Frozen Synapse is now available from the Frozen Synapse Website and Matrix Games, as was promised earlier this week. There is also an extensive The Making Of Frozen Synapse feature on SMTG (thanks Cliffski) with all sorts of background and other details about this indie simultaneous turn-based strategy game. Here's a bit from the release announcement:

"Each match immediately places you in an intense tactical situation: there's no waiting around for the fun part. Blast a hole in a wall with a rocket and then send in your close-range units, or take a stealthy approach and set up cover with a sniper: your approach is entirely down to your own creativity. If you can predict your opponent's moves, you can win the match: this game has been crafted so that superior tactics will triumph! Once you've outwitted your opponent with a series of perfect turns, watch your Global Ranking climb and export the results to YouTube instantly!
