[Update] Dark Souls 2: Seamless Co-op - First play test & enemy AI

Hi everyone

I am back home and have started back with seamless co-op development. In this post I'll describe some of the results of the playtest I did this afternoon. Mainly focusing on the bugs and issues encountered along the way.

Overall: It's working "OK" in a sense that it's playable with some issues I can fix quickl...

[Update] Dark Souls 2: Seamless Co-op - Warps and Map loading

Hi everyone

Following the previous post I made a few days ago, I wanted to give some information on some of the behind-the-scenes goings on with the mod development. The post will go a bit more in-depth to the reverse engineering aspect of two elements of the mod I've been working on today.

Hi everyone

Following the previous po...

[Update] Dark Souls 2: Seamless Co-op - World reloading and Bosses

I hope everyone is doing well!

I've been rather focused the past week on pushing past some of the obstacles I've encountered during DS2 seamless development. In this post I'll go over the progress I've made on these issues and where the mod is at right now.

It has been longer than I'd like since the last post but I've been distracted...

Hi everyone!

I finished my exam on Wednesday this week. So now I am available to dedicate more time to the Dark Souls 2 seamless co-op project.

In this post I'm just going to discuss a few more development points in the mod.

Bonfires

I've spent the past few hours today working bonfires into seamless co-...

Paid & exclusive posts

Recently I made my first paid-only post. I understand not everyone is happy being "pay-walled" out of content, however I want to assure people that impo...

[Update] Dark Souls 2: Seamless Co-op (2)

Hi everyone!

I hope you're well - The last update post for this project was all the way back in May of this year.

To clarify, I have been very busy with my personal life since July and as a consequence all of the mod development for my projects have been slow and delayed. However I hope by reading today's update post it will seem a l...

[Update] Elden Ring: Nightreign Seamless Co-op (4+ players)

Hi everyone,

I've been taking a short break to work on a side-project -- Elden Ring Nightreign Seamless Co-op.

As I'm aware that FromSoftware will implement official 2-player game session support, I've shifted the mod more toward being a purely multiphantom (4+ player) mod. Likely stopping at 12 players, and then allowing other modde...

[Update] Elden Ring: Nightreign Seamless Co-op

Hi everyone

I've been doing some more work on Elden Ring: Nightreign. As it's likely FromSoftware will eventually add duos into the vanilla game (hopefully) then seamless co-op will likely have to be repurposed slightly.

Player cap removal

I have removed the player cap for the game. This will hopefully allow fo...

[Discussion] Elden Ring: Nightreign

Hi everyone,

Elden Ring: Nightreign was released today. I played a little bit this evening and managed to get together a functional multiplayer system without connecting to the matchmaking servers (and therefore not needing to run EAC).

The benefit to this of course is you can opt to play with just 2 players (instead of matchmaking w...

[Update] Dark Souls 2: Seamless Co-op (1)

Hiya,

Just to reassure everyone that I am hard at work with the seamless co-op mod for Dark Souls 2.

As I've mentioned before, an overwhleming amount of the work has been reverse engineering stuff (and trawling through lots of x86 assembly) to understand how the game works. Once I had familiarised myself with it, getting sessions to ...
