Dark Souls III - Seamless Co-op v.0.1.1 - Game mod - Download

Seamless Co-op is a mod for Dark Souls 3, created by LukeYui.

Description:

Simply put, the mod allows you to play with friends throughout the entirety ofthe game with no restrictions. With this, it's theoretically possible to play the game from the tutorial up to the final boss completely in one co-op session.

1. If a player dies, they will respawn in the same world at the last bonfire they rested at. The session will not be terminated.
2. Defeating enemy bosses and clearing areas no longer sends co-operators home.
3. All fog walls/barriers that usually restrict the multiplayer zone are gone.
4. All NPC dialogue and talk events will be synchronised
5. When one player rests at a bonfire the world state will reset for all players
6. Game progression events completed in online play will also progress the game in your own world.
7. You can play with 5 other players in the open world.
8. An overhaul to Dark Souls III's peer-to-peer connection system, using Steam's newer networking API

Quality of life improvements

1. Along with core function of this mod, there are a number of quality of life improvements that you might like:
2. A streamlined connection system means that co-operators can join the host from anywhere in the world. So even if you do disconnect, you can very quickly re-join and continue where you left off.

Balancing

1. This mod undoubtedly makes the game much easier. To try and offset this and preserve the game's challenge, mechanics have been introduced in addition to the base game's enemy health pool increases as you would normally get with increasing phantoms:
2. You may customise scaling to your preference
3. If one player sits at a bonfire while others are in boss rooms, those players will be removed from the boss rooms.
4. Dying during a boss battle or invasion will put your character into limbo,spectating other players until either everyone in the party has been defeated, or a player rests at a bonfire.

Invasions

1. If enabled in the ini file (allow_invaders = 1) then other players will be able to join your session as an evil spirit and attempt to kill you and your party.
2. During an active invasion, you cannot warp or use bonfires to rest. Until you defeat the invader and banish them back to their own world.
3. If you would like to invade a player, then use the hairpin item in-game, and you will join a random player's session (within your matchmaking range) and be able to engage in PvP.

Can this ban me?

No. The mod prevents you from connecting the FromSoftware's matchmaking servers, and it uses save files different to the non-modded game. There's no way to get banned using this mod unless you modify it with the intent of connecting to vanilla players.

As this mod introduces new items not found in the base game, it uses a different save file to the normal '.sl2' extension. This means that you cannot access your Seamless Coop save files in the base game, and vice versa. Do not revert mod save files back to vanilla save files, as you will likely get banned.

Installation

Download the mod

Extract the package you downloaded, and move the following files to your Dark Souls III folder (usually in "C:\Program Files (x86)\Steam\steamapps\common\DARK SOULS III\Game")

Edit "ds3sc_settings.ini" to your chosen co-op password

Launch the mod using "ds3sc_launcher.exe"

You don't really have to uninstall the mod. You can use the launcher when you want to play it, otherwise just run the game normally. If you'd like to remove it fully, simply delete the files you downloaded from here.

Use

You must be signed into Steam, and not in be offline mode to use the mod.

You will get the items required to play seamless co-op when you rest at a bonfire.

You and your party members must be running the same version of the mod and the game to play with each other.

I strongly recommend a secure session password, if a player knows your co-op session password then they can join immediately. The mod uses Steam's matchmaking interface alone in order to engage in multiplayer with others. Note that you must set a password to host and join sessions:

One player must host, and other players must join. You must have the same password as the person(s) you'd like to play with (found in the"ds3sc_settings.ini" file).

Troubleshooting:

"seamlesscoop\locale not found which has no fallback"

- You need the locale folder in your Game/SeamlessCoop directory. Check

the mod description page for installation instructions and try again.

Unfixable:

- "Failed, Steam timed out". This is nothing to do with the mod - there is just no connection to Steam. Remember that the servers go down for maintenance every Tuesday.

- The mod can't fix poor internet connections
