Breakmines, the next in my series of breakable maps, is taking place in (omfg you guessed it) some mines. Completely underground, mid-level starting area. I suppose it will be rather similar to Red Faction's levels in that you'll be digging from one room to the next. I also want to attempt a drivable mine cart and more. More to come soon.
