I am still new at this so I am learning something everyday. The R-sec mines can be placed in very specific places, last night I stuck them in different places on the razorback tires. I don't know if it useful but it sure looks cool.
Huge Freespace fan here!
I wish this game had more elements of Freespace 1 & 2 and a hint more of Battlezone RTS/FPS to it, but it's for the common shooter crowd. We can't have everything.
