GTFO: R6C3 - Pressure Point (Overload)

Moved up from doing a Secondary to an Overload for today, just in time before Rundown 6 gets extended too.  Our load outs were as follows (full hammer squad for jousting):

Archer: Carbine/Scatter Gun/Burst Sentry/Hammer
Me: Pistol/Shotgun/Mines/Hammer
DL: DMR/Sniper/Mines/Hammer
Jim: DMR/Shotgun/Burst Sentry/Hammer

As this is also a "bonus" objective, you need to win the main mission as per before. The general overall tips are GO FAST and lock melters are amazing.You don't want to still be dealing with the lower levels as the infectious fog rises. The change to the path is a minor one: right after plugging in the bulkhead key select OVERLOAD instead of main (that's around the 5th paragraph in my previous guide).

The white path is what I did (key grabber) for the overload section.

Then make haste back to the North while following the HUD display. The overload bulkhead is down some stairs and doesn't need a scan or anything, first one to get there just pull the door open. Once inside rush up the stairs directly to the big door across, get inside mine, cfoam and turret that thing. Right beside the door is a terminal where you must type a command SCP_ZONE_PURGE and sit in a really long team scan.

Survive the waves that come and once that's done go back out the door and open the security door across from you, the one beside the stairs you came up. One person needs to run in there, turn right, go through two doors and find the next bulkhead key BUT BEWARE! Inside that zone is a sleeping father/tank. If you are lucky, you can stealth past. If he's at the door like he was for us, setup reverse waterfall of mines (floor to ceiling at the door) and make him run through it then kill it quick, remembering you need to destroy the cancers on its back and it is invulnerable from the front.

While the key grabber (me) does his thing the other three must continue to hold the waves which likely include giants. On any downtime they should loot as much as they can, prioritizing ammo over health. When the key grabber returns, everyone must make a dash back to the bulkhead controls, plug the key in and activate the MAIN mission, which you will then need to finish off.

The only wrinkle at this point is a second father appeared during the checkpoint scan for us. Archer made a good strategy to kill him as the room right beyond the checkpoint door has a balcony - while he and DL held off the spawn and sniped the father Jim and I scavenged more ammo deeper in to give to them (we were out at that point). After killing the father as a team we continued the escape part of the mission, with scarily low amounts of ammo! Fight well, hammer when you can, and remember the father and giant strikers can actually hit through the balcony grating. Took us a few goes but we finally managed to GTFO!
