First off, let me preface this review by saying that this game is rather short and if you wanna play it on a computer with a dual core processor you are ♥♥♥♥ out of luck. However, if you can run this game, it is well worth your time and money despite these two problems.
Be sure to see the guide as well on getting this game to run up to snuff, unless you're one of those people who think a game is enhanced by a subpar framerate.http://steamcommunity.com/sharedfiles/filedetails/?id=262696032
tl;dr? Get this game if you're into the hack and slash genre even slightly, enjoy a moderate amount of difficulty, or appreciate a unique visual style in a video game. (Seriously, some of the frames in some of the cutscenes in this game are wallpaper worthy.)
Killer is Dead is one of the most unique games I have ever played. Perhaps not mechanically; after all, this is at it's core a hack and slash game and it does have many tropes of the genre such as a grading system and guarding/dodging mechanics. As for the mechanics themselves, they're actually very solid if a bit overly simplistic to those who are used to DMC levels of depth. However, everything about it otherwise, from it's beautiful visual style that's reminiscent of 70's esque color pallettes, character, and outdoor design gives this game loads of personality and unique identity among others in the genre. I will forever remember this game because of how unique it is.
Oh, and the soundtrack is a beautiful blend of electronic ambient and classical music. Often very dreamlike, much like the game itself.
This game is not without it's problems though. Sometimes, the camera may not zoom out enough to give you vital information on the next enemy telegraph, leading to mild frustration at times. You will hate the gigolo missions not because they're bad (They lack a lot of depth, though.) but because the people you date will bother you in the middle of a mission to remind you that there are, in fact, gigolo missions and the girls want to see you before their mission gets locked off until you complete a few other missions. A minor inconvenience, of course. But I am of the personal belief that side missions should not detract at all from a main campaign and should be able to be played at your own leisure. I assure you, this is said in the interest of informing about an unsatisfactory gameplay mechanic, not in regard of a controversial subject at the time of this review that I don't want to touch with a 1,000,000 foot pole because I honestly, really, could not give less of a ♥♥♥♥ if I tried, since said subject does not detract from a game for me at all. I only offhandedly mention it because some people do care and they should know it is in the game.
There isn't a lot of enemy variety in this game either.
However, this game is well worth your time and money, and I would even go as far as to say that it is a must own if you want to experience a game that is unlike most you've played. Expect challenge.
