hi
i like ur map, cool optix, good gameplay.
i especially like ur spawning. holes in the ceiling are the answer to players holding a single room over 10 waves. one scrake dropping from such a hole can be a good cure for such cheap behavior.
i remember one room in the basement with only a crawler, stalker hole in a shady corner. make holes in the ceiling in regular distances like airducts for a ventsystem. in addition with short spawndistances to the player there is no sitting but only run and gun.
keep up the good work.
