How if you would put those all OC`s behind the boxes on ground level? You have 2 entrances to that room from the rine side of the map acidic and the long corridor(whats`s that name?
Often this would lead to marine trying to rush the hive and realizing too late that he`s gone. After few times the rines might be smart enough to put the pg on the upper level but still they would had to fight the aliens thus moving and eventually falling down to be shredded?
I really like this idea how about you guys and especially you Asal, due beeing the official NS forum
