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.
