As I stated in my previous Painkiller's coverage of beta version and demo, Painkiller reminds me of the good Doom, Quake, Blood days in terms of playability and atmosphere. Yeah, It feels very old school just like Doom, Quake, Blood mixed with Serious Sam-like "intense" gameplay - you will be constantly outnumbered, fighting against seemingly insurmountable odds - if it moves, shoot it and if it still moves stake it to a wall! :) There are no puzzles, no adventure elements, so if you are looking for an in-depth storyline will have to look somewhere else. Also, I've noticed that many people compare this game with Serious Sam. Well, I don't think this game comes too much close to Serious Sam. The fast reactions and accuracy and the seemingly endless number of enemies coming at you, these are the things I remember already from the classic old-school shooters. Rock stable gory horror action, what more is there really to whish for?
