Some games are flawed due to poor programming (see example: Monster Madness) while others just aren't finished when shipped (see example: Monster Madness... AGAIN). Vampire Rain is flawed for a very interesting reason, and that is really, really bad design choices. From a technical standpoint, there's nothing wrong with it. But if you play it, you'll think otherwise.
Now, some people like this game. It tends to be very specific about how beat each of the 20+ levels, and you could say it's rewarding when you figure it out. It's not. I didn't beat a single level on my own, and had to use a youtube guide to beat this. But the frustration has only begun...
I didn't pay attention to the plot here (I didn't actually care) but the abridged version is are there are "Nightwalkers" (super vampires, that thankfully DO NOT SPARKLE) in the city, and you have to find out why there are here and exterminate them. The actually gameplay is Splinter Cell-esque, but done so bad it borders on unplayable.
What Splinter Cell did right was how you can approach your objective. Sure, you can punch a guy in the back of the head and hide his unconscious ass in the shadows, but what if he saw you before you punch him? You could run away and wait for him to stop searching, you could use him as a human shield, or you could just shoot him in the face.
Vampire Rain however... not so much.
Now they are "super vampires," which makes sense that they are hard to kill. But it takes a full assault rifle clip (30 bullets) TO THE FACE to take one down. And they just don't take it while you fire, they CHARGE you like a linebacker. Worst of all is you can't defend yourself, you lose roughly 80% of your health when he hits you once, but this knocks you flat on your ass. So he hits you again, dead. At least if they spot you, it's simple to escape as they just stand there and go "HUH?" Even if you walk away from them IN A STRAIGHT LINE, they won't do anything. But if you get spotted, you're done. Unless...
Later in the game you get better weapons, like a shotgun and one hit kill sniper rifle. There is an odd satisfaction about finally getting to fight back, until the game takes these away and leaves you with the crappy assault rifle and pistol combo. You do get special knives that are one hit kills, but the only problem is THEY BURN OUT (which, to the game's defense, they are UV knifes, so it does make sense), and they ONLY WORK FROM BEHIND. If a bloodthirsty linebacker was charging headfirst at me, and I had a knife in my hand, one of my first reactions would be to stab him in the gut... or whip it at his head.
Now, we've only talked about the enemies, but there are bosses in the game too. You'd think they'd be nigh impossible to defeat, but they are so easy it's embarrassing. The first boss, who looks like a gay biker, carries a shotgun, but would rather chase you around and attempt to put his boot up your ass. The second boss wears purple spandex and laughs like a crack addict. One of the last bosses is clearly a Slayer fan, as he makes it rain blood. Oh, and you shoot him in the gut while he recites some ritual that he always starts over and over... BLAH.
The game is actually fairly long. With around 20+ missions, as well as optional challenges and tutorials. Of course these challenges don't actually give you anything, so unless you are going for achievements (which you must be if you are playing this) there's no reason to do them.
There is even DLC out for this game. I have nothing to say about that.
There is an online component, which is throwaway. 650 of the achievement points come from this though, and two people can get all the online achievements in roughly 70 minutes. Maps are too big, and just in general, nobody cares.
The other 350 points come from the "hard as balls" single player. You get 50 points for beating the game. That's it. You also get 50 for dying 200 times (which strangely was one of the last achievements I got), and 50 for S ranking (a near impossible task, since the game grades you on your ammo usage, death count, AND ITEMS PICKED UP) every level/challenge. Personally, I thought I'd never do this. I still can't believe I did, and to everyone reading this, just don't. Keep your sanity while you can.
2007 must have been a bad year for the Xbox 360. We got the triple threat of Hour of Victory, Monster Madness, and Vampire Rain (And I know I'm probably missing some). The Japanese really liked this one for some reason, (Famitsu gave it a 30/40) but the rest of the world loathed it. They even redid it on the PS3 a year later (much like Monster Madness) and it still sucked. To it's credit, it's playable, but barely.
I should have taken the hint when the guy at the game store told me it blew balls when I bought it for 10 bucks.
