DISCLAIMER: This entire guide is a spoiler.

The Top Uplink Agent is dead. In a previous save file, you remember being given a key to the ARC Central Mainframe to log in and see what ARC is up to, but you remember it didn't work. So you think about your past training on network logs - what exactly is hiding behind the early-game ARC Central Mainframe?

Let's find out. Follow me!

This is basically a Perform a Passive Trace mission from my other guide at:
http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=221998541

Finding RevelationCoreV0.7 involves hacking several systems, guided by access logs, to counterhack the hacker of the ARC Central Mainframe. It will require extensive knowledge of logs. This mission has no email, and can only be "accepted" anytime between recieving the news article of the death of the Uplink Agent and upon recieving the autosend email from the dead agent.

Do note that upon recieving ANY relevant email, the routed logs will be deleted from ARC Central Mainframe and the Agent's Personal Computer's IP Address will no longer be valid and will give you the page Uplink gives you if you type in a wrong IP address (Source: Onlink), which reads 404 Error.

For this missions, you must have the following tools, though more can help you. Tools may vary for all System Traces, for you never know what you have to hack next.

• Password_Breaker v1.0
  
• Trace_Tracker v2.0
  
• Log_Deleter v4.0
  
• HUD_ConnectionAnalysis v1.0
  
• Firewall/Monitor/Proxy Bypasser v5.0
  
• Voice_Analyzer v2.0
  
• Decypher v3.0
  
• IP_Lookup v1.0
  
• Log_Undeleter v1.0
  
• File_Copier v1.0
  
• Decrypter (Varies in level; it is the encryption level of RevelationCoreV0.7)

This hack can be perfomed using any Gateway, with any Hardware.

At any time during the first ten days of April, you will see this news article. Consider this your starting gun; if and only if this article exists to you, the hack is possible. Write down the date and time of this article, you will need it later: 13:00 8-4-2010 (NOTE: This is a variable; your date and time will NOT be the same as mine).

However, where do you start? You don't have a mission email, so you are directionless. Only if you have played through the game before will you know where to go. Remember the email you recieved on April 14th? Remember the server it told you to go to?

Yup. You're hacking the Andromeda Research Corporation (ARC) Central Mainframe (CM).

So head on over to InterNIC..
..and pick up ARC Internal Services Machine (ISM)'s link. You will see why when we hack it.
Now, since this isn't a real mission, you will be without the guidance of green mission links. Here's a guide on how to be able to navigate using your Gateway screen. See those buttons to the right of your links? These can be toggled to three states, with one overriding state.

• State 1: The link will display as white on the map.
  
• State 2: The link will display as orange on the map.
  
• State 3: The link will not display on the map, unless it is part of a bounce path - where it will cease to display if removed.
  
• Mission-Required State: All mission-required links will display as green, unless it is in State 3. This is overriding of States 1 and 2

So after putting ARC ISM in State 2, connect to it.
You should know how to hack an ISM, assuming this is at least your second playthrough. However, if you don't, check out my guide on missions:
http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=221998541
Why are you hacking the ISM? You ask? Open up the links and you'll see..
..all of ARC and Darwin Research Associates links (DRA happens to have 'arc' in it's name. Ironic if you know ARC Mission 2)! Add the ARC Public Access Server (PAS) and ARC CM.

After this, directly connect to the PAS - this can be done from the links screen you're already on, if you want to. Just make sure to clear your logs either way.
After hitting the button on the first screen, you will see two contacts with an 'Add link' button next to their phone numbers. Hit the button next to the ADMINISTRATOR contact.

Disconnect, then directly connect to the phone number's Voice Phone System (VPS).
Run your Voice_Analyzer v2.0. If you're unsure as to how to use this, check out this guy's guide (be sure to check the comments for more information):
http://gtm.steamproxy.vip/sharedfiles/filedetails/?id=123122050

Once you have the admin's voice, save it, and disconnect. As long as you saved it, you do not have to leave your Voice_Analyzer opened. However, if you only have Version 1.0, you MUST leave it open - for you cannot save.
Bounce through at least one ARC-owned system to connect to the ARC CM, which I assume you marked in State 2. Why not use the ARC ISM you probably forgot to unmark from State 2?
Now, hack the CM. You'll need a Password_Breaker for the password verification, any level Decypher for the encryption cypher, and the Voice_Analyzer playback for the Voice-Print Authentication. To keep your monitor from noticing you, hack the password last.
Once you do that, your trace will begin and you will be at the main menu of the CM. You're after the logs, so go to 'View Logs'.
This is arguably the one time in the game you actually get to use this tool: the Log_Undeleter. This tool is the reason why any system that isn't an Early-Game ISM can easily see past your crappy Log_Deleter v1.0-3.0 deletions.

Use the Log_Undeleter on ALL three logs timestamped at 13:00 8-4-2014. For some reason, the IP address responsible for the deletion of RevelationCoreV0.7 is missing. However, there is a connection and disconnection from an IP address at the same time and date.

Using the Log_Undeleter will ensure you're after the right IP address. Once you have verified that the IP you are shown (which is 992.580.239.356 in my example)
Now bring up your IP_Lookup. Enter this IP exactly as it is shown, and then hit GO.

Your IP_Lookup will then give you the name of the next hop in the bounce path, which is the Biogenic Tech. CM. Do the same thing you did with ARC:
Add the ISM, add the PAS link, call the admin, record the voice..
Bounce through the ISM, hack the CM's security, go to View Logs..
And you should arrive here. First, undelete the log at 13:00 at 8-4-2010. Then,
VERIFY that the log's next point is the ARC CM. This will make sure that you are following the correct path.
Then enter the next IP in the same log into your IP_Lookup, and then..
Do it all again!
Now, upon looking at the logs for this CM, I did not have a routed log immediately. In the picture above, I simulated this by putting a log on top of the other log (I forgot to screenshot my Undeletion). Run the Log_Undeleter on the log at 13:00 at 8-4-2010 to reveal the routed log.

I verified that the second IP led to the Biogenic Tech CM, but the first IP..
..informs me that I have reached the last leg of the routed logs. When Performing a Passive Trace, your mission is complete when you reach the IP of a Personal Computer.

However, we're not quite done yet. Disconnect from this CM.
Now, you do something you will only have one chance to do in this game. Directly connect to Richard Boyer's Personal Computer. This is the only PC you can enter in the game.
You will be greeted with one password screen. Your Password_Breaker will fail to work. The only way to know the password will be to recieve the email from the agent in a playthrough.

What? What are you looking at me for? Play the game at least once before doing this! I will not spoiler the password, and will not allow the posting of the password in the comments. I will give you a hint though: The password is in the email you will never recieve in this save file, from the dead agent.

UPDATE: You can use the Password_Breaker at this screen.
Once the password is entered, you will automatically enter the main menu of the PC. Head over to 'eMailz'.

You will see one email that reveals that Mr. Boyer liked the magazine Hacker Monthly. How wonderful. This isn't important at all. Ignore this email.

However, the second email is the email you will never recieve on this save file. You may read it, but it does not have the attached login information or the link to ARC Central Mainframe.

In order for your hack to matter, you must cancel the email. Hit 'Cancel' underneath this email. Because of this, ARC will only make contact with you and Uplink will never be warned about the Revelation Crisis until Arunmor either recieves a complete copy or ARC destroys the Arunmor ISM.

Under 'FileZ' is the file that you have been hunting for, RevelationCoreV0.7 - a trophy for completing the hack. Copy it over,
And decrypt.

Upon completing this mission, you will recieve an email before April 14th from ARC congratulating you on your impossible hack.

So what exactly does RevelationCoreV0.7 do? Absolutely nothing! It's simply something to chase down the routed logs for.

The only part of your hack that ARC will care about is the canceling of the email that will incriminate them. I know this because I submitted to watching a B-rate movie with my mom while in a Late-Game ISM on a Frame a User mission. The computer was destroyed, along with RevelationCoreV0.7. The email's tone remained the same as if the mission were completed.
