For a long time in ARMA 2, I strayed away from making missions in ARMA 2 on Chernarus as it had barely any CQB gameplay with most buildings being un-enterable and all. Chernarus+ remedies that nearly completely as well as expanding the map.
It would be wonderful if Chernarus+ was available to all ARMA 3 owners to play with for not only a sense of nostalgia, but also bringing back one of the most memorable maps in the series, its already been roughly done in ARMA 3 just it has its errors like incorrect materials and crashing.
