Video Game / O.N.G.E.K.I.

Following

Yep that's right, SEGA staff thought to combine two of the most infamously challenging single-player game genres into a single game.

The core gameplay features a panel with two sets of three face buttons, with one set on the left and the other on the right, a large analog joystick in the center that can be moved horizontally, and two buttons on the inner walls of the cabinet. The player controls a party of three on a "hallway" perspective as they scroll down the chart. Upon reaching red, green, and blue notes, the player must hit the corresponding color of button (doesn't matter which side of buttons you hit, at least until a certain point in the difficulty scale). Likewise, there will be purple notes on the edges of the lanes; these must be hit with the correct button. Finally, the player uses the stick to move their team, in order to collect yellow Bell items for bonus points and health, avoid pink and purple bullets that will damage the lifebar when hit, and keep their team on the lanes whenever they narrow and twist, because if the player goes off-course, they will be unable to hit any notes until they get back on-track.

In addition to all of this, each song has an associated enemy you face off against. You start off defeating Mooks called Ongeki Nekos, and then partway through the song, the boss character of the song appears. Hitting notes will deal damage to the current enemy character in proportion to how accurate the note was hit and the strength of the player's team. If the player runs out of health, the song ends prematurely and they lose. If they deplete an Ongeki Neko's health, another one will take their place, and if they defeat the boss, provided the player doesn't fail out too along the way, the player wins. Otherwise, the song ends in a draw. Playing songs will level up the team members' affection and experience levels, allowing them to stand better chances against tougher enemy characters.

Unlike other arcade rhythm games, which typically give the player a fixed number of songs per credit, this game uses a GP system. Inserting credits adds GP and inserting multiple credits may grant the player bonus GP (in addition to the amount of GP the player naturally gets from each individual credit), depending on operator settings. Playing a song uses up a set amount of GP, as does extending the pre-song menu timer. After every song, the player can choose to keep going provided they have enough GP for another song or the money to buy-in extra GP, or end their session and convert unused GP into Money, a currency used for various features.

The game also has a companion cabinet, the Card Maker, which is where players can attempt to roll for new character cards of varying rarity and power, as well as print physical versions of their cards; these cards can be slotted into the cabinet to quickly access that card in-game, as opposed to navigating menus to select it. The Card Maker also has some functions for CHUNITHM and maimai.

ARE YOU READY? Let's SHOOT!

• Anti-Frustration Features: GP is bought with coins and is used up when playing songs. A pittance of GP can also be used to extend the song selection timer.
• Boss Battle: At a fixed point in each song, the Ongeki Nekos stop appearing and the song's boss character challenges you. If you can deplete their health before their song ends, and then make it to the end without running out of your own health, you win the battle.
• Bribing Your Way to Victory:
  • Before starting a song, you can use a Jewel Boost to multiply the number of Jewels you earn from playing the song by a factor of 2, 3, or 9, at the cost of additional GP.
  • In versions prior to Re:Fresh, you can spend an additional 10 GP to play a locked Master chart if you haven't S-ranked the Expert chart for the same song yet. If you get an S rank on the Master chart this way, it will become permanently unlocked as if you did the feat on Expert. As of Re:Fresh, Master difficulty is available by default, as long as the corresponding song is unlocked.
• Bullet Hell: The game has pink orbs on the lanes that have to be avoided, coming in rather dense groups on the higher difficulties. Notably, this is the game that has True Final Boss tracks from CAVE games!
• Darker and Edgier: The main story from the fourth chapter, the School Election arc, takes a darker turn pitting our Shooter girls with Game Changer antagonist Setsuna Sumeragi who wants to overthrow the RBP and restore Kanazaka Academy’s reputation with negative ONGEKI to take advantage of people’s’ bad feelings such as hatred, envy, resentment and anger.
• Flawless Victory:
  • Hitting all notes with no Misses is a Full Combo. Hitting all notes with only Breaks or Critical Breaks is an All Break and takes priority over an FC.
  • Collecting all of the Bells on the chart is a Full Bell, and can be awarded in conjunction with either of the above two.
• The Computer Is a Lying Bastard: Some Lunatic charts have a difficulty rating of 0. Anyone who actually expects a Zero-Effort Boss will be Instantly Proven Wrong, as they're just as hard as other Lunatic charts. This is mainly meant for charts that defy the balance of conventional charting, as charts with a rating of 0 do not affect the player's rating.
• Game Over: Notably, unlike the other two games in the Performai trilogy, it is possible to fail out of a song in the middle of it in normal play (i.e. without using a skill or modifier), if you run into too many bullets.
• Gimmick Level: Some songs have Lunatic charts, which employ all sorts of mechanics not found in "normal" charts, such as making the chart lanes bounce back and forth or having a heavier emphasis on dodging bullets than hitting notes. Some songs, most notably the CAVE crossover tracks, only have Lunatic charts (i.e. no Basic, Advanced, Expert, or Master).
• Gratuitous English: The song "GODLINESS" has English-language lyrics, but the singer is clearly using Japanese enunciation rather than sounding fluent in English.
• Harder Than Hard:
  • Master above Expert, just like the other two games in the series. O.N.G.E.K.I.'s iteration of Master difficulty is notable in that while the lower difficulties usually only have three lanes of notes that can be activated by face buttons on either side, Master charts often have six lanes; during the six-lane segments you have to use the correct side to get credit.
  • Lunatic charts, which either are straight "harder than Master" charts or use gimmicks not found in more conventional charts.
• Money Multiplier: Before starting a song, you can spend extra GP to multiply the number of gems you earn from completing the song.
• Mythology Gag:
  • When reaching the boss segment of "The world of spirit" (which is a Lunatic-only track), the Boss Warning Siren from Dariusburst plays and the text "WARNING! A HUGE BATTLESHIP THOUSAND KNIVES IS APPROACHING FAST" appears, followed by the "boss enters the screen" sound from the same game.
  • "MEGALOVANIA" features many references to its source game Undertale, especially in its Lunatic chart. Examples include (Late-Arrival Spoilers for Undertale) notes that appear before the song actually starts, lines forming white bones that must be avoided to avoid damage and blue bones that must be passed to again avoid damage, the Undertale battle command buttons appearing as lines in the chart, and recreations of many of Sans's attacks, including his infamous penultimate attack. On Lunatic, the boss enemy, a level 1 Ongeki Neko, can only be actually damaged on the very last note, just like how in Undertale, Sans can only finally be damaged — lethally, even -- at the very end of his fight.; in both cases, the target takes a massive amount of damage (in O.N.G.E.K.I., due to this being the only note in the boss sequence; in Undertale, due to the Player Character having grown insanely powerful as a result of being on an omnicidal rampage).
• Painting the Medium: Happens very frequently in Master and more especially Lunatic charts.
  • The Lunatic chart for Saishuu Kichiku Zenbu Koe has some of the vocalisations painted in bullets.
  • The last lyric of Greenlights Serenade by Omoi in Master has the megaphone part of Mika Pikazo's Hatsune Miku illustration for Magical Mirai 2018. Lunatic takes it a step further by making the notes all green-coloured for the lyrics “照らし出して！グリーンライツ 遥かな未来を” in addition to adding the logo for Magical Mirai 2018 at the last lyric, with the total note count being 2018 (the year the song was released and the Magical Mirai edition the song was released for) and the total amount of bells being 39 (the Goroawase Number for Miku)
  • Like in almost all of SEGA’s rhythm games featuring it, Dance Robot Dance by Nayutalien has patterns related to the “up, side, up side down” part.
  • The Lunatic chart for Jingle Bells has notes only in red and green, colours related to Christmas, and the total numbers of notes and Bells are respectively 1225 and 2512, referencing Christmas Day, on December 25.
  • During the middle of Transcend Lights Master, three lines of red, blue and green of the button colors, representing the Fire, Aqua and Leaf Elements of the shooters, splitting into additional lines corresponding to the amount of shooters for each Element (including Setsuna which defaults at Fire) before changing to the image colour of each character with Setsuna sorted after the Aqua characters.
• Power at a Price: One of Setsuna's SSR cards gives a significant boost to your damage output (and thus Battle Score), but it also causes you to lose 3% of your health every time you miss a note, when normally you can only lose health by toucing enemy bulelts or lasers. As such, it effectively serves as this game's version of the rhythm game "hard gauge" archetype.
• Rank Inflation:
  • Like in other SEGA rhythm games, the ranks go up to SSS+.
  • The judge ranks go, in ascending order, Miss, Hit, Break, and Critical Break. Certain modes also add Platinum Break over Critical Break.
  • The Platinum Score star grading system introduced in Re:Fresh appears to top out at 5 stars, which is the highest possible grade for Rating calculation purposes. It is possible to earn a grade of five rainbow stars by achieving 99% Platinum Score, although this does not contribute any further Rating compared to a regular 5-star.
• RPG Elements: This game is very heavy on them, featuring character cards that can be obtained from the Card Maker gacha, provide buffs such as better defense, higher attack power, and elemental boosts, and which can be leveled up. That said, the core rhythm game aspect is entirely playable without having to focus on cards, as cards do not really influence Technical Score or Platinum Score; they most they do is give you more defense or health to avoid ending the song prematurely from too much damage.
• Scoring Points:
  • First, there is what the game simply calls Score, which is based not only on how well you hit notes but also how powerful your team's cards are. If you've played gacha-based mobile games like Love Live! School idol festival and BanG Dream! Girls Band Party!, this will sound famliar.
  • Second, there is Technical Score, which is a more conventional system that is based only on your performance (cards have no impact). Up to 950,000 points can be earned from hitting notes: Critical Break awards 100% of the note value, Break awards 90%, Hit awards 60%, and Miss awards 0%. The remaining 60,000 is earned from collecting Bells. This makes for a maximum score of 1,010,000 points (i.e. 101%). Finally, each time you take damage, you lose 10 points. This is notable for a game with a gacha system, as mobile rhythm games with gacha elements typically have only card-based score in order to encourage players to mass-roll for rare cards as a tradeoff for being "free-to-play".^note Whereas in this game, even if you don't use the gacha at all and just focus on the rhythm game aspect, you're still paying to play the game, so pulls or not, you're making revenue for the arcade and the publisher.
  • Finally, R.E.D. introduces the Platinum Score system. A new judge rank, Platinum Critical Break (or simply Platinum Break, and which is indicated by the "CRITICAL BREAK" text having a white glow), is added and which is worth more than a regular Critical Break. Platinum Breaks add 2 points; Critical Breaks^note i.e. Critical Breaks without the telltale shine for a Platinum Break, and which are tagged with "FAST" or "LATE" if FAST/LATE display for Critical Breaks is on add 1 point; Breaks, Hits, Misses and collecting Bells are worth nothing; and taking damage or missing bells takes away 2 points. Platinum Score was originally exclusive to Master and Lunatic charts, but Re:Fresh makes it available for all charts and incorporates Platinum Scores into the revamped player rating system.
• Single-Stroke Battle: The boss phase of "MEGALOVANIA" on Lunatic only begins at the very last chord of notes, represnting the source game's Sans boss fight, where he can only be hit at the very end, and is promptly defeated in one hit.
• Surplus Damage Bonus: Upon defeating the song's boss, the song will keep going but you will start to rack up an Over Damage bonus, which can net additonal jewels.
• Unexpected Gameplay Change: The Lunatic charts for the CAVE crossover tracks focus less on hitting notes and much more on dodging bullets. "Toua -O.N.G.E.K.I. MIX-" even has you fight the boss by holding down one button while focusing on dodging bullets, just like actual DoDonPachi boss fights!
• Unlockable Difficulty Levels: In versions prior to Re:Fresh, Master difficulty must be unlocked by achieving an S rank on the song's Expert chart. It can alternatively be played once for an additional 10 GP (for a total of 50 GP to play the song, as opposed to the usual 40 GP); if you S-rank the chart on this run, it will also be unlocked permanently, without needing to pay the extra 10 GP again for subsequent plays. Starting with Re:Fresh, Master is available without any prerequisites (other than the song itself being unlocked) and no longer costs extra GP.
• We Win, Because You Didn't: Reaching the end of the song without defeating the boss results in a draw rather than winning outright. This is still much better than a loss, which is caused by running out of health (from hitting too many bullets) and which cuts the song short, depriving you of a lot of potential jewels, Score, and most importantly, Technical Score. Usually a draw happens because even though the player had the skill to avoid damage, they didn't have powerful enough cards to deplete the boss's health.

YOU WIN
