Mode 7 Games has released a 55-mission single-player campaign to the Frozen Synapse beta that puts you in the middle of a power struggle between competing factions. The missions are slightly randomized with each playthrough, and run the gamut from escorts to assassinations to robberies. Along the way, a cast of characters will either help or hinder you.
The developers describe the single-player game in more detail here. There’s also a coupon that gives you 30% off the $25.99 price (“STANCHER” is the keyword). If you pre-order, you and a friend get instant access to the beta, including the new single-player campaign, as well as the full version of the game once it’s released later this year.
