[Playthrough 3 Spoilers] Special Rewards based on Play Records

[Rin]

Since I've been trying to be a completionist on my "first" playthrough, ran into something interesting in the main quest while popping open some chests, as I started getting commented on why I was given a bunch of chests to open.

While playing as 9S (2nd part) in Flooded City, you can get special rewards based on Play Records while inside the Resource Gathering Unit.

Other than the hackable chest at the end of the corridor, I believe there can be a total of 8 additional chests depending on how you have been doing. I only got 6 of them myself, and was wondering what the other 2 are.

Left Side: (from entrance to elevator)
Heal Drops Up +6 (completed lots of Machine side quests)
Hijack Boost +6 (completed lots of hacking mini-games)
EXP Gain Up +6 (completed lots of Android side quests)
Drop Rate Up +6 (collected lots of items)

Right Side: (from entrance to elevator)
Max HP Up +6 (retrieved lots of android corpses)
Faith - weapon (killed lots of enemies)

The one common trait across all these requirements is that these are stats directly shown in "Play Records". As such, I'm suspecting that the last two rewards may relate to dying lots, using lots of items, repairing lots of android corpses or killing lots of infected androids (there is a chance in Route C for android corpses to become hostile infected androids instead of allies when repaired).

Finally, there appears to be a very high (but not guaranteed) chance for the +6 plug-in chips to be perfect (with the little square). 3 out of the 5 plug-in chips I looted from these chests cost only 14.

Lucky you. All I got from there could fill my entire chip space.... twice....

I think I get all chests in my playthrough. And none of those are anywhere near diamond.
