Q: What will be the biggest difference between S.T.A.L.K.E.R. 2 and the previous games, if any?
A: In brief, S.T.A.L.K.E.R. 2 will offer new story, new set characters (with some good old ones) and, of course, the new engine powering it.
Q: Will there be more of a survival element to STALKER 2?
Q:What features have been removed/compromised in the PC version due to the multiplatform release?
A:Since we develop primarily on PC, you won't see any compromises in the PC version. The key difference between the PC and console versions will be the beauty of graphics (meaning PC will offer more of visual effects).
Q:Will there be any new kinds of interaction with NPCs?
A: How do you mean? It's difficult to answer this one.
Q:Will Sidorovich be in S.T.A.L.K.E.R. 2?
A:I will refrain from answering this one for now.
Q:Will the faction wars return?
Q:Will the interface (inventory, map, etc) on the pc version suffer (like other games have) by trying to cater for console systems?
A: No, whatsoever.
Q:Will there be any new mutants?
Q:How many weapons will be in Stalker 2?
A:It's difficult to give the quantitative figure at this point.
Q:Which part of the zone will it take place? Or is it the zone at all?
A:We'll be locating the game in the triangle of CNPP, the cities of Chernobyl and Chernobyl 2 (where the huge antenna is located).
Q:Is Zone going to be a large single ?
A:Let's postpone this question for now.
Q:Will it support DX11?
Q:Will we see more X-Labs and secret underground complexes?
Q:Will GSC expand on the import-a-weapon feature introduced with Nimble, and allow players access to more varied and custom weapons from outside the Zone by importing them through specialist contacts?
A:We have some interesting new ideas on this matter.
Q:Will artifacts be something we can go out and transmute through Anomalies?
A:No. However, the area of artifact application will expand.
tl;dr: Evasion, evasion, postpone, add new shit, no PC/Console compromises.
