- Awesome Music: Thanks to Manabu Namiki. For the Saturn port, the rest of the group which would be known as Basiscape joined in the fun.
- The theme of all the flying bosses, Stab and Stomp.
- And pretty much the rest of the soundtrack, as well as the Saturn port's arranged soundtrack Rearrangements of Stage 5's music ("Subversive Awareness") and "Stab and Stomp", anyone?
- Marginal Consciousness. What's weird and scary about this track, is that in the arcade version, it keeps increasing in pitch indefinitely when listened to in the sound test.
- Erupter, the theme of the last boss, Glow Squid. A hardcore techno piece similar to the Hibachi music from Do Don Pachi: Dai Ou Jou. In fact, both games' soundtracks were composed by Manabu Namiki.
- Degeneracy, the Stage 4 theme, is a very catchy track.
- Best Boss Ever: Despite its difficulty, Black Heart is a pretty cool boss. Rule of Cool dictates that you fight it while flying through a thunderstorm at high speeds. The fact that Stab and Stomp, the game's most awesome song is playing in the background, simply adds to the awesome.
- Broken Base:
- Concerning the "Red Ball" feature, which turns aimed bullets into obvious red projectiles (rather than the realistically-colored and hard-to-see ones) and is forced on in some versions of the PCB and can be toggled in the Saturn port. Proponents argue that non-obvious bullets are Fake Difficulty, opponents argue that competitively playing the game entails playing on all defaults.
- The rank system is a major point of contention; some feel that it's well-designed and encourages careful decision-making, but others find it an obtuse mess that's simply designed to take players' money.
- A huge topic of debate is Rev.2016 being a digital-only release. Is M2 doing a disservice to fans by not offering copies that one can hold in their hands and are not at the mercy of DRM or PSN closing down, or is it justified given the cost to print physical copies and the lack of popularity that the shmup genre has in modern times? Keep in mind, the Western shmup community largely has a very cynical take on digital distribution compared to fans of many other game genres.
- Complacent Gaming Syndrome: At the highest levels of play, Gain is the most commonly used character due to his powerful swords that can pierce through enemies and his Area of Effect bomb that can earn the player obnoxious amounts of points from the flamingoes in Stage 2 and Black Heart MKII's mines in Stage 7. Those who are averse to his learning curve may instead use the Golden Bat (the all-buffs version of the Wild Snail) due to its piercing shots and very long bomb duration.
- Cult Classic: The game was released in 1996, and though it has been eclipsed by CAVE, Treasure, and Touhou games in terms of popularity, there are still players who love the game for its surprising depth and countless scoring tricks and continue to dedicate themselves to achieving the coveted "letter" scores or even just trying to clear the game at all. It has one of the most in-depth guides on Shmups Forum, detailing every critical aspect of the game. Its cult following status managed to persist long enough for a 20th-anniversary port on a modern platform to come about.
- Ensemble Dark Horse: Black Heart, the boss of Stage 5, and its MKII version serving as the penultimate boss. Also, the flamingoes in Stage 2.
- Memetic Mutation: Basically any remarks/jokes about what raises rank in Yagawa games, including one person asking "Does pausing the game in the saturn port raise Rank?".
- Most Wonderful Sound:
- The robotic-sounding announcer is always a treat.Shot level up!
Weapon level up!
Special power up!
- That satisfying chime that plays when you pick up a 10,000-point medal, especially when it happens in rapid succession.
- The robotic-sounding announcer is always a treat.
- Nightmare Fuel:
- Listening to "Marginal Consciousness" in the game's Sound Test, or in sound-playing software for arcade data dumps? Don't let it run for more than 3 minutes or the pitch will escalate to seriously creepy levels.
- The way Nose Lavagghin, the first boss, suddenly bursts into flames when you defeat it, especially if you didn't destroy any of its turrets or engines. It suddenly lets off a burst of flame from the main body, and the turrets and engines that haven't been blown up catch aflame with plumes of fire billowing off. Then it glows orange and descends offscreen, small explosions obscuring its form from view. It's just how suddenly it happens that it happens that it almost qualifies as a jumpscare.
- Look at the ground when you fight Mad Ball, the Stage 2 boss. It's a town that's been thoroughly razed to hell and back.
- The way Glow Squid is reduced to the cockpit for the final phase and then flies around frantically spewing every attack it still has can make you wonder if the pilot has just gone completely Ax-Crazy trying to make a Last Stand.
- Polished Port:
- The Saturn port has been hailed as being arcade-accurate, allowing the selection of the Mahou Daisakusen guest characters without a code, allowing resetting of rank simply by opening the options menu instead of resetting the game, a unique control scheme for experimenting with autofire rates, and last but not least, a choice between the original game soundtrack or an arranged soundtrack. Basically, if you can't get your hands on the PCB, this is the next best option, and some would argue that it's an even better one unless you're an absolute purist.
- The Rev.2016 port for Xbox One and PlayStation 4 is even better, having been developed by M2 of Mushihimesama Futari and the 3D Classics series fame. It has most of what the Saturn has, along with many ways to tweak the game experience such gadgets for displaying important real-time data, a Super Easy mode, a custom mode that lets you change individual elements of the game (such as disabling the Dynamic Difficulty system), an Arrange Mode, and four soundtrack options (arcade original, Saturn arrange, arcade remastered, and 2016 arrange).
- Signature Song: "Stab and Stomp!", the air boss battle theme that happens to be the boss theme for Stages 1 and 2 and is also used as the theme of both Black Hearts.
- Stoic Woobie: The Wayne brothers. They construct all kinds of awesome military machines as part of a contract with the government, only to discover their precious machines being used for aggressive warfare. Nonetheless, they take to the "leaden sky" and crush what they made for a living, by themselves. The most they show is some stoic pondering about science and humanity in Armed Police Batrider.
- Tear Jerker: One that will escape most players due to most players ignoring plots in shoot-em-ups, but it's a little heartrending that the Wayne brothers have to destroy their own expertly-crafted machines because they're being used by the power-hungry government and its military for malicious conquest.
- That One Attack: Black Heart's signature dual Spread Shot sweep. It opens up two cannons that shoot out a spread of bullet streams, and then swivels them back and forth very quickly. Serious precision is required to dodge this attack without getting torn into shreds.
- That One Boss:
- Black Heart, both the original, and MKII. Both of them come back in Armed Police Batrider and are even harder! Most notably, when you encounter it in Stage 5, unlike the first four bosses which can be picked apart to disable some of their attacks, Black Heart has no parts that can be chipped off and thus you're forced to bear the full force of its attacks from start to finish. As this tribute to Garegga puts it:Black Heart represents the negation of all of Gareggas tirelessly-established principles. Instead of a collection of armaments to pick apart, you have a core and two wings. The wings are invulnerable too, just to rub it in. Instead of phases determined by parts destroyed, you now have phases determined by core healthwith them only switching after the previous attack completes. Everything about Black Heart is ruthlessly prescriptive, and comes as a shock in this game which up until now has never told you what you ought to do.
- The infamous turret wall in Stage 6, known for being atrociously difficult if you didn't manage rank in the first five stages properly. While it doesn't seem to be classified as a boss by the game, the fact that all game progress stops until it's destroyed means it may as well be one.
- Black Heart, both the original, and MKII. Both of them come back in Armed Police Batrider and are even harder! Most notably, when you encounter it in Stage 5, unlike the first four bosses which can be picked apart to disable some of their attacks, Black Heart has no parts that can be chipped off and thus you're forced to bear the full force of its attacks from start to finish. As this tribute to Garegga puts it:
- That One Level: Stage 6. Your chances of getting through hinge partly on how well you kept rank under control in the first five stages. You'll also need to power up your shot beginning at this stage (as opposed to conservatively powering up in the first five) to survive.
- Said level can also be made easier by jacking rank up high enough that some enemies don't even get a chance to fire.
- Underused Game Mechanic: The widgets you can use in Rev.2016 are all very useful for practice and analyzing runs, but unfortunately most of them are not accessible if you play on a vertically-oriented screen.
- Warm-Up Boss: MD-113 "Nose Lavagghin," the first boss of the game.
- Wake-Up Call Boss: Right after that, SF-5418 "Mad Ball," who comes in the second stage, right after that.
YMMV / Battle Garegga
