Steam Multiplayer - Together in Spire

Description
[discord.com]

Multiplayer comes to Slay the Spire!

What is Together in Spire?
Together in Spire is a mod that allows you to play Slay the Spire with up to 10 friends! You can create lobbies using Steam (one click) or with Port Forwarding, with tons of customisable options. Once you're in a game, you can see other players and attack enemies together with them (or even attack your allies if that's what you choose to do).

The mod is designed to be just added on the top of your mod list as it doesn't change singleplayer at all, and it still allows you to collect singleplayer achievements if it's the only mod running.

What features does it have?
The mod has a ton of new features, some of which are:
- Fully customisable difficulty/game preferences
- Trading
- Reviving
- Player Skins
- MP Achievements
- Multiple game save support

Does the mod support other mods?
Yes! Most of the mods are supported, including new character mods. General rule of thumb is that client affecting mods (like visual changes) are needed only on the player who wants to use them, but the server mods (content mods, card packs, new characters, etc..) are needed on all players. The load order does not matter. If you experience any modded issues, please report them in the discord!

Some mods are too complex or they edit the base game too much so their custom content won't work without patches. This is being worked on at the moment with a lot of progress being made quickly!

If you're a mod creator and you wanna partner to make the two super compatible, reach out to me on discord! :)

Partnered mods
Below is a list of mods with whose developers I have talked with to create custom patches for. This is not a list of 'compatible' mods as most mods atm can be played, some with minor issues.

Say the Spire
Downfall
The Unchained
Ocean's Pencil Case
Marisa: Continued
The Abyssal


Other information

The mod is being actively worked on with new features coming all the time, and there's always bound to be a few bugs.

I HIGHLY recommend joining our discord as there's plenty of important information there:
* bug reporting and crash logs
* setup help channels in case you need assistance
* general chatter

Check out my other mods!


Lastly, if you wanna help support the mod, consider joining my patreon for exclusive testing updates and previews!

And that's about it! Hope to play with you all soon!

Hiii, i was playing this Mod with a friend yesterday and we had loads of fun! We were playing, while both streaming over discord, to turn it into a "real" couch coop experience, with each of us taking turns and I was wondering if it is actually possible to play it as a couch coop, where each player takes turns. I feel like this adds to the "togetherness" of the mod :) anyway, thanks for creating this masterpiece!

recently,a mobile version of Slay the Spire with mod support has been released .Could the multiplayer function be optimized to allow different mobile users to connect?

繁中進入進階10以上就會崩潰，原因出在進階之災(Ascenders Bane)上面.......

This worked today. The password was still not being accepted, but what we did was have one person create the lobby and then invite the other person to game through Steam. That worked!

Can this mod still work?

The Steam P2P hosting doesn't work. However, the Port-Forwarding option works with no issue, so everyone experiencing issues can try that for the time being.
