engines are taken out you will see the cockpit pop off. Now 1 really good shot to the head of the pilot will take this bird down for good. With the sniper rifle it only takes 1 clip of 5 shots to take this guy down. Also using the pillars or the venting on the upper level for cover from the machine gun fire is the best. I've noticed that sometimes you won't see the cockpit fly off until you've done more damage to the helicopter. You can also shoot off the mini missile racks, the side missiles and the landing gear of the helicopter. Good luck and enjoy the ending once you have beaten the game.
