Painkiller and Serious-Sam fans can try this.All others don't go near it.
First one, if you like me you are gonna think that dreamkiller is more mediocre when you sexual life (really bad)
Second, you may actually like it if you'r fan of old-school FPS's.
First of all there's no story line, you just get a crapy slideshow at the beginning and from that point there's no more story.Levels aren't connect with each other, all you get is some record file at the beginning of each level.
Graphics aren't that bad but not good either, the only good thing about graphics is that they are optimized pretty well.Everything else is just plain and boring, except maybe for neat guns and some bosses models.
The gameplay is actually one of the most feature-short i ever saw in my life.You just drop in some room, kill a dozen of monsters while running with super-speed and move to next room again and again till you reach boss, kill him and go to next level to repeat all above again.You have some fancy guns like plazma gun, mini-gun, shot-gun and so on which actually look pretty cool and are different from each other but that's about all good in gameplay.The two powers you got is pretty boring and uninspiring - you can shoot flames from your fingers (they look exactly like in bioshock) and some weird white lines which i don't even know what is. There's also a useless projection of yourself and a more annoying when fun rage mode - you just kill dozen monsters really fast and go to rage mode, your screen goes grey reducing visibility and thats about it.
So as i mentioned above don't buy this game unless you are sure that you'll like running around rooms and killing dozens of monsters with some fancy weapons and no storyline.
