I'm not gonna write the prelude now cuz i'll do it later, but basically, Morsh has you get him a sandwich (His fourteenth in twenty minutes)but the platter of sandwiches next to you is empty. This means you have to go down to the Mess Hall(You are on the top floor, it is on the bottom) and with the scent of thirteen sandwiches on you, hungry squirrels (don't ask me how they got there!) will attack you. There is an elevator in the cafeteria, which takes you right back up to the room you were in, and the sandwich turns out to be a bomb. You track the bomb to an enemy fortress, and that's where the game begins. Mission Objectives:

A: Find keycard to exit base
B: Journey behind enemy lines
C: Enter through back, where weapons are shipped
D:Make your way down to the basement, where you find an odd ray. Leave it be for now
E: Defeat the yeti in the basement
F: Find 12 iceplanes
G: Defeat the polar bear on the second floor
H: Find nine black keycards
I: Destroy the heat rays
J: Escape the collapsing hangar
K: Find Lieutenant Bob and Defeat him
L: Attack the inventors rebuilding the heat rays and aims the rays at the enemy ice tower behind you.

No time limit, this would probably be a long mission.
