This is a compatibility patch that makes the best weapon mod for CoP (Arsenal Overhaul 3.1) and the best dynamic hud mod (CoP - HUD Reworked 2.0) run together. Beside Atmosfear 3 + Absolute Nature 4.01, and surround sound, these great mods all together provide a truly refreshed experience for all S.T.A.L.K.E.R. fans. Credits go to the mods creators, i have just put the little patch together (still WIP, if you find a bug please report it back and i will try to fix it).
Over a clean install of S.T.A.L.K.E.R. Call of Pripyat, patched to version 1.6.02:
1- Copy the content of Arsenal Overhaul- AO 3.1 (link below) to game dir, following the install instructions of the mod.
2- Install Atmosfear 3 for AO 3.1 (the one included as an optional addon in the AO 3.1 pack).
3- Copy the content of CoP - HUD Reworked 2.0 (link below) to game dir, following the provided instructions in the mod (overwrite files when asked).
4- Install Absolute Nature 4.01 (link below) to a temp folder, with the options of your choice. Delete the following files: "level.ai" and "level.spawn" (from "jupiter", "pripyat" and "zaton" folders) and "all.spawn" (from "spawns" folder), then copy everything else to game dir (overwrite files when asked). Due to a "bug" in Absolute Nature installer, it may not give you an option to install to a different (temp) folder if you have already installed it before, but deleting the listed files from game dir after the installation of Absolute Nature should be ok too.
5- Copy the content of this patch to game dir and overwrite files when asked.
6- Start up the game, adjust all options and there should be a new sound device showing up in the sound settings menu, called "DirectSound". Select that, enable EAX and restart the game.
A- Don't forget that you must modify the "fsgame.ltx" file, found in game dir, in order for any changes of these files to work in-game. Once you open "fsgame.ltx", change the "$game_data$ = false| true|" statement into this one: "$game_data$ = true| true|"
B- To enjoy surround sound, make sure that you have OpenAL, that renders 3D sound and is compatible with S.T.A.L.K.E.R (link below), installed.
