Add tips

The game should sometimes display tips in chat such as:

• type /modules to list modules
• general gameplay tips
• specific modules tips
• ...

with the move to having resources on the server side, I feel like it could be a sgui popup that shows when a player joins the game. alternatively/additionally have an item added to the players inventory in the load screen and the drop in sequence that they can right click to see the modules.

Personally I think uhc already has a lot of text to chat so adding more will likely be missed by players

Modules are already displayed in a GUI right before the game starts. There is not much text mid-game, especially on longer runs. I think it's good to have some random tips around, and let players maybe disable them.
