Hello. Welcome back
As far as I know, Steam automatically installs the latest game updates.
All that is necessary, perhaps, is to look for Wormkit modules for the convenience of the game and add them to the game.
https://worms2d.info/WormKitI remember your nickname here, and it seems to me that they played once.
The game is going through difficult times right now.
If you are looking for public games, now the most popular is Kaos Normal; Shopper and Intermediate are played a little less rarely; even more rarely Fort, Mole Shopper, WxW, Hysteria, etc.
Here, at TUS, it’s not very active.
Clans are gradually dying out, a small number of players play in the TUS league, and things are a little better in cups.
I think that if you want to independently study the state of affairs in the game, it is worth watching the activity on TUS.
Peace.
