Have played 2 maps of the seven, the campaign is a nice Sunday couple hour one, i will re visit the other chapters. Some sections like when you turn the three valves to open a door to just to loop back to a point you just were at seems a little odd. a little more linear, with a couple arrows here and there, and reduce the amount (a little) of dead , blocked doors or dead ends. map runs nice with no errors.
Heavy detail, Long, well made.
