Frozen Synapse came out in 2011 and is one of the most tactical and intelligent games I've ever played. The breadth of information you need to take into account before committing to a move is insane! If you didn't account for that grenade launcher to fire around the corner, then you might have just sacrificed you entire team.
Mode 7, the developer of the original game, is teaming up with Double Eleven to bring the tactical goodness to both the PlayStation 3 and Vita some time this year. According to the blog, Frozen Synapse: Tactics will not be a straight-up port of the original game and will get the "complete Double Eleven makeover." However Mode 7 also wants to "reinvent the game’s aesthetics and interactivity," which I'm not too sure about. I thought the game's bare-bones aesthetic was rather charming, and fit the theme quite well.
