Patch 1.06 for Metal Gear Solid V: The Phantom Pain rolled out earlier today and with it came a number of FOB updates and minor gameplay tweaks. However, users on reddit soon discovered that replaying  a certain mission after the patch allowed for a new interaction with one of the game's prominent characters. These details could be considered spoilers for Metal Gear Solid V: The Phantom Pain so consider yourself warned.

To complete the story in MGSV players had to exile the mute sniper Quiet from their Mother Base. Doing so would make her unable to be used as a buddy in any continued playthrough. Now, by replaying Mission 11 "Cloaked In Silence" where players first met Quiet, seven times, Quiet will return to Mother Base and be available as a buddy character regardless of how much of the game you have completed.

Here are the full patch notes for update 1.06 which surprisingly does not include any mention of the Quiet update:

New look for the PF Rating screen! PF Rating-related event also coming soon!

The November update features changes to the user interface of the PF Rating screen, such as revised displays of the factors contributing to your PF’s overall strength. With this better understanding of your PF’s status, you’ll have all the necessary intel to get the most out of FOB missions, etc. Also, look forward to a new PF Rating Event scheduled for November 2015!

Get ready for a new level of gear with Grade 8 and new Online Development Items!

The update also features new weapons and items to help turn missions in your favor. Following on from the addition of the current highest development grade (Grade 7), you will now be able to develop Grade 8 equipment as well.Grade 8 equipment are also classified as new online development items, or items that continue the development process even while you are away from your game system or PC. You can also use earned MB Coins to shorten the development time.See the following for a look at some of the new equipment.

Protect your FOBs from invasion! New security devices added!

There's rarely a chance to relax when your FOBs could come under attack at any time, but now, some of the best ever security devices are here to put your mind at ease. All of the newly-added security devices are online development items, so their development will continue even while you are away from your game system or PC. You can also use earned MB Coins to shorten the development time.

"Anti-Reflex Research" added as a Medical Team unit function!

The unit function "Anti-Reflex Research" is newly added to the Medical Team. The higher your Medical Team’s level gets, the shorter an invader’s Reflex Mode time will be.

"Stealth Mode" will now have an effect in FOB infiltrations! Go unseen by enemy searches!

While infiltrating a rival’s FOB, using Stealth Mode (pressing the Action Button while prone) will cause your Predicted FOM (field of movement) to disappear from the defending player’s iDroid, and the defending Intel Team will also be unable to search out your general location.

Newly unlocked FOB 3 option

You can now give your PF a huge boost by constructing a third FOB. With the resulting major increases in max. staff capacity, you can look forward to unit functions being upgraded across the board.

For all newcomers to the game: Rookie and beginner functions expanded!

From now on, it will be easier for players to obtain the "Chicken Hat" and "Lil’ Chick Hat" (awarded to those who repeatedly fail a mission). For those having trouble with a difficult mission, these items will be a significant help. Also, a "Rookie Assist Function" is added to Espionage Ratings (the results of FOB Missions). This function prevents rookie players from losing Espionage Points when they fail at FOB invasions or defenses.

Other additional refinements have been made to various elements of the game including balance adjustments and bug fixes.

・ The top rankings for PF Rating and Espionage Rating will now be displayed. ・ Whereas until now only resources in your offline inventory could be sold, from now on your online inventory can also be sold. ・ The issue with certain DLC uniform equipment not having its advertised effect is now fixed. ・ In-game notifications of events and other news have been improved.
