Developer Firefly Studios announced the release date of Stronghold: Warlords this weekend. On September 29, the team wants to release the real-time strategy game on PC (via Steam). At launch, players can head into battle against other players or against the computer. Also, a new co-op mode was recently introduced, in which two players manage a single kingdom together.
The big innovation of Stronghold: Warlords is the warlord mechanics - by military or diplomatic means, foreign empires are made to work for your realm's prosperity.
