You know how some people like old Godzilla movies, even though they have the obvious rubber monster suits? Somehow the cheesiness makes it endearing to them kind of thing. This game is sort of like that, but as a silent movie. I'll get to that later. I gotta admit it, this game is one of my guilty pleasures. I know, I should know better. PeaceKeepers(PK for short) has got a lot of flaws, but just the fact its so out there, I still find myself succumbing to its siren song of strangeness.

Let me just break the story down, as now changed by localization. Your fighter(with or without co-op friends) are hurt personally by a big corporation, in this version its called Deutchland Moldavia, or DM. They each have a cause to lay into the CEO. The CEO is Iago, a short guy who is named from the play Othello and also talks like Shakespeare. But DM is like Umbrella company in Resident Evil, that is, it makes creepy mutants all day to find the perfect race. So you can see your heroes are going to run into trouble.
Now if this was Final Fight, you'd be a big, beefy dude or or a karate expert with big awesome graphics and larger than life bosses.
If this was Streets of Rage, you'd have a kicking soundtrack and be police officers with super crime-busting kicks and punches.
But this is Peace Keepers, and your heroes are.. Flynn, a rather average looking guy! Al, another average looking guy! Echo, a woman wearing short shorts and a ballcap! Prokop, A big hulk hogan colored guy that moves like frankenstein and is totally not a cop!But wait, there are hidden characters! A gold robot that doesn't actually have many cool moves, and a regular-joe guy wearing a ... leather jacket. Yes sir, these are your Peace Keepers!
So your heroes have little in common with each other, other than their hatred of DM's shenanigans. There is no explanation how they all teamed up to even fight DM, and in co-op they seem out of place. That's normally bad, but check this out, the enemies and stages are hilariously  totally out of place too! Lets get into the metrics of the score, and find out why I think PK is so bad it somehow ends up a little tongue-in-cheek good.

Graphics: 4
The graphics for SNES standards are pretty meh. The backgrounds are somewhat detailed, if not particularly stand-out, and there are many different locations for stages. But the enemy designs are not varied and are pretty lazy overall, some mini-bosses are just palette swaps of regular enemies. The animations are not great in this game. The explosive effects for fire attacks are fairly on target with the system, however.
There are some nicely graphics in the special attacks that liven up the rather pedestrian art of the backgrounds, Flynn's lightning and Al's Tornado especially. There are also some questionable art, like the badly drawn mines on the first stage. That's something I would expect in a NES game, really.
I have a slight beef with the strange sizing of the characters vs. two or three bosses. How can I put this? Ever play Wrath of the Black Manta? No? Ok, lets go back to Godzilla. Picture a tank fighting him. Your first boss is a human guy who is like, 4 times your size. Monster height and their arm is as big as your body. But you're thinking this is a mutant enemy, right? But get this, hes not a mutant, just a regular guy apparently, like you. HA! The army guy, Al, even knows the boss, and doesn't seem to think this grossly abnormal growth is an issue. What the heck? Why isn't the whole game filled with people like this, and make the game more impressive? Dunno.

Sound: 2
Hold on, the game deserves a low score. For some reason, the localization team cut the soundtrack. I have no idea why this made it to final production.  You do hear some background noise, and the same dull moans from enemies dying, a crude thud sound when people hit the ground, but nothing good. The localization brutalized this aspect, and its not just one stage. You will play many, many stages, all with soft, ambient sound. Its really, really terrible honestly, as none of the enemies sound different, and your characters have different voices but who wants to hear their shouts and oddly accented words all day(such as "Fi-yah!")?

Addictiveness: 7
Your mileage may vary, but despite PK being nothing special and having mutable sound, I will still play this. The obvious replay is with the hidden characters, as in game you can only get one or the other. But the whole game is designed around yes/no choices. The game plays up its odd tale, so seeing the many character's small dialog to a stage can add insight.  And besides character selection you get other options; two main ones, choosing the next levels without a stage select screen, and the importance of your selected character to the current stage.

Take the first stage for a great example of both.
One- You fight a big boss guy with a knife, or a weird green jumpy boss guy who looks to be turning into a cyborg. You don't fight both. You go up you will fight one, to the right, you fight another. And after beating them, each will lead you to a different 2nd stage.  The game moves forward, so if you want to see the 2nd stage you missed, you have to play again.
The second advantage to the addictiveness is related to the characters and their in game story. Say you take Echo. She will tell one boss she just wants by and then when he threatens her, she will dismiss him before starting the fight. Big deal. But if you take Al, the army guy, he actually knows both of these men who are first level bosses. He will be quite disturbed at what's happened to them, as this turns out to be some of his squad. Its like a weird soap opera! Right there you get some stages that seem a fit for certain characters, but you don't have to play that way.

Story: 6
PK's story may sound crazy(Localization again?), and some of the bosses are out there, but this game keeps the narrative and connects the stages best it can. Sailed on a boat? Disembark at a remote island. Your building got blown up at the end? Now you're in an underground sewer next stage.
I've mentioned how the player characters can play to a stage, and having co-op can add to this too. Both Echo and Flynn share comments on many of the same stages.
One thing I wish it did better was fill in some details. Like DM. They sound german, but yet employ ninjas and silly dressed pirates?
And the choice of year was bad, it says this is 2015. Yikes. Should've gone with the 20XX route.
Also your characters could have had a bio that could come up pre-game demo mode, that would have made us care more about them. Its fine if you have characters that pick up bits of the story mid-stage, but if you don't care about that, the game just goes back to being another mediocre puncher.

Depth: 7
This game has up to 6 fighters to choose until the end of the game, each with a host of moves, many with a 'hidden' regular move, a special move that drains your life, and an 'angry' mode that makes your throws more aggressive. Not bad, but other games can do that.
I do like how the characters feel unique in their play-style, and throws have different strategies. Some examples:

Flynn has the fastest throws, but often thats because he just suplexes them right next to where he is. He can easily finish and find a new target.

Al "Sarge" walks a bit slower, but his slams often end up hurting surrounding enemies, knocking them down too. He also gets a projectile weapon that comes in very handy once you know how to use it.

Prokop has the most control in grapples, but can't run at all. He can pick an enemy up and literally walk with them in a chokehold. Take them to the lip of a bottomless pit and throw them right off to their doom.

The choice of stage is what really sets this game apart. Many options on where to go, and sometimes you end up bypassing hidden characters entirely.  Of course each person has their own ending too.
That being said, the combat can be quite repetitive and I'd knock it down a point. Enemy AI is not great. They are smart enough to hop over obstacles and some can counter-grab, but nearly all are a sucker for running or leaping attacks, making it spam-worthy.

Difficulty: 5
You get 12 continues and have to share them in co-op. Once you learn the enemy types and learn a hero's moves well, you shouldn't have too much trouble beating it. But there are some encounters with bosses that might ruin your day, so its not a sure bet. Some characters seem slightly weaker overall than others, and might be to add more challenge.  If you have a stage or boss that gives you trouble, you have the ability to choose different stage paths and avoid them altogether.  

Overall: 6.2
This game just edges out the 5 zone with its off-the-wall story and great stage variety. Total lack of music is a huge hit to its score, as is the lack of enemies and AI. But while its a mixed up message, I think this game meant well. So ask yourself, do you like metaphorical Godzilla movies enough to try this crazy game out?
