So I'm done with Chapter 5-2. But it was hard and I died (or failed the mission) three times. I ran away from the two Iron Maidens down in the dump, and I reckon I escaped Leon and Ashley being skewered there by a split second as I escaped. The wrecking ball room saw Ashley get killed twice before I figured that getting her to wait (and therefore not jump down into the room straight away) when you first arrive buys a few vital seconds so that you can use an incendiary and then a frag grenade to clear out a large number of the original Ganado mob. So did that, then called Ashley down, then just ran aroun, and used headshot and melee combos (aiming to knock them into the lava pool)- that worked fairly well. And of course a few flash grenades to knock out the many Plagas that sprout here, but keeping a couple in reserve for the upcoming truck ride. So eventually on the third try I got past that hellish room.
Next were the two Regenerators in the narrow corridor and meeting room area. Normally, these two Regenerators are the least threatening two encountered in the game because they have less Plagas than the others, but on this particular walkthrough, without a rifle and a infrared scope they are among the most challenging, simply because it is very hard to run from them because of the narrow spaces, the fact that you'll likely have two after you at once, and the fact that you get delayed while waiting for the door to open at the end of the area- so if you haven't put enough space between them and you before that, they'll likely catch up and murder Ashley.
So I decided to take the slow approach...I knifed the first one to death. This I did by luring him from behind the shutter with a very quick "Wait/follow" command, then made him come after me into the side room with the dog cages. There, I shot his head off with the Butterfly, then took out a leg with another shot, then knifed...and knifed...and knifed. It took him thirteen minutes to die!*** Once that was done, dealing with the one further down the corridor is pretty easy, I pressed the switch in the meeting room to open the last shutter, let the Regenerator come after me (I'd left Ashley parked next to the dog cages), then lured it back into the dog cages room, gave it one blast in the head to slow it down, then called Ashley to follow me and ran. And made it out easily.
The truck ride was the final bit, and it was hard as expected! I made it to the very last bit- literally the bit where you have to shoot the oncoming truck- but then got attacked by a Ganado when I thought I had killed them all- and if you get attacked or otherwise interrupted while trying to shoot that truck, death is unavoidable. Wasn't too happy at that...but on the second time I was a little more careful. And made it through
So died three times in the chapter unfortunately- my second worst chapter of the game after 3-1 in terms of deaths/ mission failed. So I've 'died' fifteen times in total now- and by my count five or six of those have actually been Ashley dying, which of course is still a failure on my part, but is REALLY annoying nonetheless.
So on to 5-3 I go, which thankfully won't need much ammo to be used. Not compared to the ammo drain that 5-1 and 5-2 were anyway. I'm going to attempt knifing U3 as well as Krauser- call me crazy- but I think it can be done.
Chapter 5-2 stats
Accuracy: 85%
Kills: 81
Died: 3 times
*** If attempting to knife the first Regenerator to death like I did, it is VITAL that you lure it well out of earshot (the dog cage room is a good option) from the second Regenerator further down the corridor before you shoot its head and legs out- otherwise, the second beast may just hear the commotion and you'll soon have two after you at once- and in those narrow spaces, it could get ugly very quickly.
