Hank's idle animation, along with him holding a red microphone and a combat knife, is directly taken from the sprite shown off for him in the original trailer for Friday Night Funkin'.
The song's title comes from Madness Combat: Accelerant, a Madness Combat fangame created by Tom Fulp.
The other two protagonists of Madness Combat, Sanford and Deimos, appear on cliffs to the left and right of the fight to shoot down the numerous threats that try to interrupt.
Halfway into the song, none other than Tricky crashes in on top of the speakers to sing a few verses, bringing with him his voice and mechanics from The Tricky Mod.
After Hank shoots Tricky off of the speakers, grunts and Mag Agents will pop up from behind the speakers periodically, but are almost instantly shot down by Sanford and Deimos. In Fucked difficulty, Tricky instead rises back up in his Hellclown form to watch the battle, tanking all of the bullets with ease.
Soon after she's knocked off of the speakers by Tricky, Girlfriend walks back onscreen with a hot dog, referencing the hot dog vendor scene from Madness Combat 6: Antipathy.
"Unloaded":
One of the buildings in the background is the U-Cream shop where the original short, Pico's Unloaded, began.
Pico starts the song with his hands behind his back before pulling out two Uzis, just as he does when confronting the Uberkids in the short.
Partway through the song, Pico starts gunning down Uberkids rapidly while breakdancing, referencing a similar scene from Pico's Unloaded. Similarly, another Uberkid is killed when Pico shoots a rope holding a bus in place, causing it to get run over.
Pico runs out of bullets before he can shoot down the last of the Uberkids, forcing him to uppercut it with his bare hands, mirroring one of the final scenes in Unloaded.
Both versions of the song feature Leitmotifs of Eddsworld's opening theme, as well as "Norway", a song from bbpanzu's Vs Tord mod.
On Hard mode, the song is interrupted by Eduardo, Jon, and Mark (collectively referred to as the "NeighBORES" in-game, referencing Tom's nickname for them). Eduardo's "well, well, well" line and him punching Jon in the face for no reason, as well as battling from behind the fence between his and Edd's houses, all reference "Hammer and Fail", the first episode the neighbors appear in.
If the song is played on Fucked difficulty, Eduardo is replaced by Tord piloting his Tordbot, who also uses voice clips from "The End: Part 2". In addition, Tom enters the scene holding Tord's wanted poster, referencing him discovering it and confronting Tord on why he is on a wanted poster.
During the Fucked difficulty version of the song, Tord is briefly annoyed when Boyfriend sings a short Leitmotif of "Sunshine, Lollipops, and Rainbows", a song that he's shown to hate quite vehemently in the show.
In Fucked difficulty, Tord is defeated at the end of the song by Tom firing a harpoon into Tordbot's cockpit, just as he does in the climax of "The End: Part 2".
"Anywhere, USA":
The stage opens with the Alien crash-landing as he did in the first game, and the FBI immediately sweeping in to confiscate his ship, clean up the mess and reassure everyone nothing happened.
The entire song takes place over the course of the first stage of Alien Hominid all the way up to the Greaseglob restaurant at the pier, with the Alien and Boyfriend traversing the streets at a pace similar to the original game.
All throughout, the Alien is given a fireball powerup by a Fat Kid, jump on an agent's back to bite his head off, slice at them with a knife, and hops in a car to run more agents over to match different mechanics found in the game.
After finishing the song the Alien does a celebratory cheer matching the one he did in at the end of a stage.
If the song is played on Fucked difficulty, then the first proper boss of the game, a mechanical FBI agent piloted by the Install Ball, will drop in to act as the final opponent.
Much like in the original fight, its note presses are accompanied by different strongman poses.
The final blow is a combination of the Alien having shot at the robot in its weak spot for the battle's runtime, and Boyfriend's scrapped "mic throw" attack from the official game.
When beaten, only the eye is left sobbing on the floor as the Alien, Boyfriend and Girlfriend celebrate their victory.
"Roadkill":
In general, the song is a Broad Strokes adaptation of the climax of Tankmen 2, altered to make Steve do most of the heavy lifting in the last minute instead of Tankman (who is too busy singing to make any use of the tank in Steve's place.)
During the opening shot, Tankgirl (from the non-canon Tankmen Infinity) is seen drinking at the watering hole trying to ignore the fight breaking out. The Tankmen's sniper is also passed out with a knife in his back like in Tankmen 2, but enough blood is pooled around his face to suggest that he's actually dead this time around.
The song takes place during a skirmish between the Tankmen and their enemy, with John Captain and Steve getting attacked by the Thugmen mid-assault.
