Okay, Double Agent on the 360. I can't manage to get 100% on the first mission. I don't know what I'm doing wrong, I mean, I've played mission so perfectly that I never even heard the stinger sound when a guard gets suspicious. But for some reason I always get identified as an intruder and my final score is like 95% or something. But like I said, I haven't the foggiest idea who it is that sees me. And I heard that there is an unlockable costume if you manage to achieve the 100% though I only heard that from one source but it has always bugged me that Sam is wearing a cool ninja suit in a few of the Shanghai mission screanshots; any idea if this is true or not--and if not, how does one get the cool ninja suit for the Shanghai mission.

It's a semi-glitch at the part when you climb the fence and into the little area with the searchlight & the 2 guards. If either of those 2 guys so much as even think they hear or see something, you get hit with an ID'd as intruder, and that'll happen all too often, no matter how quiet you move. It sucks, lol.

There's a particular way to get through it that I believe works most if not all of the time, but I'm not exactly sure of the exact method. However Warrior0fLight I'm pretty sure knows it it and will share it with you when he sees this thread

LOL, thnaks insanity. I've answered this qq too often and almost have it memorized...

Yes Jazz, you're getting 97% due to the ID'd hit and as insanity mentioned, it's in the area where you have an electric fence with a gate, spotlight and two patrolling guards. If you make the slightest noise or even partially get touched by the spotlight they will 'see' you, even if you aren't in their line-of-sight.

No Jazz, there aren't any unlockable costumes/outfits for completing said objectives. The only unlockables are the gadgets that you can see in the OPSAT equipment menu.

On to the solution, it's important that you have the 'radar' turned on so that you can see the 'condition' of those two guards. If they turn red at any time you'll have to reload the save and try again, so here goes:

First, here's a couple of videos on youtube that use a similar method to mine.

My Solution:

When you enter this area, head down and to the back, go past the security office and follow the wall until you find a wire to cut. After you cut it to climb over the fence save the game because this is the hardest part in the mission. The guards here are very sensitive to sound and motion, so you MUST move QUIETLY. Anyway - after you save, climb over the fence and wait for the point where the spotlight is scanning away from you then head to the second (I think) row of hardware. Use the 'back to the wall' move against the end of it and wait for the first guard to pass by you. Move quietly behind him to the left towards the ladder and the second guard, keeping to the right side - timing is critical here due to the spotlight. Check your opsat/radar and observe that the yellow dots representing the two guards haven't turned red. If either are red, start over again.

(Normal difficulty) Wait on the right side of the aisle until the second guard is on the way from right to left. When the second guard passes by you, move to the ladder. Once you've reached it, stay on it. Yes that's right. Stay on it and make sure that the yellow dots don't turn red. If you did everything correctly, the guard won't notice your presence on the ladder. Wait there until the second guard goes from left to right, passing by you. That is the moment where you climb the ladder and continue towards the silo ladder.

(Hard difficulty) Instead of waiting on the right side of the aisle, wait on the left until the second guard goes from left to right then slip behind him and very quietly move up the ladder to the silo ladder. NOTE: There are actually two cycles here, one where the second guard moves left to right while the first guard has his back to you, and one where the first is facing you. It's important to only go for the ladder when the first has his back to you!

Check your opsat/radar and if the guards are not red then you're in the clear to climb on top and jump to the zipline.

Thanks man; I did what you said and it got me 100%. And damn those guys are touchy--I'll have to try it on hard next. Thanks again.

Glad I could help. That particular section isn't much more difficult on the harder levels, but you will probably have to retry several times to get the timing right.
