Shout Out / Sword Art Online Alternative: Gun Gale Online

• In the second episode, the covers of two Digimon games can be seen in a video game store.
• While converting between games, one of the games LLENN tries gives her an alien avatar which looks suspiciously like a female Frieza.
• The leader of Team SHINC is named Eva, but her teammates call her Boss.
• The leader of Team ZEMAL dresses up similarly to John Rambo with the red headband, although he uses a M60E3 GPMG.
• When thinking of who to team up with for the second Squad Jam, Karen complains that "LLENN doesn't have many friends."
• In Squad Jam 2, the leaders of the 7 allied teams◊ are pretty clearly designed after the main cast of The Expendables and Universal Soldier.
• The names of Clarence and Shirley are a nod to Airplane! and Leslie Nielsen's famous line.
• When the dome battle begins in Volume 3, one of the tavern patrons watching the fight comments that the opposing teams shooting randomly into the brush staging a fake battle to bait out LLENN and Fuka reminds him of a certain movie about an invisible alien who hunts humans for sport.
• The designs of Team T-S◊ look a lot like Federation Marines from the Metroid Prime series.
• In Volume 3, when the last member of PM4 is throwing beds down the stairs to slow down MMTM, one of the spectators in the pub comments it's like an old video game where a gorilla throws barrels down platforms.
• M activating a plasma grenade and preparing to blow himself up along with Pitohui is reminiscent of Vasquez and Gorman, complete with her hand covering his on the grenade.
• The Mook Horror Show when Team MMTM gets slaughtered and seeing Pitohui make her entrance with a red Photon Sword is practically lifted right out of Rogue One.
• Pitohui's Photon Sword itself is red and double bladed, making it a reference to Darth Maul... at least for a moment.^note The Muramasa F9 is a single-bladed weapon, but its special ability is to switch the blade from one emitter to the other on the opposite end, so it's only double-bladed for the brief period when the transfer is in progress.
• After M & Pitohui commandeer one of MMTM's Humvees to chase after LLENN, she starts kicking M to drive faster and screaming "Hi-Yo, Silver!"
• Later, she's standing on the roof of the Humvee, in the Captain Morgan Pose with her sword pointing ahead, imitating the Warhammer 40,000 meme of "Drive me closer! I want to hit it with my sword!"
• In Volume 5, Team BKA are a team that emulates the look of post-apocalyptic raiders. The narrative outright compares them to "a famous old movie about violent roving gangs in a post-nuclear collapse" and "a famous old kung-fu manga inspired by that film series." Just to make sure there's absolutely no doubt as to which film is being referenced, we get this golden line:
  They took their “madness to the maximum” in pursuit of the aesthetic.
• During the final battle of Squad Jam 3, LLENN tells Pitohui "I have the high ground!"
• In Volume 6's first chapter, Miyu references a "crazy American game where you commit grand theft and hijack cars and stuff, I'm running over innocent pedestrians all the time." On another level, this is doubly appropriate as the context of the conversation is Karen wondering whether it's morally right for her to keep playing GGO, being a game where you shoot and kill people, and Miyu immediately shoots that argument down and reminds Karen there's a big difference between reality and games. In real life, GTA is one of the go-to video game poster child scapegoats of Murder Simulators purportedly causing mass shootings and violence among young people.
• In Chapter 3 of Volume 6, LLENN accidentally runs right into Boss and knocks herself to the ground, and the first thought that runs through her mind is "Oh, I'm dead. RIP. Watashi wa mou shindeiru."
• At the end of Chapter 13 in Volume 9, Fuka pulls up on a bicycle while LLENN was just lamenting her absence, and says, "Kept you waiting, huh?"
• In Chapter 17 of Volume 9, while riding on a freight train stolen by LPFM, Boss re-enacts a scene from one of her favorite movies by standing on the locomotive's front deck and ropes Rosa into playing along. Pito then has to yell at "Jack and Rose" to get back inside.
• The final chapter of Volume 9 is titled, "The Melancholy of Karen" in the localization (a more direct translation would be something like "Karen's Gloominess").
• In Volume 10, the fifth chapter ends with Fuka giving LLENN a pair of snow shoes so she can zip across the snowfield and finish the third ordeal just in time before the time limit ends. LLENN exclaims "Fuka, I love you!" to which she just replies "I know."
• The sixth chapter of Volume 10 starts with LLENN completing the third ordeal and entering an otherwise floating featureless door to proceed to the fourth ordeal. The narration says it's just like "the Anywhere Door from that famous cartoon."
• Volume 11 begins Squad Jam 5, which starts the tournament off in a battlefield with a thick misty fog obscuring everyone's vision. Naturally Fuka just has to make a movie reference about it, which even cracks up Clarence.
  Fuka: "Hey guys... if you think about it... we're just like gorillas... Get it? Because we're-"
  LLENN: "Gorillas in the Mist, yeah."
  • LLENN brings out her inner Shakespeare as she ponders to herself what to do when an unknown voice calls out to her in the mist.
    To run, to hide, or to speak — that is the question, LLENN Hamletted.
  • In Chapter 4, during a scene when LLENN asks Fuka what kind of person Vivi is, Fuka shamelessly quotes word for word Pixy's famous description of Cipher from the intro cutscene of Ace Combat Zero: The Belkan War. The narration even points it's ripped directly from "a certain famous flight combat game."
  • When LLENN asks Vivi how she was so well-prepared for SJ5, the latter mentions that the tournament sponsor loves to recreate situations from his own novels and outright references one called "Misty's Journey".
• Volume 13: In Chapter 11, after discovering the castle has an invisible ceiling that prevents shooting over walls, Fuka puts away her grenade launchers and prepares to switch to using her pistol. LLENN, recalling how Fuka shoots, grumbles "Don't do that. You'll put someone's eye out."
  • The start of Chapter 12 sees a member of Team T-S getting mercilessly mowed down by Team ZEMAL's nigh-limitless firepower. While his armor is strong enough to withstand the bullets, the kinetic impact from hundreds of rounds is still damaging the player within. One spectator watching from the pub swears he saw this scene before in RoboCop (1987).
  • Chapter 13 sees the pub crowd placing bets who will be victorious in the assault on the castle tower, with the remaining members of Team LPFM and SHINC on one side versus whatever stragglers from most of the other participants of Squad Jam 5 are left. As the latter group doesn't have a name since they're made up of men from a bunch of different teams, one guy in the pub christens them "Team Greedo."
