Tactica Online Announced on IGN is a story overlooked yesterday (thanks Mike Martinez) revealing plans for Tactica Online, an MMO turn-based strategy game in the works at Australian developer Imaginary Numbers. The game is slated to launch in Fall of this year, offering gameplay set in the days of Leonardo da Vinci. Here's a bit:

In Tactica, players will control a team of characters with customized skills and abilities. The developer describes building a combat-worthy team as similar to building a deck in a collectible card game. The game will offer action in the form of missions, Tournaments, and Campaigns, the last of which affect the game's primary story.
