coming from the old xbox version of the game I can only say this one is a great addiction to my game collection, but it seriously needs a patch to fix at least the following problems:
-blood doesn't show on floors and walls when you hit enemies
-bullet holes and smokes sometimes disappear too quickly or don't appear at all
-in resurrection of evil, after you use the artifact, particle effects often disappear magically

so guys move on, work a little bit and give us a patch as soon as possible

thanks
