“Red”, an expansion pack for the turn-based strategy game Frozen Synapse, has been been released and offers two-player co-op, a riot shield unit, a new “kill the hacker” multiplayer mode, three mutators, a 15-mission single-player campaign, 10 single-player challenge missions, new music from nervous_testpilot, and “Red Mode”, which lets you play the game with red environments. The $10 expansion is available from the Frozen Synapse website or Steam (Steam keys are provided even if you buy directly from Mode 7 Games).
On top of that, the game has received a free update that adds Hotseat Mode, timed turns, and non-randomized multiplayer maps for competitive play. See the Mode 7 Games blog for more details.
