No revenue estimate for PSN — its rating/review counts don't calibrate to sales the way Steam's do. The Steam version is estimated at $3M — a different platform, not this one.

Styx: Shards of Darkness

Styx returns in a new stealth adventure! Hired for a critical mission, explore and master huge open environments as Styx, alone or in coop with a friend. Assassinate or sneak past enemies – Humans, Elves and Dwarfs – but also much more fearsome, colossal creatures, and experiment with the new array of lethal abilities and weapons in your goblin assassin's arsenal. Spend experience points in assassination, infiltration, magic, to learn new skills and improve abilities. Explore, recover valuable artifacts and ingredients to craft deadly traps and useful items, and create clones of yourself to deceive your enemies! Online features may be terminated at any time.
