I tested it in XP 32bit...
in WR KR: doesn't work
in WR JP: Hammer(90~120 days), MICRO UZI(90~120 days), SIG550(90~120 days), AN94(90~120 days), HK416(90~120 days), AKS74U(90~120 days),CX4STORM(90~120 days) and M40A1(90~120 days)
MP5K_G(3 days), UMP45(3 days) and FAMAS(6 days). I bought all these weapons only with about 3500 dinars in WR JP
all most every weapon scripts are not working in WR KR. some are working only in Zombie mode(WR KR), though.
