About the game
You play Styx, a goblin assassin who sneaks into an elven city across nine missions. Most of the time you hide in shadows, watch guard patrols and pick a route over ropes and ledges. Open fights are a last resort, so you take guards out quietly or slip around them. Mission results pay for new skills, and you can craft traps.
Every mission can be played in co-op by two players online. A friend can join a mission you are already playing and leave again whenever they like. A second player helps with distractions and hiding bodies, but two people also mean twice the chance of being spotted.
It is slow and careful. You talk through each guard before you move, and you retry sections when one of you is seen. It suits two patient friends who like to plan.
