Glad that you've completed the onward phase of the game and returned to Pripyat for the Free-Play phase,
3040Krag (This is the correct course of the gameplay on this mod.) After you've taken the last LV on the NPP roof, you are transferred back to Pripyat. Then it's your luck what kind of a mess that the player finds himself
If you hadn't killed the rooftop RPG guy in Pripyat before, you'll find him there waiting for you when you've returned)
This phase of the game, the Pripyat return is a wide-scale battle fought between many parties, and with the inclusion of all sorts of mutants and creatures. You will see waves of Stalkers, bandits, mercs, Duty & Freedom soldiers, monoliths rushing through the streets towards NPP as the emissions have now been stopped, and entering bloody battles between them. Staying in Pripyat for some time, will bring grand battles for those who like such episodes.
In order to walk around the NPP you should not take the last rooftop LV, but instead you should turn back and explore the grounds; however, you can still get back to NPP as before through the Pripyat-NPP exchange., if you wish so later.
--Yes, if I understand the example that you give correctly, it'd be correct to call those mini-episodes as mini-blowouts, sudden radiation spikes. It is an effect which was to be used for the hit effects of some radiation bullets as well, but those ammo were later removed (may come back later)
-- I can't quite visualize the example about being thrown/dragged through solid objects after being shot (and killed probably), but if you are still alive when that happened, it must be some rare glitches on this specific situation; however, if you mention that this happens after the character is fatally wounded (and the game is over after those scenes) then it's the case that STALKER continues after the game is over, well, in a sort of suspended animation style without the interaction from the player, and in those circumstances, the game engine may throw the body (the player) very high in different directions, which may even go through some solid material; this is the way the engine sometimes works, quite normal.
Well, thanks again for your great praises, I'm very pleased that the mod has left a good playing experience
I'm sure everybody join me in this. Pripyat return episode will bring experiences not least less exciting.
