Medieval RTS Stronghold 2 has been re-released on Steam in an edition that reboots the game's dormant multiplayer mode, revamps the visuals and adds Steam Workshop support.

The 2005 game was only previously available on Steam via The Stronghold Collection, but its multiplayer servers were shut down in 2014. This standalone version—called Stronghold 2: Steam Edition—allows up to eight players to compete online on large maps as they try to wipe out their opponents' armies in Deathmatch or kill high-value targets in the Kingmaker mode.
