Good artifacts file

Install - Just place the gamedata folder in the main Stalker directory.
"C:\Program Files\THQ\S.T.A.L.K.E.R. - Shadow of Chernobyl\"

Also Make sure your fsgame.ltx file in stalker directory reads this :> $game_data$ = true| true| $fs_root$| gamedata\

spring artifact is the best.
