CounterSide is fully free and single player now

The Stop Killing Games folks will love this.

CounterSide is a gacha game. It died on August 26th this year. However, some modders have provided infrastructure to host your own local server, so it can still be played.

You can also use console commands to give yourself however many gacha pulls, other currency, or gear you want. The story is fully playable, so the game can be treated like a single player RPG.

Some of the gamemodes don’t work right (I hear Dive is broken), but the important stuff like the main story, side stories, and combat work fine.

The infrastructure that handles launching the server is here, though you will need to grab the assets (which the infrastructure calls a frozen client) elsewhere. The non-Steam variant seems to work best, though YMMV.
