The Painkiller: Redemption experience can be more or less summarized like this:

You enter a cramped area filled with a dozen or so enemies. You kill them. A dozen or so more spawn. You kill them. A dozen or so more spawn. You kill them. A dozen or so more spawn. You kill them. You start to notice how obtrusively restrictive the level design is on your movement. You start to feel claustrophobic, but instead of instilling fear it instills disgruntlement. I thought this was supposed to be a Painkiller game, you think to yourself. A dozen or so more spawn with a few tougher enemies. You kill them and stand next to the door to the next shooting cell, because surely that had to be the last wave of enemies.

NOPE ♥♥♥♥ YOU 3 MORE WAVES.

You alt-f4 out of the game, delete it from your library, and stare out your bedroom window, reminiscing about the $5 you just blew on this steaming pile of refuse.

This game sucks. It is a fanmade mod for a Painkiller and it is a bad mod without any interesting idea inside. Previous fanmade Painkiller mod, Resurrection, had a lot of technical flaws and was barely playable, but it had some interesting ideas and sometimes it had nice design. But this one just sucks, developers gave up on their own ideas from Resurrection instead of developing them further - and this was a bad idea. Bad game.

But if you really like to tear thounsands of monsters in one little gray room for hours - take it!

its crap

Be warned this game is a fanmade product meant only for real hardcore FPSers! As I’m not one of those i had hard time to progress.
This game is the absolute opposite of the cursed Painkiller:Resurrection. Again only a few levels (6+2bonus? the boss is on the 6th) but because every of them features around a thousand enemies compressed into small areas you won’t miss action in here. Practically the levels consist of a series of survival rooms and they are hard as hell. I wasn’t able to make it through the first level on normal, had to lower the difficulty into the very lowest (no cards or souls), even if I knew i won’t see the ending not even half of it, maybe a black screen featuring a short text „You are a miserably weak player :P”. Actually i saw the ending but it’s not a big thing, this game is not about story. Furthermore I did not regret the difficulty decrease after i saw the levels after. The second level is a pain (in some dark warm smelly place), shooting enemies spawn 2-3 at a time, and every of them start with a shot, giving you no chance to beat them before they hurt you. On later levels the rooms become smaller with the same amount of enemies, sometimes i really wondered how those could be beaten normally as the real usable crowdcontrol weapons, the stakegun-grenade, the xbow-bouncies or the rocket launcher cannot be used in such claustrophobic places without seriously hurting yourself.
No new content at all, but it features most weapons and enemies from all its ancestor Painkillers. The levels seems to me as multiplayer levels recycled into a single player nightmare.
When i started I had fear what I will find after the awfull Resurrection but the game started good. Lower your expectations and forget about exploration and other nerdy things in this one, it’s mindless pure action! Think of this one as the action essence of the original game.
Later on i found it must be impossible to carry on with higher difficulties and it started to bore and annoy me. At the very end i again started to enjoy the game but i’m sure you need a special mood to find delight in this continous massacre.

4/10 - Pure extreme hard, room survival FPS action. Fun when depressed.

(Sorry for my English!)

First of let me say I liked the painkiller games,but this one is just too bad.
The plot of this game that you enter a room and kill hundreds of demons just to enter another room and kill more demons.
The game itself is great since it is violent and brutal but the game doesn't offer much else.
Sure you can still see a lot of blood and body parts but that's about it.
I could still reccomend this to a fan of the painkiller series.
