Alexandria
Alexandria is a broad utility library for Enter the Gungeon modding, built to make the mod creation process easier through a shared dependency packed with helpful code, APIs, and development tools. Rather than serving as a content mod on its own, it acts as a foundation that other mods can rely on for faster, more flexible development.
It combines older and newer systems into one convenient package, giving mod creators access to a large set of features for custom characters, enemies, items, rooms, shops, breakables, lighting, translations, dodge rolls, and more.
