i am trying to beat the third level (special delivery) can you beat that without getting the enimies to set off the alarm??? If so how? if not how???;

on the main menu press.SQUARE X2/CIRCLE X2/L1 X2/R1 X2/L2 X2/R2 X2.start the game and confirm correct entry by viewing the in-game options[while playing]and see if you have some new options to adjust the difficulty of the game.ie set enemy level value to YES then theyll become incredibly stupied,then you can slaughter them easy!

the goat herder will grass you up,so sneak past him or kill him,as he alerts the guards and makes the mission harder.
use foley to snipe enemies in bunkers.sneak into the base at back entrance,head east follow the narrow walkway along cliff edge far north,then west to back of base,theres guards so be alerted,snipe tower lookouts avoid enemy fire.enter northeast building retrieve scud location files.they on 2nd floor.go to first mig west of 2 buildings.open door destroy fuel tank inside to blow up entire building.keep your men away from entrance of hangar or they will die.the power for the SAM is in building to the west send jones in with c4.you can detonate now or wait and set more c4 in soth of base then call in air-strikes.the other MIG is in a hangar on the south set of buildings.to extract just head to main gates and open them then run straight across the field towards the chopper..

dude you forgot a big part like how to get past the guards with the gate with them not putting on the alert???
