---QUOTATION--- If I install the xKoveKx patch, mutants and soldiers don't attack me, and if I kill a soldier or a mutant, everybody becames enemy (stalkers too). How can I fix it? ---END QUOTATION---

---QUOTATION--- Hello, Are there map textures for the pda available anywhere for the two maps mentioned above, cheer's ---END QUOTATION---
For old Dark Valley and Bar+Rostok? Not that I know of. You can see them on the old global map texture, but they were replaced before high-res textures for individual maps were added to the game.
For the Rostok factory map, you might be able to use the texture for the final game's multiplayer version.
