Grief Syndrome is a side-scrolling Beat 'em Updoujin game by Twilight Frontier, the makers of the Eternal Fighter Zero series, the Touhou fighting games along with other Touhou fan-games, and Higurashi Daybreak.Grief Syndrome is a fan-game based on the anime and manga series, Puella Magi Madoka Magica. In this game, players can play as Madoka Kaname, Sayaka Miki, Homura Akemi, Mami Tomoe, and Kyoko Sakura across five stages to slay waves of familiars and take down the witch waiting at the end of each stage. Unlike most beat 'em ups, each magical girl's life is dependent on her Soul Limit, which also acts a timer as it depletes over time. If a magical girl has taken some damage, she can automatically replenish her Hit Points for some of her Soul Limit, but dying comes at a greater expense in order to be revived shortly after. Once a magical girl's Soul Limit reaches zero, she is dead for good until a new game starts.The game also features three-player co-op to team up against the hoard of surreal monsters they come across. Unfortunately, Grief Syndrome's multi-player is local only, but fans have created a third-party program called "GSOnline" that enables online-play.The game was released during the 80th summer Comiket in Japan on August 13, 2011 for Windows PC.See also Homura Combat, a Puella Magi Madoka MagicameetsEarth Defense Force fan-game by OHBADO staring Homura Akemi.
Adaptational Badass: Madoka, since she doesn't see much action in the original anime but is a magical girl who fights alongside her friends in this game. To be fair, her incarnations from alternate realities in the anime and the movie demonstrated well enough that she's more than capable of handling herself as an ordinary magical girl.
Sayaka has jumped up from being the weakest fighter in the original series to arguably one of the strongest in the game.
Bonus Boss: Oktavia von Seckendorf appears as an optional boss if Sayaka dies at any point of the game, which makes sense considering her fate in the anime series.
Cast from Hit Points: Using special attacks doesn't exactly take your character's vitality, but it fills a blue portion of the vitality gauge that becomes extra damage if they get hit before (otherwise harmlessly) regenerating the blue health.
Co-Op Multiplayer: Up to three players can team up and fight off the Familiars and Witches, but it's limited to local co-op. Thankfully there's GSOnline, a fan-made program that also online play with people, however there is the program can corrupt your game's save file, so back it up before using it.
Final Death: If a magical girl's Soul Limit reaches zero, she is a dead for the remainder of the game. However in Saya's case, once she dies, she becomes Oktavia von Seckendorf and can fought as an optional boss.
Harder Than Hard: After clearing the game, a new "lap" can played with stronger enemies, which in turn, can also offer more EXP and accelerate character growth. Each lap, though, is increased by lap number by the of power 2 +1 (e.g. Lap 1^2+1=2, Lap 2^2+1=5, Lap 5^2+1=26), and as absurdly high these numbers are, so will the strength the enemies. Note that characters have a level cap of 99.
Harmful Healing: Regenerating health consumes a girl's Soul Limit. In most cases this is either a moot point (the girl has been KO'd in one shot and so needs have a new body generated anyway) or not a particularly worrisome issue (girls start each stage with five-digit numbers of Soul Limit and so a non-KO hit eats only a small percentage of that total — this especially true on earlier laps). It comes around, though, if the girl is low on Soul Limit and gets hurt non-lethally. Heatlh automatically regenerates and eats Soul Limit, and so as soon as Soul Limit reaches zero, she drops dead. Players would rather forego the healing and conserve Soul Limit (it normally depletes at about one per second) for the boss fight... although Kyuubey wouldn't.
Improbable Weapon User: Homura from the earlier timeline of the series uses a golf club for melee attacks and bombs that can also harm allies and herself.
Joke Character: In v1.10, Kyubey becomes playable if there are more players than characters alive. He can't fight at all and can be killed off by the other players.
Also possibly justified in-universe, in what might called a case of Fridge Brilliance: of course Kyubey won't fight. Why would he? He is immortal/there are infinite "hims", and can afford to die any number of times he desires. He'd probably consider fighting a gross waste of energy.
Also, Another Homura. The cute, inexperienced Meganekko damages other characters with her pipe bombs, and her main weapons are a shotgun. a handgun and a golf club, as she hasn't yet acquired the military arsenal available to her more experienced counterpart.
Lightning Bruiser: Sayaka has the highest vitality and lowest Soul Limit consumption per damage taken, which makes sense since she's the purest melee fighter in the game. She can hack enemies to death at lightning speed and still take hits like a tank in the lower laps with little problems. She turns into a Glass Cannon the higher laps however, since every magical girl would be knocked out in one hit, and going melee would be a good way to get yourself killed.
Meganekko: Homura from the earlier timelines in the anime series added in v1.10.
Mook Maker: The first of Charlotte's forms has no attacks besides spawning unlimited familiars until her lifebar is drained.
More Dakka: Mami and Homura, and to a lesser extent, Madoka.
Multiple Endings: Ten to be exact, depending on who lives and/or dies at the of the game.
Reset Button Ending: If the player finishes the game in a way that doesn't meet the requirements of certain specific endings, the ending shows Homura waking up from her hospital bed just as in the anime series.
Nintendo Hard: The third level in the game has an insane amount of hazards such as electrified floors, huge gaping pitfalls, indestructible projectiles, and enemies that drop televisions on your head and fly at you when you can't see them. And on higher laps...
Shown Their Work: The Witch Runes in Kirsten's damaging TVs read "thunder" when active.
Wedding Day: Two of the game's ending have Homura marrying Madoka (which to Madoka, seems like a Fate Far Worse Than Death) if they are the only ones to survive in the end, and Sayaka marrying Kyoko (which they lived Maybe Ever After) if they survive in the end instead.
