I prefer to play Call of Misery but you only need the above link to play.

Call of Chernobyl is a huge sandbox mod that compiles all 3 games into one giant game. It can be installed directly over Call of Pripyat, or there are ways to download and install it completely separate and stand alone.

(If you want to start with slightly better stuff like I did for this campaign, modify the faction_loadouts.ltx file. You can do this with basic notepad or similar program. It is located in the Call of Misery/Chernobyl Directory under gamedata/configs/plugins)

(My setup for my loadout only added 10,000 RU and removed the worn weapon and replaced it with a newer one:

[dolg]:shared
money = 14000
dolg_novice_outfit
wpn_ak74u
ammo_5.45x39_fmj = 4
medkit_army
cigarettes

The rest is all standard.)

Choose Duty as your faction.

Choose image Dolg 3 for your portrait.

Enter the name Koldan for your name.

(THE CHARACTER IS INTENDED TO BE AN ASSAULT CHARACTER SO USE ASSAULT RIFLES, HEAVY WEAPONS, AND WEAR HEAVY ARMOR, YOU DON'T HAVE TO DO THIS)

(YOU DON'T HAVE TO PLAY AS DUTY, THAT IS JUST THE FACTION I CHOSE TO WRITE THE STORY FOR SINCE I HAVE NEVER PLAYED OR INTERACTED MUCH WITH DUTY BEFORE)

Intro:

So this is just something I made because I'm a hardcore STALKER fan. It doesn't actually change anything in game, it's just an imaginative campaign but I thought the story was plausible for the game series. This is something more to do than just the sandbox type quests and since the main quest is always the same, this is just an idea I came up with to make it more fascinating. It is similar to STALKER Call of Pripyat in terms of character design but other than that, I think it's an interesting idea.

Character Bio:

Koldan (name that means sting in Russian) was a Spetsnaz assault operative for several years before coming to the zone. He was sent in to maintain order and as a hunter to track down and eliminate troublesome stalkers who threatened the zones security. When the Monolith reactivared the Brain Scorcher and the Wish Granter became operational again, he was assigned on Operation Relapse.

Operation Relapse:

Operation Relapse is a secret covert operation created in an effort to disable and destroy the Brain Scorcher once and for all.

Objectives:

-Gain Dutys Trust (Maintain a reputation of at least good)
-Maintain order within the zone (Reach Master Rank)
-Remain Low Profile (Do not engage friendly or neutral stalkers)
-Do not engage Military stalkers (You are part of the military)
-Eliminate any stalkers who threaten the zones security
-Disable and destroy the Wish Granter
-Disable and destroy the Brain Scorcher
