Firefly Studios announces that a new free DLC pack is now available for Stronghold Crusader 2 on Steam. Here's word on what this brings to the besieged strategy sequel: "The new expansion adds Sandbox siege invasions, an easy AI mode, six new maps and faction selection for single-player campaigns." Here's a gameplay trailer and here's more on what this adds:

• Siege Invasions – Designed to beef up the free-building Sandbox mode, invasions allow players to find out just how impregnable their mighty castles are by launching increasingly powerful attacks against them.
• Easy AI Mode – A popular request among those new to the series, this easier difficulty setting makes the AI less aggressive in the game’s punishing Skirmish Trail missions.
• Faction Selection – Another oft-requested feature, players can now select between Crusader and Arabic factions in Skirmish Trail missions.
• New Sandbox Maps – Two peaceful new lands on which to build the ultimate castle, before pummeling it into the sand with wave after wave of AI sieges.
• New Skirmish Maps – Four new battlegrounds ready to be marked with the the enemy's blood, online or offline.
