Okay ... After playing through this son of a ***** at least a hundred times I finally figured out how to complete it relatively easy. First, rather than the default 11 minutes you are only provided 9 minutes to upload the abort codes. 2 minutes may not seem all that great but when all enemies are ****ing sharpshooters every second counts.

Most paramount is the checkpoints. I immediately noticed that on certain sections of the map I was not receiving my checkpoints. It wasn't until playing it through from the beginning that the reason dawned on me. You have to reach these certain points within the map in a specific amount of time before a checkpoint will be granted. If you are not granted with a life saver you were too slow and CoD4 deems your mission a failure under the impression that you do not have enough remaining time. Why is this? I have no clue but after another go around I have all the check point markers.

The first checkpoint, after taking out all enemies in the hallways and proceeding to the stairs is your first. You must reach this point on the map no later that 7 minutes and 30 seconds (7:30).

If you have not already procured a Sniper Rifle the standard Assault Rifle you have will suffice. The object here is to move Briggs and and the Captain forward as they are Invincible and will not die. They should smoke most of the oncoming enemies for you while you sneak around taking your first right and working your way down towards the end at a steady pace. Once this hallway has been cleared move out and head towards the next doorway. You have to reach this point in the map no later than five - five and one half minute (5:30). Here you should be granted another checkpoint.

Blast the 2-3 enemies who are not hunkered down behind the crates. Once they have been disposed move down and hold position near the two doors to the left and the right. Briggs and the Captain will follow you down to provide suppressing fire. Chuck a flash bang in the right doorway and immediately follow through and take the enemy out at the end of the catwalk. Move forward and another 2-3 more enemies should emerge from the doorway on the left. After they have been handled toss another flash bang into the room then pick off the remaining enemies at the end of the hallway. move forward and again, 2-3 more enemies will emerge from another door on the left. Take them out, flash bang, and finish off the dudes at the end of the hallway. Move forward, take a right, and proceed into the blast chamber like area. You have to reach this point in the map no later three - two minutes (2:00). You will be granted another check point.

The door will slowly creep open. Pick off the guy who jogs down the center followed by another in the same area. strafe left and take out the dude in the room to your right. Flash bang and move in. To the left is another hallway. Smoke all the enemies down at that end then move towards where you place the C4. You must reach this point no later than two - one minute and thirty seconds (1:30). A checkpoint will be granted. Let you people move in and kill the majority of the enemies inside. Afterwards, go inside to do the custodial work by mopping up the remaining one or two. Then the move towards the keyboard and upload the abort codes. Another check point will be granted and the timer will stop. Finish the mission and call it a day. Took me roughly 6 hours to figure out then complete. Hope it helps because I sure as **** couldn't find any.
