Armored Core Coop Mod
Unofficial online co-operative multiplayer mod for Armored Core 6: Fires of Rubicon
www.nexusmods.com
The mod enables playing through all of Armored Core 6 in coop - with up to 6 players at once. It's as simple as opening up a session and inviting your friends through Steam to play with you!
The mod runs on a separate savefile and without EAC - so there's no risk of getting banned in the main game. Latency issues tied to EAC are also nonexistent within the mod. However, matchmaking is only available between modded players.
Players can adjust the game to their liking - enable or disable friendly fire, increase or decrease the enemy scaling, or other options available in the configuration file.
If players wish to use other mods in conjunction with Armored Core 6 Coop, matchmaking will only be within their specific mod loadout. This allows for a coop and PvP scene within each respective community.
Regarding the last point -- players can also invade each other.
