Yes, the original outfit was a pre-order bonus. It should be available in like two months, but since you don't replay games...
Besides which, the outfit's skirt isn't a skirt but a "skort"/skirt-short thing because Capcom couldn't really model a skirt when she wears pants in the remake.
You probably know this (or don't) but if you perfect dodge then hit L2/LT (ready weapon), the game will go into a "slow-mo" time-dilation mode like the Phantom Pain does when you get near-alerted and allow Jill to counter attack (by pressing R2/RT [fire weapon]).
I'm guessing they couldn't do the same here because the game is so fundamentally different? I'm gonna go watch a run of the original RE3.
They could, but IIRC the soundtrack here is a remix of the original 3's tracks. Something they certainly could've done like 2, though, for sure. Even if they had to put the music in new locations.
The scenario is completely different. While you start at Jill's Apartment (though you don't explore it in the original, you're thrown out by an explosion like on the "second floor" of the apartments here, just onto the streets: Not a fire-escape), the scenario is VASTLY different after that. Because while you still go to the bar and parking garage... the Uptown area is MASSIVELY cut. Definitely replay the original and you'll see what I mean if you check the map (or just walk around). Kendo's Gunshop also changed locations. It's closer to the R.P.D. (since they changed that in 2 as well) instead of being near Jack's Bar.
Oh and the 2 RPD lockers in the Carlos section. Were you just supposed to remember their 3 letter codes from RE2? Only locks I didn't open in my run. Didn't find any hints and didn't remember from last year the codes.
CAP is listed in the briefing room, where Carlos calls Tyrell after the "Big R.P.D. welcome" comment Carlos makes. It's on the white board as you're passing by to unlock the door that leads to the West Wing, Dark Room, and and Evidence Locker/Weapons locker room hallway.
DCM is listed in a file... forgetting where... but it's in the file. If you haven't read all the files, use the PowerPyx video I posted a while back and go through those since reading all the files in a playthrough gives you points for the shop, so you might as well. (As does unlocking all the locks [lock-picks, Jill/Carlos' safes in the RPD and other areas], so just use that video to get a MASSIVE point boost, don't super worry about S-ranking if you aren't going to play the game hardcore)
The R.P.D. in the original was an asset reuse as well. Even with blocked areas. Something they could've done differently was had Jill (who is the one that goes through it originally) meet Marvin [something I was hoping for and doesn't happen in the original] and get information and/or find out about Iron's being involved. But instead they just give the segment to Carlos to give him more to do.
What are the best unlockables to take into new game+ to make the game easier? I've got 7,860 so I can't get anything infinite ammo. Are the attack coins worth it?
Yes, plus the S.T.A.R.S. manual for easier Perfect Dodges. Or the Defense Coins and Regen Coins (though the Regen Coins won't be super useful in boss battles) since if you have both of the regen coins you get back to Fine status pretty fast.
If you still have a save for Carlos (to get the Assault Rifle kills done), or at the Nikolai Fuse section (to get the Jill weapons done, especially the Magnum and Grenade Launcher) you can just farm about 11 kills per run on the fuse section and about 20-50 kills in the Carlos section to get those weapon/enemy kills done. They give you about 10,000-20,000 points to use.
S-ranking and the higher difficulties give you WAY more. I've got nearly all the shop items, bar I think the Attack Coins and Jill's S.T.A.R.S. outfit and the only record I have left besides "So Long RC" is the 8000 enemy kills one, which after abusing the Infinite Rocket Launcher on Nightmare, Inferno (S-ranks for these), and grinding weapon kills and doing Standard (no S-rank yet) for this I'm nearly at the 8000 for that. I think doing Assisted and Standard S-ranks will give me more than enough if I just Rocket Everything.
