TO DO (Among others)
-Further testing of the bombspots with good awpers & smoke strategies
-Change middle door for a breakable model
-Observe lightmaps in order to improve shadows and reduce filesize
-Revise hinting, as in some places it may have aged
-Design and add new signs for bombspots
-Improve some textures (mostly specular and ssbump)
-Improve 2d & 3d skybox
-Further details (v.g snow on few props) & light improvements in certain areas
-Further clipping to make movement smooth
-Navigation mesh for bots

I've already noticed the snow on crate A stucks with the player when crouching close to it. Will fix in the next update, after a game test.
