Anarchy Reigns

Anarchy Reigns (known as Max Anarchy in Japan) is a 2012 multiplayer online beat 'em up game by Platinum Games for the Play Station 3 and the Xbox 360. Given that most of the currently announced playable characters are from MadWorld, or related to it in some way, including it's protagonist, this is possibly a sequel to that game.

Tropes used in Anarchy Reigns include:

Alien Blood, Black Blood: Generally, most player characters bleed dark red blood while mutants seem to bleed either blue or green.
Combos
Combo Breaker: The 360 spin gets you out of a ground combo and sends your enemies flying away at the cost of some of your life (except when someone equips the spin master perk)
Darker and Edgier: At least aesthetically. The game still follows MadWorld's style of having a serious storyline, while everything in-game is delightfully ridiculous.
Fire, Ice, Lightning: The Rin Sisters.
Giant Space Flea From Nowhere: Sometimes mini bosses come out during a fight. The demo show's us a giant robot called Cthulhu and yes you can punch him out.
Ground Pound: As well as using the Strong Attack while descending from the jump, if a character falls from a high-enough distance then they quickly pick up momentum and can cause heavy damage if they manage to land on an enemy.
Guest Fighter: Bayonetta will be this, and is playable if you Pre Order the game from Japan.
Hollywood Cyborg: Nearly every character is this due to replacing one or all of their body parts with weaponized versions.
Impaled with Extreme Prejudice: The signpost from MadWorld returns!
Improvised Weapon: From Signpost and tires to C02 tanks and cars.
It's Raining Men: If someone jumps off of something high enough they will start to catch fire and land on the ground just fine damaging anything or anyone they land on, next to or on the way down.
Kill Sat: The Satellite laser.
Limit Break: Rampage Mode, which makes you invincible and gives you unlimited Killer Weapon usage, as well as upgrade your regular attack combo(s) into Rapid-Fire Fisticuffs which can quickly slaughter the enemy if they don't block and dodge.
Made of Iron: While this would normally be self-explanatory to some degree, one of the videos has shown that the often used way to brutalize mooks in MadWorld, impaling them with a pole, has made it into this game as well. So in other words, you can throw traffic signs at other characters, they firmly lodge themselves through the target's head and all they do is cause a minor amount of damage and dizzy them.
Made of Plasticine: On the other hand, the generic mutants are incapable of dying without being cut in half horizonally or vertically or having their upper torsos explode from the force of several weak punches.
Power Trio: Some trailers show Leo, Sasha, and Nikolai working together.
Rated "M" for Manly
Pummel Duel: If you're in Rampage Mode and attack someone who's also in Rampage Mode, you'll enter one of these. If you don't mash a specified face button faster than your opponent, you're likely to get killed instantly when it ends.
The Rival: Jack and Leo.
Shout-Out: Plenty, not just to many of the other games Platinum Games has made, but to a bunch of other games as well;
- One of the events that can occur during a match(or at least on the stage featured in the Demo's Team Deathmatch) is an orbital Microwave energy blast (if you don't find cover, it will instant-kill you without exception).
Sequel Reset / Spiritual Successor: The game is apparently not a straight-up sequel to MadWorld, though it contains a few of the characters. Jack is still with the Chasers, and is actually recruiting for them. Leo, Rin Rin and the Black Baron are still alive, which is not surprising at all in the latter's case, and Mathilda returns too.
- Actually, the Leo Victorian in Anarchy Reigns is a completely different character. He just happens to have the same first name of Leo Formont from the first game.
Sniper Rifle: One of the items the player can pick up. Yes, sniping enemies while they're busy fighting each other is a valid strategy.
Testosterone Poisoning: In a development blog, the director referred to the "macho percentage" of the average male in game as 300%. Including the women, the average character is only 200% macho.
Too Soon: Only time will tell if the Tsunami stage will stay due to the wake of the Fukushima disaster in Japan.
Wilhelm Scream: Seems to be a Running Gag from the looks of some trailers.
Wrestler in All of Us: Everyone can do throws, from a standard power bomb to some more complex moves: each character has at least 3 basic throws depending on if they're done from front, behind or on grounded enemies and some Killer Weapon attacks work like throws when they connect.
