Here I have parts 1 & 2 of the Factory. I missed a few items to pick up in Part 1, but went back and found them before capturing Part 2. In Part 2 I focused on showing all the pickups, and verified search completed by showing blue status with the map when exiting areas. I will focus on doing this when I make my walkthrough as well.
These runs went pretty well, I had many flashbangs available, most of which I found. It's really helpful to have 3 for the Soldat Jet and Panzer enemies, both of which are armored and require more ammo than it's worth to take them down. I also managed to solve the Iron Horse Labyrinth puzzle this time, which I missed on my first run. The Iron Horse puzzle is by far the hardest of the 4 labyrinth puzzles for me, but I finally got the feel of it.
At the 12:22 mark in Part 1, when I first saw the loot in the small fenced-in room where the Soldat Elris (1 auger arm) is sleeping last play through, I realized if I could lure the Soldat Zwei (2 auger arms) toward the fence where there's a piece of machinery you can circle around to avoid him, he'd possibly break through the fence. This became apparent to me when I was waiting for it to approach one of those sets of high voltage electrical coils, which shock/stun them if you shoot them when they're near one, because I saw him rip right through a fence to get to me. A video guide I saw recently when I couldn't find the last item in that room, suggested tossing an explosive toward that little fenced in room, which wakes the Soldat Elris sleeping there, and he busts through the fence. That method however wastes an explosive, and any ammo you might have to use to kill the Soldat Elris. Tactics like these and the use of flashbangs and luring the Haulers to their death into the heavy machinery in the Engine Room are tricks I'm using to practice for fresh starts on the harder difficulty modes, where every bit of ammo and cash become critical.
Other than that, some highlights for me were the no miss kill on the Soldat Elris at the 7:26 mark in Part 1, the 3 Hauler kill in Part 2 at the 1:20 mark using just 3 shotgun rounds and 1 pipe bomb, and the 12:27 mark in Part 2 where I landed some pretty good snipe shots through the window on the room full of Haulers, including a 2-for-one shot. These may seem like trivial accomplishments, but they add up resource wise. I DO however keep making the mistake of taking too many shots at the Soldat Elris' when they're stumbling toward me. It's far better to wait until they get to that stationary thrust pose at the end of it, even if it means backing up a bit if you can. Haulers will go down with two well placed headshots each with a substantially upgraded shotgun at close range (on Hardcore anyway), but the way they move, it's often hard to accomplish that. This is why I like to use a pipe bomb to soften them up or finish them off when they're clustered together.
