Secret Mission: Christmas Modpack 1.21.1

Secret Mission: Christmas is a Minecraft modpack designed for a Christmas-themed adventure. It features dungeons and enemies alongside numerous Christmas-themed mods. These additions are also suitable for building enthusiasts, allowing for the decoration of structures. The modpack creates a snowy world for survival, with new snowy blocks. While generally friendly in theme, survival becomes more challenging at night, requiring players to secure their homes in addition to decorating them. The modpack includes several Christmas mods such as Christmas Culinary, Music Discs, Mama's Merrymaking, and Christmas Colonies for Minecolonies. It also incorporates minor biome improvements like Geophilic and multiplayer-focused mods such as Security Craft, PlayerRevive, and Emotecraft.

This modpack is not supported on servers due to the inclusion of Primal Winter. To play on a server, users must remove Primal Winter from the client installation, as it has not been added to the server pack. The creator is awaiting an update for Primal Winter to resolve this incompatibility. The modpack is optimized and shader compatible, thanks to Sodium and Iris. However, due to snow particles and the added mods, it may not be playable on all devices despite the included optimization mods.
