They say that good old-school FPS make a good top-down shooters when viewed from above. All as you have to avoid projectiles while also managing a horde, they don't lose much in such trasnaction.
The article that where I read such thing was demonstarting it on Doom. By opening auto-map and showing how you avoid projectiles. That would make quite a nice arcade shooter.
Painkiller on other hand, as it turns out, has more common roots with zombie themed one. Projectiles are rare and you mostly have to manage crowds, running away in circles.
Anyway, this DLC turns Painkiller into twin-stick top-down shooter. Well, keyboard+mouse one. And it's actually a pretty good one, not just cash-grab.
You kill more enemies than you would do it in main game. But at least main hero feels powered up. Shotgun sure is. You don't even have to worry about enemies with shields, shields are ignored there.
I wasn't exactly sure that it would be good. First level didn't start exciting, as it was simple corridor where you kill everything by shooting into one direction. Thankfully, it would become actually challenging later on. Not only that, but it had a surpringly great pacing. It mixes action with bosses, puzzles and traps. Yes, it actually features small puzzles to break things up, something what main game perhaps could use. Jolly! And they didn't bring hitscan enemies either, clearly sane.
There are flaws though. Not major ones though. First, camera changes height and angle dynamically, trying to show what it thinks player want to see. It isn't always succesful, sometimes it's position in such way that you will barely see anything in direction that you make your character walk to. Then level 4 has a difficulty spike at the last room, where you are facing the boss. Tough enemies are overwhelming there. And then, strangely, there was no music at the last part of level 5, it just went away.
Levels themselves also look nicely. Interestingly, it has 2 maps that come from Recurring Evil! I have no idea, maybe somebody in development team helped with that expansion pack before. But hey, those levels actually were nice, it's just dragged gameplay of that game that was ruining everything. It playes better here for sure.
Anyway, really nice original DLC.
And uh, there is a new Tarot Card that "recovers health after 10 seconds after getting damaged". Or something.
