Steam Multiplayer – Together in Spire
Conquer the Spire Together with Together in Spire
Prepare to experience Slay the Spire like never before with Together in Spire, a revolutionary mod that brings cooperative multiplayer to your ascensions. Forget solo climbs; now you can gather your allies and face the Spire’s challenges as a team of up to ten players.
Embark on Cooperative Adventures
Together in Spire seamlessly integrates multiplayer functionality, allowing you to create lobbies through Steam with a simple click or utilize traditional port forwarding. Once your group is assembled, you’ll be able to see your friends navigating the treacherous floors alongside you. Coordinate your strategies, combine your card synergies, and unleash devastating attacks on common enemies. Or, if your friendships are particularly robust, engage in some friendly (or not-so-friendly) PvP by targeting your allies!
A Mod Designed for Modularity
One of the key design philosophies behind Together in Spire is its minimal impact on the core single-player experience. The mod is intended to be added to your existing mod list without altering single-player gameplay. You can even continue to earn your single-player achievements as long as this is the only mod active.
Feature-Rich Multiplayer Experience
Together in Spire boasts an impressive array of features designed to enhance your cooperative sessions:
- Fully customizable game settings and difficulty levels to tailor the challenge.
- In-game trading system to share valuable resources.
- Revive mechanics to bring fallen comrades back into the fight.
- Player skins to personalize your appearance within the game.
- Dedicated multiplayer achievements to unlock with your friends.
- Support for multiple game save slots.
Extensive Mod Compatibility
Venture into the Spire with your favorite mods! Together in Spire is designed to be highly compatible with a vast number of other Slay the Spire modifications, including those that introduce new characters. Generally, client-side mods (like visual alterations) only need to be installed by the player who wishes to use them. However, server-side mods, such as those adding new content, card packs, or characters, require installation on all players’ machines. While most mods work out of the box, some complex modifications may require specific patches for full compatibility, and development is ongoing to expand this support.
