Every single word is not needed for this masterpiece.
Remakes aren't usually at the level of original ones; however THIS TIME the Polish studio overcame the original on EVERYWHERE in this game. The only reason I do NOT vote it 5 stars it's due to the problem (in consider it a problem) of modern FPS: it's too driven and there are zones where you fight and safe zones, while in the original one (and 90s FPS usually) there weren't "safe zones" and basically the environment actually was you real enemy. Anyway, great story.
When I was a child I wa actually unable to understand this game (I mean, how to play), but now with nowaday awareness I can finally play and understand it. Thanks GOG!
