The criteria for the unlockables in the game (possible spoiler)

[xfactor]

Do you remember how you unlocked the costumes?

I'm digging the Miami Vice vibe.

EDIT:

As for getting S ranks, upgrading the handgun all the way is a bad idea. It kills zombies in one hit, pretty much regardless of where you shoot them, but especially if you shoot them in the head. So even if you're killing them by shooting them in the head, it doesn't count as a headshot, because they're heads don't explode.

They're rank base. S ranks all chapters per scenario unlock a couple of costumes. Operation Javier secret mission doesn't unlock anything

How do i unlock Ada's bio???

Did anybody see my post??

[Archelon]

I'd happily tell you if I had any idea where I actually found it.

I have it, but I don't remember specifically where I found the icon. If you just screw around in the RE2 chapters on hard (my guess would be ch. 4) destroying things, you'll probably find it eventually.

[RE-Hiro]

Thanks!!!!!!!!!!!!!

Anyone completed Very Hard yet? I'm curious to see if it gets you anything beyond a meaningless title.

Also, as a side note, I believe Manuela's lullaby, the final VOICE file in O:J, is found in those crates at the end of Chapter 6 (where you fight the Anubi before the boss).

I think I've unlocked everything there's to unlock (for the archives) in normal mode, so I am going through hard mode now. I'll be adding the locations in the OP for the Umbrella icons which I've found in hard mode as well as what they unlocked. It'll be a long process though...

I'm about halfway through Memory of a Lost City, and I haven't unlocked anything so far. I imagine all I'll get is probably just a Title. I'm hoping I get something more, though.

It hasn't been that difficult so far, either. The maxed out handgun alone pretty much takes care of everything. It's still next to impossible to score headshots though. I'm not sure I'll be able to S rank any of the early chapters now.

What is this "OP" you refer to? Could you provide a link?

I was finally able to get S ranks on all the chapters in the game (including the extra Krauser ones) on hard mode - no infinite ammo for me! This leads me to believe that every chapter has to either be beaten on very hard, or be beaten with S ranks on very hard to get infinite ammo! As if head shots weren't impossible enough for me to pull off in hard mode...

On a side note, I was finally able to unlock every archive item in the game (excluding the titles) bar two - a couple of text files hidden somewhere in Operation Javier ch. 6, presumably on hard mode. I did find, however, the following icons:

- In one of the lamps on the central pillars in Javier's courtyard.
- In another one of the lamps on the central pillars in Javier's courtyard.
- In the crates in the warehouse (DarkMemories confirmed this to be Manuela's Lullaby for the Voice section).

I took the right path in the human remains tunnel, so I'll have to go back tonight to see if there's another icon on the left path. Also, I unlocked Wesker's profile in this chapter, but I'm not sure if I did so by finding an icon or by beating the chapter on hard with an S rank.

So you found Javier's Private Messages?

[Det. Beauregard]

So you found Javier's Private Messages?

I guess I did, although I have no idea where I found it. I really should have kept a log of what I unlocked after each chapter.

My recommendation to you is to get the linear launcher (beat all chapters on hard) and fully upgrade it - especially its charge time. You can then just blast the crap out of any destructible object you see, with only a few seconds between each shot. I wish I could help more, but I just don't remember where I found the file.

[Archelon]

That's actually what I've been doing, ha ha. I've destroyed pretty much every destructible object in Operation: Javier, and I still haven't found it. I went through that courtyard a ton of times too just to make sure I got all the lamps.

I'm playing through on Very Hard right now, so hopefully, with any luck it'll pop up somewhere in there.

What is this "OP" you refer to? Could you provide a link?

OP as in opening post of this thread. Yes there is an archives item hidden in one of the crates beyond the gate on the left path. there's also a herb and when you spin around, you'll face with 2 plague crawlers.

I unlocked Wesker's archives in Normal mode, thus I can confirm that difficulty isn't a criteria here. I strongly believe only parts of the texts and all of the voices are hard mode exclusive.

[Det. Beauregard]

I finally unlocked all the archive items! Now I just need to beat all the scenarios on very hard, then go for S ranks on all scenarios on very hard. It will no doubt be difficult.

I'm missing a few titles between "Jabberwock Killer" and the first Gold Collector one - does anyone know what they are? I'm assuming they're "Anubis Killer" and "Bandersnatch Killer" to go along with the "tough enemies killed" theme, but I'm not sure.

[Archelon]

The first title after Jabberwock Killer is "Indomitable Spirit" for continuing five times. There's one more after it, but before "Well-Off," which you get for collecting 50,000 coins, but I have yet to unlock it.
