Further development of original Counter-Strike, but in the direction of higher realism and immersiveness. Reducing the arcade part of the game. Real shotgun spread, real fire rate, view punch on hit, etc. "Iron sights" too :-))) This includes only manual reloading, bleeding, but excludes putting bandages and so ;) This mod makes all the weapons useful, so no more deagle/ak/m4/awp only matches.
This is a photoshop effect I need to simulate in the engine.
It discards blue and green channels, and subtracts from red 40% of green and 40% of blue, then on top of that blend with overlay mode green texture, and then white.
Add some noise on top of that and here's somewhat proper nvg effect.
