Hint: Alpine Intrigue: Mystery weapon:
In scene 4 immediately after you blow up the barrels, go a few turns and you will take a left curve at one point. There are two enemies there that you kill, then two more men that will come running around the corner. Kill them and directly in front and above you is a gun with a wooden stock and a magazine that protrudes out the side. However, you cannot reach it.

Hint: Berlin By Night: Hidden message:
Make your way into the sewer. At the foot of the ladder, there will be an impassable grate to your right. If you look through it, you will see a sign that says "Mandatory FPS Sewer".

Hint: Misfortune In Morroco: Comment:
In scene 1, shoot the ambassador to hear a funny remark of someone saying "Damn it, can't you shoot straight?"

Hint: Misfortune In Morocco: Cate stands:
Get to the place where you are supposed to meet Bruno. Make sure he is straight ahead. Keep going forward until you see markings on the floor. Shoot Bruno, then quickly walk forward. If done fast enough, you will see Cate just standing there. If you skip it, you will see Bruno's dead body on the floor.

Hint: Misfortune In Morocco: Corpse desecration:
When Bruno dies, shoot his legs. A message will appear, stating that you are desecrating Bruno's corpse.

Hint: Misfortune In Morocco: Simian casualties:
At the start of the level you will see a man with a monkey talking to a guard. If you kill the monkey, a message will appear stating that there have been unacceptable simian casualties.

Hint: Misfortune In Morocco: Secret room:
Finish the first part, protecting the ambassador. Once done, you will hear, "Now go to room 12 and wait for him to arrive". Instead of doing that, go to the man who locks himself out. He is the first civilian that you see. Go to the courtyard. Once you get to the entrance to the courtyard, make a quick left. You will see a ledge. Jump onto it. Note :It breaks very fast -- quickly jump to the other ledge where the windows are open. Be careful or you will fall. Once inside, check it out. Note: Jump into the window with the clothes line on it.

Hint: Rendezvous In Hamburg: Coin trick:
Take out a coin and throw it at someone's body. It will slide down their legs and go onto the floor.

Hint: Unexpected Turbulence: Hidden sequence:
Wait until you have to grab the chute. Before the scene fades out, shoot the man with the parachute. In the intermission sequence, you should see the man fall through the barn, and then see Cate fall through it. You will lose the level, but it is funny to watch.

Hint: Sleeping woman:
When you first start out in the training building, walk around until you find a window with a blind all the way down, one crooked, and one three quarters of the way up. A woman will be sitting there with several "Z"s floating around her head. Give the window a good whack and she will jerk a bit and get back to her laptop.

Hint: Proximity explosives:
Proximity explosives will stick to anything grayish.
