 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.
 
 Stop Spinning:
 When you are playing and type in god mode or lots of 
 guns e.c.t. sometimes you might start to spin if this 
 occures type in MPINGEMUSTDIE and you will stop spinning 
 and if that doesn't work type in anything with a m. 
 (But the code helps you beat Inge also.
 
 Easter egg: 
 In misfortune in Morrocco, after you finish the first 
 batch of assasins, come out of the room. there you see 
 a man trying to open the door. come out of the room and 
 you will see two windows. get on the first one and it 
 will fall down but nothing will happen. now come to the 
 other side and jump on the small strip which you find on 
 the wall. jump on the window and you will find a secret 
 item. proceed further and open the door. the guy outside 
 will thank you!.(if you have got the belt buckle, you can 
 as well hook yourself to the structure you find above the 
 window and go up)
 
 Tip:1)
 in Alpine Intruge, you can use the snow mobile 
 till you find the gondola station. it will be easy for 
 you to travel till there.
 
 Tip :2)
 if you find it boring to kill people with your guns, 
 you can use the snow mobile and run over them!!!(saves ur 
 ammo also!!).
 
 Tip:3)
 do not use the super atomic laser gun. it is powerfull 
 alright, but it also vapourises the men with their guns 
 without giving u their ammo. so use the ordinary laser 
 which will not vapourise the guys.
 
 Useful hints:
 Even though they may seem redundant, the training 
 missions will get you up to speed on using all your 
 weapons and gadgets. 
 
 Be very careful when trying to complete a stealth mission; 
 even brandishing your weapon can blow your cover. 
 
 Silencers and quiet weapons are very helpful. There's 
 nothing worse than making a racket and having to deal 
 with an onslaught of enemies. 
 
 If your weapon has a scope, always use the zoom feature 
 you will be able to take out targets with far more accuracy. 
 
 
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.

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?" 

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.

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.
