This is currently an experimental build so expect a few bugs.

(ver. 2.0)

What's new in ver. 2.0: (Updated on 5/23 @ 4PM ET)
- Increased the player count to support 127 players (note this has only been tested up to 15)
- Added PvP, PvE, and boss rush modes. You can access these with the shrines at rountable hold and the Limgrave and Caelid areanas
- Fixed some inconsistencies with packet order
- Modified the way clients initially connect with each other
- Removed the Varré quest line skip
- Added visual effects to rot
- Changed some mod icons
If you'd like to use this experimental version, then you must replace **ALL** mod files *including the launcher*. A clean install of seamless co-op is strongly recommended.
Not compatible with mods; The seamless co-op launcher is required for functionality. Wait for stable release if you require usage of other mods. 

Info about the mod:

- Mod which removes all multiplayer boundaries and allows for connections to persist after death.

- Play with friends from the tutorial to the very end of the game, with synchronized progress, and no re-summoning or interruptions.

- Enemy scaling is fixed (it didn't work at all previously). It now mimics Elden Ring's (25%/50%/75%) buff on enemies for 1, 2, and 3 co-operators respectively.

- Voting enables synchronized fast travelling in the game. All players in the session must agree to warp to a specific destination. Once the vote passes, all players are warped at the same time.

- Map waypoints are now synced with other players in the session, making it easier to communicate where you'd like to explore or areas of interest.

- Evergaols, portals, etc. now all work correctly and affect other players in the session allowing you to tackle usually restricted areas in multiplayer.

- When dying in a boss fight, you will be unable to re-spawn and enter a spectator mode until either the boss is dead or every other player dies. This lets bosses keep their challenge while allowing you to stay together in a multiplayer session.

- A stack-able debuff mechanic called Rot Essence has been added. It is acquired on death and can be removed when resting at a bonfire. There are currently 3 varied effects that can stack both with others and themselves.

Frequently Asked Questions (FAQ's):

Q) Can the mod get me banned?
A) No, the mod doesn't connect to the matchmaking servers and does not use FromSoftware's online services and therefore you can't get banned for using it.

Q) What is the player cap?
A) The maximum player count in a party is 127 (1 host + 126 guest players). Only tested up to 15 player simultaneously in ver 2.0.

Q) Are there invasions?
A) No, there are no invasions.

Q) How do items work?
A) Items are unique to every player. If boss drops a talisman pouch for example, everyone will get it. The same applies to items found in the world and enemy drops.

Q) How do sites of grace/bonfires work?
A) If one player sits at a site of grace anywhere in the world an enemy/world reset will occur for every player. If a player is fighting a non-open world boss at this time, they will be placed back outside the fog wall and the fight will be reset.

Q) Is progress shared?
A) Yes progress is shared. But it only applies to actions you do whilst in a player's world - for example if you start a fresh character and join a player to kill an end-game boss, only that boss will be dead in your world and you won't inherit all of the other player's progress they had before you joined.

Q) How does it work with the anti-cheat?
A) It doesn't, the mod uses a separate launcher which runs the game without launching Easy Anti-Cheat.

Q) Can I use other mods?
A) Yes, however for regulation / param file edits everyone in the party must have them active in order for them to be visible. (e.g. if just 1 player uses a randomizer, it will only work for that player). Also, not in experimental build 2.0

Q) Does this worked for cracked/pirated games?
A) No.

Q) Isn't this just easy mode?
A) Not necessarily, while co-op play does make the game objectively easier, it's also a completely different way to play the game. There are plenty of "easy mode" mods out that that just give you high health/damage. This mod will be easier but is made in mind of those who want to play the game the whole way through with friends. It has been designed with fun in mind as opposed to reducing the challenge.

Q) Can I modify or redistribute this mod?
A) No.

Q) Can I use my save game from the base game?
A) Yes[/b]

Fang a écrit :

Set the coop password in SeamlessCoop\cooppassword.ini
The host must use the Tiny Great Pot to create a session.
At that point, the other players can join using the Effigy of Melina.
You should spawn in at a point nearby the host. Any player can leave at any time using the Separating Mist
- If the host uses this item, the session will be disbanded and all players will disconnect.

ensha reappeared after he got defeated as an invader, and roderika is still located beside the fireplace even after she already relocated near hewg when I'm playing coop with my friend, but returns to normal when playing solo.
is this a known bug?

[Handshoe]

Is there any way to restore a seamless co-op save to be used online again?

Just deleting the mod and reverting the save file extension make's it so i have 4 "unknown" item icons in my inventory that cant be deleted.

My best guess is you would have to use something else to edit your character's inv. and remove the items while in offline mode, but I'm not entirely sure if that makes the save safe to use again either. You're probably better off accepting that Seamless saves were never meant to be ported to vanilla

same here. As well as the Fingerlady at the roundtable not being present for both of us in coop.

[scrafty the kobold]

still the best mod for this game. this game is so much fun playing with friends and this mod almost feels perfect at making it feel like its meant to be in the game

[MacCadley]

This mod is very fun to play with your friends. It actually makes you feel that the game should be done in this way from the beginning. Still I've got troubles with enemy's HP scale: when I'm playing with 1 friend - everything looks ok, bosses can be killed, HP looks fine. But when we start playing with 2 other friends (So it's 3 of us) - HP scale goes off. For example: Fire Giant. Originally he has around 40k HP. But during our tries we cannot kill him for several hours. I tried to kill him on singleplayer - he dies really quickly. We tried to kill him with cheat - my friend hit him with 500k damage - it took only a half of his HP. According to mod's description - his HP should be 80k, but it's definitely higher. I noticed that bosses' HP goes too much higher on Starscourge Radahn, probably something with scaling, but I can be wrong

[CoffeeBreak]

The mod is borderline unplayable at times, but it made the game WAY more fun. Friends and I would look for each others summon signs for like 10 minutes, finally get everyone in, then someone would get immediately dropped from the session. Then suddenly we can find their summon sign and we're running around in circles screen sharing and trying to get them back. In the middle of this someone invades with a +10 weapon their friend dropped for them and proceeds to dunk us. This mod made the experience so much more fluid and fun.

Though as a fromsoft fan since darksouls 2, I do kind of miss the funny invasions I would get where someone thought they could parry my mega axe and would proceed to lose 3/4 of there health, then they roll my subsequent 3 swings, assume I'm out of stamina, only to find out I had 2 more swings and a hard on for them. Or when an invader would help me find important stuff or we'd just mess around, the mod takes that away, but I finally got to play with my friends and get them into the soulsborne series. 10/10 mod

Your first paragraph seems like you and your friends problem - I haven't had that much trouble with it at all. One of you need to fix your connection.

Hi, I've just read your comment on this mod. It's seems you have poor connection sometimes. Yeah, it's true there're bunch of bugs during your play, but in fact - you don't have to search for summoning signs, as your teammates automatically join, as soon as you open your worlds. Got invaded? That's sound off, as this mod turns off online mod, so you can no longer being invaded and invaded as well.

I believe he was describing what used to happen before the mod came around with regards to searching for summon signs and invaders.

There are a few desync issues at times but for the most part, it shouldn't be nigh unplayable even sometimes. Ask others have suggested, check your internet connection. Ethernet rather than Wifi if possible.

[DarkerThanBlack]

Draconic Tree Sentinel before royal capital has lock on problem after a while in a fight. This is still happening from one of the first versions of the mod. Also volcano manor has another big sync problem, I ve finished the game few months ago with this mod, Now I am trying to finish it with my girlfriend with literally same save file but sync/lock on issues remain. I am grateful (wanted to say graceful :D) but especially this two problem make it unplayable sometimes. Thanks for the state of marika fixes.

[Meovyle]

A boss died instantly when we went inside the room.
The boss that drops the "assasins crimson dagger"
Anyone know whats up with that

[Meovyle]

When joining a friend it says "ensared in a trap" and now the joiner are stuck in a loading loop.
