Highly recommend this wargame challenge from over the wire. It makes you think and also feels like hacking. Youre just using linux commands to find passwords but the skills transfer to heaps of usage across systems. It can be a little beginner-ish though.
I play PlateUp with a friend, we started on remote play while I wasnt sure if I liked the game. It had issues where if the window lost focus, I’d crash and the entire game session was lost. Anyway, I bought the game and have never had any issues since. Its super fun!
