Some new Metal Gear Online details can be found in the Metal Gear Solid V: The Phantom Pain Web Manual on the official website. First of all, here is a screenshot that shows the game’s HUD.
Furthermore, there are some details on game modes and matchmaking. The game will begin in free roam, after which the player can either improve his skills at a shooting range or go into a match using the iDroid. From the manual:
METAL GEAR ONLINE begins in free roam, during which no online battles take place.
Accessing the iDROID during free roam allows you to join online versus matches as well as perform character customization, etc.
You can also access a shooting range to polish your skills between battles.
Select the iDROID’s [MATCHING] menu to join versus battles.
- [AUTOMATCH] Select your preferred mission and automatically join a match.
- [CREATE MATCH] Configure your own mission list and create a match.
- [SELECT MATCH] Select a match created by other users to join.
Metal Gear Online will launch on October 6th for consoles and January 2016 for PC.
