MCCS - new Multiplayer content

Excellent. Open the advanced map editor (a quick Google search will show you how to switch to advanced mode), select the Table_DBArtefact_ArtefactEffect table in Resource => Select Tables. In the new window, open the GameMechanics => RefTables => Artifacts folder. Double-click to open and go to the properties. Expand the list by clicking on the +, and look for artifacts numbered 173-250, expanding each one with a plus sign. There you will find the properties. I think they are fairly intuitive. In Shared, you will need to create a new shared resource (click on a row => new), and in the properties of the shared resource (after creating it, click on a row => three dots), select a model, animation (if needed), and effect – these will be displayed in the game and the editor.

In Icon, create a new texture with the settings Texture Type TEXTURE_2D, Convert Type CONVERT_ORDINARY, Texture Format TF_8888. In SrcFile, select a texture from the game folder/Complete/, and after selecting it, right-click on the texture name on the left in the file tree and click Export. The rest, I think, doesn't require further explanation.
