You don't just dare to play this game, you Double Dragon dare.
Double Dragon Neon is a 2012 Double Dragon spinoff/parody developed by Way Forward and published by Majesco. In the style of a 2D Beat 'em Up, it strives to be both a parody and homage of its predecessors. It also offers both single-player and local co-op (refered to as "Bro-op").The plot is simple: Billy and Jimmy Lee go through a series of levels to save their girlfriend, Marian, from the big bad, Skullmageddon. What it lacks in plot, it more than makes up for in in-jokes, challenging gameplay, and awesome music.It is available on Xbox Live Arcade for 800 MSP, and on Playstation Network for $10USD (formerly free for PSN+ members), with a release on Steam following in 2014.
Double Dragon Neon contains examples of:
'80s Hair: Oh so much, in pure Double Dragon style.
Pretty much the only character that doesn't have this is "Your Worst Nightmare Skullmageddon" and "Bone and Metal Giga Skullmageddon. Also "Most-Refined Ichisumi" and "Gyroscopic Jerk Hoverbizzle", a robot.
Crazy-Prepared: Spoofed in the Giant Tank fight, where Billy claims they actually trained for this with an anti-tank technique. Subverted in the Marian II boss fight when Billy points out to Jimmy that they never trained for killer plants with animal heads.
Creator Cameo: A strange example: hitting the punching bag in the beginning of the 7th level exactly 87 times teleports you to another part of the stage, except now everyone's heads are replaced with the series creator Yoshihisa Kishimoto's: completing the area nets you an achievement and sends you back to the beginning of the stage.
Critical Existence Failure: The Lee brothers and enemies alike will continue fighting no matter how many boots, fists, floors, and weapons they've taken to the face.
Deus ex Machina: Marian just so happens to have gained the power to send the Lee brothers after Skullmageddon after he escapes for the second time. Plus, the portal turns them into super powerful Ro-Bros that can take down any mook with a single punch.
Do Not Drop Your Weapon: Bao Boshi's magic staff, and Skullmageddon's sword seem to be the only two enemy weapons you can't pick up.
Enemy Subtitles: Present for every enemy's introduction, most with Added Alliterative Appeal: "Cartwheeling Cannon Fodder Williams", "Expensive Experiment Giant Tank", "Your Worst Nightmare Skullmageddon", etc.
Genius Bruiser: Parodied with Abobo, some of the things he says if he kills you are "Abobo need to study for tests", "Abobo have degree in physics", and "Abobo ready to pass the bar". The shopkeeper even mentions that he's working on his master's thesis.
Gretzky Has the Ball: Billy and Jimmy occasionally shout things like "Touchdown!" or "Hole in One!" when smacking enemies around with the baseball bat.
Guide Dang It: Many of the secrets are ridiculously obscure (punch a punching bag a 87 times and no more than that, crouch at a specific spot 7 times), although most of them are hinted at if not flat out spelled by the shopkeepers if you talk to them enough times.
Hammerspace: Mostly averted: weapons mooks come with are shown on their hip (in the case of Linda and whips). Billy and Jimmy cannot store away weapons and items at all.
Harder Than Hard / Numerical Hard: two difficulty levels above the the default Normal called Dragon and Double Dragon, both of them greatly increasing all enemies' stats.
The hair pick does a whopping 1 damage when it hits someone, and then notably sticks to their hair. Using it on every enemy will get you an achievement/trophy. When used on Skullmageddon (which will net you another achievement), it pins his hat to his head (which he lampshades when he tries to remove it).
The key, which is used to open treasure chests, gives you an achievement if you manage to defeat someone despite its pitiful damage and ridiculously slow animation that involves Billy or Jimmy jabbing it forward, trying to unlock thin air and then spreading their arms and going "What the!".
Just Plane Wrong: well, Just Helicopter Wrong: the Killacopter performs maneuvers that are flat-out impossible, like trying to inflict Helicopter Blender on Billy & Jimmy by flying upside-down about six inches off the ground. Underscores just how much the game runs on Rule of Cool.
At least in the case of flying upside down this is actually a case of Reality Is Unrealistic. 6 channel CCPM model helicopters do this and even crazier things.  There's no reason full a size helicopter couldn't do the same if it had a high enough power to weight ratio and a pilot crazy enough to attempt it.
Kick Them While They Are Down: You can punch downed enemies (regardless of whether you knocked them down yourself, they fall down from the sky on fire or are thrown off their malfunctioning hoverbike) for large amounts of damage, although with some enemies it often results in you getting hit by their wakeup attack if you don't do it as quickly as possible.
Rake Take: Several stages have large boards with an X on one end: stepping on the X causes the other end to fly up, catapulting any enemies standing on it high into the air. They're often positioned so that you can either juggle the enemies back and forth between 2 such boards before they have a chance to get up or quickly fling annoying enemies into a pit.
Rewarding Vandalism: From trash cans to mailboxes to light poles to sacred monuments to gravestones, everything seems to have soda, batteries, or cash in them. Lampshaded when you destroy said monuments when Billy shouts "Sacrilegious!" in the same excited way he'd shout "Awesome!"
Running Gag: In the battles against Skullmaggeddon, attacking him will yield shouts of, "Ow, my X!", where X is the name of a bone (tibia, ulna, phalange, etc). Since he's, you know, a skeleton and has no Useless Spleen to be punched in.
The final dungeon of EarthBound has many similarities to the final stage. Namely that The main characters are robotized and enter one way time portals to chase the final boss.
The "Continue?" screen is a shout-out to Ninja Gaiden and Final Fight's similar continue screens which show your hero in mortal peril (unless you insert more quarters/press start!)
The "Key attack" mentioned above is a reference to Castlevania: Rondo of Blood. In fact, the game oddly contains so many references to Konami games instead of its own parent company one would think the developers were making a sequel to Violent Storm.
The "Mistranslated Mutants" Bimmy and Jammy; the former name is a nod to the typo in the NES version of III where Billy is called "Bimmy".
The final area just before the final fight with Skullmageddon also has an invisible ladder that leads to an area with 3 treasure chests and extra lives, much like the invisible platform that rains down powerups right before Dracula in Super Castlevania IV.
The 4th level boss, Mecha Biker, is basically Mega Man in every sense of the way: he's referred to as a "Super Combat Bot" (referencing the animated series' theme song), rides around on a red jetbike much like Rush, shoots 3-shot bursts and charge shots, slides around and even explodes like Mega Man when defeated. His boss arena also has a pair of rising gates leading up to it with a short corridor in between them, and yes, you can jump through the gates and have Billy freeze in midair during screen transition. Finally, the platform the battle takes place on resembles the Mega Man boss introduction screens in both overall color and the borders on top and bottom of it.
Each type of mixtape you can get includes a short version of the song in question, most of which have fitting music genres.
The boss Skullmageddon appears to be a homage to Super Shredder, the final boss of Teenage Mutant Ninja Turtles: Turtles in Time. This is up to and including his boss theme having a lot of snare drums and slap bass in it similar to the sound Roland synthesizers produced when used in Konami's soundtracks, teleporting when approached, and flashing colors when near death.
The "go" indicator arrow familiar from other beat'em-ups is basically a modified Power Glove.
When you hit an enemy with a baseball bat, the Lees may yell "Boink!!"
The fake band Mango Tango, performers of "Neon Jungle", may be a reference to the 80's band Bananarama, as the song resembles that band's style.
Small Annoying Creature: Fuzzface, who only appears if you crouch in a specific spot repeatedly. The bad news: It's a creepy oversized bee thing with googly eyes that constantly stare at the screen, an annoying voice and once you make it appear, it keeps following you around until you beat the game. The good news: it periodically drops lots of life and energy recovery items which is extremely useful on higher difficulty levels and you can hit it by "accident", which makes it shout out in pain or say that it "knows you didn't mean to do that".
Space Does Not Work That Way: Played for laughs on the Airlock level, which requires the Lee brothers to go outside the pressurized parts of the spaceship. They panic when they realize there's no air, then take a deep breath and (presumably) hold it for the duration. The shopkeeper points out that this is a really bad idea if you talk to him enough.
Whip It Good: Linda's weapon of choice. Can be used by the Lee brothers.
World of Ham: The silliness of the 80's is first embraced, than multiplied exponentially.
World of Pun: The game thrives on this: when Skullmageddon isn't making enough skeleton puns to make Brook think he's being excessive, the Lees and the normal enemies also use them liberally, mostly when using various weapons and during cutscenes for the former and during their entrance and if they manage to deliver a killing blow for the latter.
Would Hit a Girl: Pretty much every guy in the game, from the opening intro where Williams sucker punches Marian in the gut and carries her off, to Billy and Jimmy beating the crap out of the whip-wielding Lindas.
You Bastard: Upon defeating Skullmageddon in the final battle, he congratulates the player in crushing his dreams in having a girl of his own.
Your Princess Is in Another Castle: At the end of the second stage, you find Marian chained to Skullmageddon's throne, but he has her taken away before fighting you, then jumps out the window afterwards. After his spaceship crashes back to Earth, the pursuit continues.
