Valheim

A brutal exploration and survival game for 1-10 players, set in a procedurally-generated purgatory inspired by viking culture. Battle, build, and conquer your way to a saga worthy of Odin’s patronage! https://store.steampowered.com/app/892970/Valheim/

Plus Mod

A HarmonyX Mod aimed at improving the gameplay quality of Valheim. The mod includes several different main features including modifiers to ingame stats of players, buildings and entities and a sophisticated system to build and place objects with high precision and a system to modify already placed objects with high precision. The general goal is to provide V+ as a base modification for your gameplay to increase quality of life, change difficulty or have a better experience in general. The mod also comes with a version and configuration control system for servers and users, allowing servers to make sure that only people with the same configuration are able to join their servers.
