Totem Games has released a free add-on for the tactical naval sim Ironclads: High Seas.
Armchair General writes: "Totem Games's Ironclad series just keeps growing in response to gamers' wishes. The first version was turn-based and focused on littoral and harbor clashes. The turn-based engine produced some strange situations such as ships sailing past opponents without receiving fire. The next version, Ironclads: High Seas, fixed that problem with a real-time engine but didn't afford players much latitude in creating scenarios. Totem has responded not only by releasing a scenario editor but also by including two new ships for this game of naval combat in the American Civil War."
