GA-Source has posted an interview with the people of SingleTrac, who are currently developing Rock, their upcoming first-person action hybrid. The article goes into detail about the game's storyline, features, gameplay, engine, and more. Here is a bit describing the game in a nutshell:

Rock is a squad-based action/strategy game that emphasizes the whole theater of combat. Players play as a squad leader and have to select and manage their squad to accomplish mission objectives. Rock has squad mates and unit types. The strategy components come into play in how you match up the two and then command them in the mission. Squad mates have varying abilities and you need to use them in areas where they are talented. It really matters how you organize and outfit your squad.
