This achievement requires 4 real players, it will not work with you + 3 bots (or any bots).
Also, if you've died in a previous mission (or in the current session), you have to restart the game. Something with the game is bugged where even if you load an entirely new mission, it still thinks you died.
The easiest mission to do this on is R1B1, assuming you do it correctly.
Things to take with you -Weapons -Weapons are a personal preference for what you prefer using, and not everyone will agree with this selection.
My personal recommendations are -
Main -- Van Auken CAB F4 Carbine. This can headshot the smaller enemies relatively easy & fast.
Special Weapon - - Buckland AF6 Combat Shotgun. This is an automatic shotgun, it can kill groups of enemies relatively fast during close range combat.
You should also tell someone to pick the Drekker Inex Drei Scattergun for there Special Weapon, because it can instant kill Giants that are close up.
Super useful for dealing with 1 or 2 of them that are next to you.
Once you get into the mission, clear out the 1st room. There are 3 doors in this room. Explore Zone 38 for any possible locker spawns containing supplies.
- You should now clear Zone 41A & 41B.
- Place the Burst Turret facing Door_668, & Mine the door with 1 Mine.
- Now C-Foam the door.
- Go back & activate the Class II alarm door in Zone 38, all enemies will now spawn from Zone 41B. The c-foamed door will delay the hoard of enemies for a couple seconds so try to focus on finishing the alarm door.
After this alarm door is finished, query the keycard (you can query the keycards location before or after doing the alarm door, it doesn't matter how you do it).
Once you find the key, be sure to explore Zones 43, 41, & 42 to find any supplies or Personal ID's that could be in these areas.Zone 42 is a dark zone, keep that in mind.These areas will have at least 2 Scouts in them, and few sleeping Giants.
The Bio Tracker can scan for moving Scouts, so be sure to use it.
Zone 42B will have a Log in it, so if you're going for logs, get it now.
All 3 of these Zones can be done completely silent, no need to use any ammo at all.
If things do go wrong, just try not to use a ton of ammo.For reference, I found 9/12 Personal ID's in just those 3 Zones alone (I don't mean you'll be able to find 9, it's just a reference number, as the
ID placement is randomized). Remember, the
List_Zone command on the Terminal can save you a lot of time. So can the
Ping [item] command, be sure to use them extensively.
I do not recommend progressing into Zone 44 unless you're already experienced & can handle a Class 3 alarm door. The only benefits this room has is a few extra supplies (you will use more supplies then the room gives you) & maybe 0-3 ID cards so you wouldn't have to go through parts of Zone 39 or 40. Another Class 3 alarm door will exist shortly after this one, leading you into Zone 45, same logic as above.
You should now begin progressing into Zone 39, it is possible for this Zone to have quite a few Giants in it,
I highly recommend going loud & killing all the enemies in Zone 39 so you can explore it freely (and for the other strategies below)
Be sure set the Burst Turret on the bridge in Zone 38, pointing towards the entrance to the Zone 39 door (there will be some sort of light stick above the stairs, aim for that).
This way when you go loud, you can retreat into Zone 38 & have the Turret do some of the work. I wouldn't use any mines at this door just yet, be sure to save them.
Don't forget to use the Bio Tracker!Make sure you explore this whole zone because you could easily get 0 - 3 ID's from this room, along with extra supplies. If you need to back track for more supplies, do so now.
There is a decent chance that if you're lucky, you can get all 12 ID's from just these zones only & complete the mission without ever having to enter Zone 40. If you're unlikely, keep following the guide past this point. If you would like to get the Log in Zone 40, also continue past this point.I would recommend getting any ammo & Tool refill kits you can find & stocking up just incase things go wrong, because the next room will use a lot of your ammo if you go loud in it.
Zone 40A can have a ton of Giants, and sometimes nothing but Giants.- You can probably sneak past the Giants & find the last remaining ID's, but if you would rather go loud, place the turret just outside Door_920, be sure to do this regardless if you go loud or not as a safety measure.
- There will be a concrete barrier, place the turret to the far left of this barrier with a clear view of the entire door. Be sure to place 2 mines on the sides of this door, 1 below, and 1 above.
- When that is done, have 1 person shoot into Zone 40A at some enemies, this will wake up everyone. Run back to Door_920, C-Foam the door, and just wait. Keep C-Foaming the door until all the enemies stop coming, use the Bio Tracker to keep track of all the enemies, and have them break the door down. This will damage or kill most of the enemies except for a few remaining Giants (hopefully).
- Retreat onto the railings in Zone 39A if needed.
After exploring this small section of Zone 40, you should hopefully now have enough Personal ID's to complete the mission.
If you still don't for whatever reason due to being insanely unlucky, have 1 person progress into Zone 40B & get the last Personal ID.It's recommended to stay quiet in this room due to the huge amounts of Giants & Big Shooters it can have (especially if you didn't go loud in Zone 40A).
For precautionary measures, do the things mentioned below -- Place the turret on the bridge right before the Zone 40 security door, the turret will need to be here to shoot enemies while you're retreating back into Zone 39A on top of the railing. The reason for this is turrets can't see through smoke without the Bio Tracker scanning the enemies, and if any enemies are far away, they will never be shot at by the Turret due to not being scanned. This is just a way to get around that issue.
- Place 2 mines on Door_252.
- If a player makes a mistake and awakens all the enemies, C-Foam the door as well. This will help damage any enemies that get stuck behind the door with the 2 Mines.
- Be sure to place Mines (near the door) in various areas on the ground as well, preferably all of them if you have any left. This will help deal with a few enemies.
- When this is all done, retreat to the long railing in Zone 39A & shoot any enemies that get close. Hopefully you'll have enough ammo to kill everything.
- Don't forget about the Terminal in Zone 40!
After you've grabbed all the ID's, simply head to the Extraction point & complete the mission.
