Multisoft All-Star Nitro

Multisoft All-Star Nitro is a fighting game developed by Game Arts and Marvelous Games, with assistance from Koei Tecmo, and published by Multisoft cross-platformed (released for the Nintendo Switch, Xbox One, PlayStation 4, Nintendo 3DS, PlayStation Vita, and PC). Like the previous games, Multisoft All-Star Nitro is a non-traditional fighting game where players use different attacks to weaken their opponents until their health is completely depleted. The games are crossover titles that feature characters, items, music, and stages from various Multisoft franchises, including Delta Cross, Superstar, Dimenbeasts, Cross Serpent, Alien Killer, Star Maidens, Red the Dragon, Solar Jester, and Monster Hero among others, as well as from several third-party franchises, including Burst Arts' Petropolis, O.K. Buster, Robot Summoner Kite, and Power Battlers. New features include having up to eight players fighting at a time on the console versions, post-release downloadable content including additional fighters and stages, and customizable special moves unlockable for every non-DLC character.

Gameplay
Like in previous games in the series, Multisoft All-Star Nitro is a multiplayer fighting game in which the players use various attacks, techniques, and items to deal damage to their opponents and knock their opponents out of the arena. As a character's health decreases, they become weaker when attacked, and may eventually be weak enough to be knocked out. To assist players during battle, items sometimes appear on the battlefield if turned on, most of which represent the various video games represented in the series. A new item called a Nitro Coin allows players to use a powerful, character-specific move, otherwise known as the "Nitro Drive," replacing the use of Flash Stones. Another item is an Assist Figure, which summons various non-playable characters from a represented series onto the field to assist the summoner. Like its predecessors, Multisoft All-Star Nitro features collectible in-game figures based on characters or items seen in various Multisoft or third-party games. Each stage now features an alternate Alpha form, which replaces the stage's layout with a flat surface with ledges on both sides and removes all stage hazards, similar to the stage "End of The World", which is a medium-sized stage that is completely flat and features no hazards. Certain stages, collectible trophies, and game features are exclusive to each version of game, with the console versions primarily featuring elements taken from home console titles and the handheld versions taking elements primarily from handheld titles. Both games feature revisited stages from past entries in the series and new stages representing newly introduced properties or recent entries in existing ones.

Both versions of the game support local and online multiplayer. Whereas local and online matches with friends have fully customizable rules, online matches with strangers are divided into two modes: "Funtime" and "Serioustime." Funtime features random stages and items, with time matches only and Omega stages omitted, while Serioustime features stock matches with no items exclusively on Alpha stages and features both standard Battles and 1-on-1 battles, all of which the player's wins and losses are recorded from Serioustime. Customized characters cannot be used in online matches against strangers. Additionally, solo play once again features Arcade mode, which features an intensity setting directly influenced by Malik Brooks's previous project Velvet Hunters: Rebellion, in which players can make the game more difficult by spending in-game currency in order to earn greater rewards. Both versions share two new modes. Target Attack has players beat up a ticking bomb before launching it into a set of targets, with the goal of earning as many points as possible by causing chain reactions. Figure Attack has players clear out falling crates to build up a Fever meter and quickly earn new trophies and customization items.

In addition to a moderation system to prevent grieving, the game features an online ranking system called "Global Multi Power" for a player's solo mode score, which shows how many other players someone has outscored, rather than listing their position on a leaderboard. Although the game does not feature a ranking system for online matches, matchmaking between players of similar skill levels was introduced. Online also features Spectator Mode, where spectators can place bets on other players to win more gold, and Conquest, in which players can support selected characters by playing as them online, earning rewards if their supported team wins, and earning bonus rewards for going on a win streak.

Platform-specific features
The handheld versions feature stereoscopic 3D graphics with optional cel-shaded outlines to make the characters more visible. The game also features two exclusive modes; Nitro Siege and SpinRumble. Nitro Siege, based on the Circuit Trial mode from Bomb Strike Z, has players navigate an open environment, fighting computer-controlled enemies to earn stat-increasing power-ups, before facing each other in a randomly selected match, such as vertical or horizontal races against each other or battles with various special rules. SpinRumble is an online-based game in which players control a top on a top-down board and attempt to knock their opponents out of the arena.

The console and PC versions feature high-definition 1080p graphics and a special mode that allows up to eight players simultaneously. This mode is restricted to certain larger stages and cannot be played online, though additional stages were made available for eight players via post-release update patches. Various modes from the handheld versions, such as Arcade mode, feature various changes in the console and PC versions, with some modes allowing two players to play cooperatively or against each other in other modes. These versions also feature three exclusive new game modes; Cross Shooter, Special Orders, and Mission Mode. Cross Shooter is a shoot 'em up-type mode in which up to four players assemble a team of fighters that they pick up after shooting capsules. Players have the ability to change the length of the game, the number of turns, and choose if they allow to have custom characters on the board. In this mode, players earn stat increasing power-ups, triggering various battles and events along the way. Special Orders is a series of challenges set by God King and Goddess Queen, which players can attempt to earn rewards. Each time a battle is won, the reward and the stakes will rise, but if a round is lost, all accumulated prizes will be lost. In Mission Mode, one or two players can participate in themed challenges, moving along the path by completion. Returning features unique to this version include Special Nitro, allowing for unique rules, Stage Builder and Photo mode, which allow players to create personalized stages and dioramas, and demo versions of classic games in a "Masterpieces" gallery.

Roster
Multisoft All-Star Nitro features a roster of 77 playable characters (70 on-disc and 7 available as downloadable content) taken from both Multisoft's first-party franchises and some third-party franchises, including returning characters Thunder Storminski and Erla Vahn. The base game includes 19 newcomers to the series, such as Jessica from Step Craze, Monster Hero's Chester Waldillo, Ryan from the Gale of Magic series, Reo Horikawa from Dimenbeasts AX (with Dimknown as an assist), and Clash Arts' Kite as a guest character. Some characters such as Vars and Jessica have different genders and alternate character skins, which are selected in the same manner as alternate colors. Drew Baker, who first appeared in Multisoft All-Star Evolution, makes his return to the roster after his absence in Overdrive. Nugget and Tender were originally planned for inclusion, but were removed due to the technical limitations. Gin and Batman are also absent following their appearances in the previous game.

Boss Characters
Aside from the main bosses, this game introduces Stage Bosses. There are a total of four, each appearing on one specific stage at certain times, hindering the battle until they are defeated.

Genbranch: the only boss available in both versions, appearing on the Ruins of Retribution, and was also the first stage boss confirmed. He is invulnerable in every area except his legs, and can transition between areas of the stage.

Gray Blob: the only portable version exclusive stage boss, appearing on Dual Blobs 4. It first appears offscreen, and can clear certain colored blobs give bonuses to fighters. Eventually it flies onscreen where it can be attacked; once attacked a certain amount, it will fly back offscreen.

Torubog: the stage boss of Planet 20 Vurwen. Unlike the other stage bosses, if he is damaged a certain amount by one player, he will fight on their side. If he is KO'd, the player who KO'd him gets an extra point; even the player Torubog is assisting can get a point from this. Once damaged enough, Torubog will fly to one of the two roofs of the stage and absorb purple energy, turning into Skull Torubog, who is more powerful and has slightly different attacks.

Aron Koda: teased at the end of Tyson's reveal trailer as the stage boss of Snowy Streets. He attacks from the top of some buildings and will eventually jump into the battlefield, where he can damage parts of the stage and be KO'd.

God King: the standard boss of the game, from difficulties 1-4. He continues to be fought at the end of Arcade Mode on The End of the World and has new attacks; however, on high enough difficulty settings he will be defeated by Rebus near the beginning of the fight, and the player will defeat Rebus in God King's place.

Goddess Queen: She continues to be fought alongside God King at the end of Arcade Mode on The End of the World, and the two will appear together at the beginning of the battle; however, the conditions are now different. In the portable version of the game, the player gains the choice to fight her when on difficulty 5 or higher in return for more rewards; on difficulty 8 or higher, the player has no choice but to fight Goddess Queen. In the console version, the player will always fight Goddess Queen as long as the difficulty is 3 or higher. However, in both games, if Goddess Queen (and God King) are fought on difficulty 5 or higher, Rebus will appear in their place soon after the beginning of the battle.

Rebus: The main antagonist of Multisoft All-Star Overdrive returns as a boss. She has many devastating attacks, most dangerously her Lunar Quake which can instantly KO and are hard to dodge, but most of his attacks have a large amount of start-up lag. In both versions, if the difficulty is set on 5, she will attack God King and Goddess Queen so she can fight you instead. However, in difficulties higher than 6, she will transform into Lunar Divinity Rebus after damaging her at a point in time.

Lunar Divinity Rebus: a transformation of Rebus, and appears as a secret final boss in Arcade Mode only when the difficulty is set to 7 or higher, after God King and Goddess Queen are defeated and Rebus is damaged enough. She possesses several apparitions that are fought in order: the spaceship-like Lunar Airship, the sea monster-like Lunar Beast, the knight-like Lunar Edges, a shadow duplicate of the player character named Lunar Shadow, a massive sub-stage of its own called the Lunar Labyrinth (exclusive to the console version), and finally Rebus herself. What forms are fought depend on the Intensity; numbers vary between versions, but in general the higher the Intensity setting the more forms that are fought, causing Lunar Divinity Rebus to have more HP overall and take longer to defeat. After all previous forms are defeated, Rebus will appear; she is normally completely defenseless, but if not defeated quickly enough, she will unleash five quakes, each powerful enough to cause a one-hit KO.

Stages
The stages differ depending on the version. The handheld versions feature 42 stages total, 7 of which are unlockable, shown in bold, and 8 of which are downloadable content. The console versions features 55 stages, 6 of which are unlockable, shown in bold, and 9 of which are downloadable content. Bold and italic text denotes stages that are unlockable in one version, but a starter/downloadable stage in the other. 13 stages appear in both versions (with some having changes), however the majority of stages are exclusive to each version, with handheld stages primarily pulled from handheld games and console stages from console games (though, there are some exceptions). In addition, this is the first game where stages from multiple past games return at once.

All stages now have an optional Alpha Form, changing their layout to be similar to End of the World - some have walls that go all the way down to the bottom blast line, while others are basically floating islands.
