Description Endgame is the way I like to play and it gives a more traditional shooter feel while leaving other aspects intact. Some mutants are easier to bring down (more realistic). Aiming is significantly better (not as realistic). Enemies no longer spot you from across the map, and sneaking up on them is easier, They also have the same limits of sight in darkness as you (human AI only). Weapon damages have been increased significantly to the point of overkill. Do not run in like Rambo, you will die very quickly.
Again this is the way I like to play. I made an Endgame mod for other games including Shadow of Chernobyl, but this is the first one I'm sharing with others.
If this does not suit your play style feel free to tweak it to your liking (or use something else.)
I enjoy the S.T.A.L.K.E.R. games immensely, The immersion and gameplay are
what I've been looking for in a shooter for very long time. That said I never liked
the fact that you had to wait 5 minutes for your crosshair to focus while enemies
with perfect aim hit you with a sawed off shotgun from a mile away. I also had serious issues with the fact that I had to empty a whole clip of ammo into one Bloodsucker/ pseudo dog etc just to bring it down.
At the end of the day, mutant yes, but its still flesh and bone, and no amount of radiation grants armor plating to an animal. :p.
