Here is the text from those screenshots translated:
A significant part of Pripiat will be recreated with 100% accuracy. Except, this time it will be not the central, but the Eastern area — the developers want to show us the city from a new perspective. There will also be the "Jupiter" factory and the buried village Kopachi.
2. Even smarter
GSC yet again promises to get the A-life simulation system up to snuff. Although, there will no longer be faction wars — that has not worked out.
"Call of Pripiat is a real sequel. After Strelok destroys "C-Consciousness" in the original game (the developers ignore the alternative endings), a government expedition has set out into the Zone. However, something went wrong, and the expedition vanished without a trace. In order to investigate the causes of this catastrophe, a Ukrainian security service agent is sent. Whom we, obviously, will have to play as.
Quests in the previous games looked like a product of a random number generator. This time we will get about 70 optional quests made by hand. So, this time there will be no "go to the woods and kill five boars".
5. Small and hungry
"Call of Pripiat" will have two new monsters. Burer is a dwarf with telepathic abilities, which could be found even in the original game's archives, but this time implemented properly The second addition is the Chimera, familiar to the readers of Stalker books.
Blowouts will have a larger effect on the game world. If previously they entailed only a reddened screen and death, should we not make it to a hideout, this time they will radically change positions of anomalies and artefacts.
