Development on map 10 One of the most hardest maps in the game is now being developed
Posted by lightningterror on Oct 7th, 2012
I would like to inform every one that development on the 10th map is underway. The preview image you see before you is a laser room , something like in the Resident Evil movies :D , and yes i will try to add the lasers and some awesome scenes in this map.
This map will be one of the hardest maps to script and one of the hardest levels to pass in the game.
From this point on there will also be new zombie like enemies in the game and will be though to kill.
