S.T.A.L.K.E.R. OBLIVION LOST by Kanyhalos 1.3
What's this?
This mod wants to get closer to the old Oblivion Lost, and give the best performance what is possible, with using the 3 best mod features:
Total Freeplay, Modified A-Life, and Reality Enhancement.
It is recommended to play in HELL difficulty!
This mod works properly only with 1.0004 or 1.0005 or 1.0006 patch! The default is 1.0005!
FEATURES:
FREEPLAY
- New level changers (Stancia2 to Control Room, Control Room to Sarcophagus, Sarcophagus to Stancia1, Stancia1 to Pripyat, Cordon'to Dark Valley and a new Radar to Bunker)
- Removed the scripted blowout from Stancia1 and the dead zone from Stancia2, so you can explorate the whole Power Plant
- The last portal teleports the actor to the court, so the game is open-ended
A-LIFE
- Now almost everything can be happened, there's a chance to meet any NPC's on other levels
- Sometimes the army raids, sometimes not, this is totally random, too
- The mutants are making their ways through pass the Zone in big hordes
- The mutants are entering places what they aren't entered before, so there's an increased chance to meet them in human-being places
REALISM
- All weapons are strongers and well-balanced
- Almost to all weapons be able to attach addons
- Added realistic sounds to the weapons, rounds, ammos, materials, environment
- NPC's are bleeding, if they are hurted then fall down to the ground, and if they don't receive any medkits about a minute, then they die
- Bandages and foods don't heal the actor
- The average bleeding don't stop by itself, only the minor
- Added realistic head-bobbing to the actor when he is heavily wounded
- Well-balanced armor degradation
- The crosshair is reduced to a dot
- Reduced HUD and removed NPC counter
STEALTH
- The NPC's can't notice the actor during night if his flashlight is turned off
- If the actor turns on the flashlight, then his enemies spot him immediatelly
- Reduced the sound volume of the Knife, now it's a dangerous and invisible weapon during night, presumably the NPC's won't notice the actor if he is smart enough
WEATHER
- There are 24 hours cycle weathers in all levels
- The night is dark and scary
- Restored the Sun and the Moon
- Atmospheric sky textures
- You can hear the sound of thunders in indoor levels, too, of course with less loud, and the lamps are flickering a bit during intensive storms
BLOWOUT
- The blowout is totally random, you never know that when it will start
- The blowout spawns mutants and artifacts in random places
- The NPC's are falling down when the blowout starts, and they stunned to the ground when it explodes, also the actor is slowered and has got some minor effectors
- The blowout is dark at night and shiny at daylight
- If the weather is rainy, then the blowout increases the intensity of the rain, the thunders and the wind
MUTANTS
- Added all cutout mutants (Dwarf, Chimera, Cat, Zombie, Izlom, Rodent)
- They have got so many different types of skins
- Added the Psy Dog as a new mutant (with attack effector)

VEHICLES
- Added all drivable vehicles (Niva, Zaz, Kamaz, Tractor, UAZ, BTR, Moskvich)
- The vehicles aren't floating
- Well-balanced driving properties
- Added realistic engine and gear sounds to the UAZ
ARTIFACT ACTIVATION
- This is a method of transforming the artifacts created by an anomaly back to the anomaly they were originally created in, so you can set traps for your enemies by using your arifacts as a weapon
- Each artifacts have got different HUDs
