'''''Grief Syndrome''''' is a side-scrolling BeatEmUp [[DoujinSoft doujin game]] by Creator/TwilightFrontier, the makers of the ''VideoGame/EternalFighterZero'' series, the ''VideoGame/{{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, ''Anime/PuellaMagiMadokaMagica''. 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 HitPoints 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, [[FinalDeath 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.

!!''Grief Syndrome'' features trope examples of:
* ActionGirl: All five main characters, of course.
* AdaptationalBadass: [[BadassAdorable 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 [[PuellaMagiMadokaMagicaTheMovieRebellion 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.
* BonusBoss: [[spoiler: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.]]
* {{BFS}}: [[spoiler: Oktavia von Sekendorf.]]
* CastFromHitPoints: 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.
* CheckpointStarvation: There's no checkpoints at all, so dying means starting the stage over.
* CoOpMultiplayer: 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.
* CosmeticAward: The game features [[PlayStationNetwork PlayStation Network]]-esque trophies for accomplishing certain goals in the game.
* DeathFromAbove: Madoka's special points her bow upward and rains arrows down around her. It gets to {{game break|er}}ing levels when the bosses are large enough to take up most of the screen.
* DeathOrGloryAttack: In near-death situations, the character's special attack can be come this.
** Mami's special is this normally, because it puts a large amount of her HP into the attack that any hit will seriously injure (if not outright kill) her if she doesn't let her blue bar reduce itself.
* DiedHappilyEverAfter: [[spoiler: Mami Tomoe]] gets this if she's the only one to die.
* [[spoiler:DownerEnding: If Mami is the only magical girl to survive at the end of the game, a still image of her sitting all alone at a table with tea and snacks prepared for her friends, who are all dead.]]
** [[spoiler:Kyoko also gets one if she's the only magical girl that dies, who sits all alone with a depressed look on her face while everyone else happily goes on about their lives.]]
* [[spoiler:EverybodyLives: [[ExactlyWhatItSaysOnTheTin It's exactly what it says]] if nobody died at the end of the game.]]
* FinalDeath: If a magical girl's Soul Limit reaches zero, she is a dead for the remainder of the game. [[spoiler:However in Saya's case, once she dies, she becomes Oktavia von Seckendorf and can fought as an optional boss.]]
* FlunkyBoss: All of them, except [[spoiler:[[BonusBoss Oktavia von Seckendorf]].]]
* GameMod: There are a few. [[http://wiki.puella-magi.net/Talk:Grief_Syndrome Most can be found on the Madoka wiki.]]
* GirlyRun: Madoka and Mami.
* GlassCannon: Kyoko plays like this, offering high damage, good reach, and lots of [[InvulnerableAttack invincibility frames]]... but a low Soul Limit and costly regeneration.
* GolfClubbing: [[spoiler:Another Homura's WeaponOfChoice.]]
* HarderThanHard: 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.
** One of the only stories that [[JustifiedTrope actually have an in-universe explanation]] for a [[NewGamePlus New Game+]], due to Homura going back in time to try and make things better an unknown (implied to be at least several hundred) number of times.
* HarmfulHealing: Regenerating health consumes a girl's Soul Limit. In most cases this is either a moot point (the girl has been [[OneHitKill 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... [[FridgeBrilliance although Kyuubey wouldn't]].
* ImprobableWeaponUser: [[spoiler:Homura from the earlier timeline of the series uses a golf club for melee attacks and bombs that can also harm allies and herself.]]
* JokeCharacter: 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 FridgeBrilliance: ''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, [[spoiler:Another Homura. The cute, inexperienced {{Meganekko}} damages other characters with her pipe bombs, and her main weapons are a {{shotgun|sAreJustBetter}}. a {{handgun}} and [[ImprobableWeaponUser a golf club]], as she hasn't yet acquired the military arsenal available to her more experienced counterpart.]]
* LightningBruiser: 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 GlassCannon 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.
* [[spoiler:{{Meganekko}}: Homura from the earlier timelines in the anime series added in v1.10]].
* MookMaker: The first of Charlotte's forms has no attacks besides spawning unlimited familiars until her lifebar is drained.
* MoreDakka: Mami and Homura, and to a lesser extent, Madoka.
* MultipleEndings: Ten to be exact, depending on who lives and/or dies at the of the game.
* [[spoiler:ResetButtonEnding: 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.]]
* NintendoHard: 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. [[UpToEleven And on higher laps...]]
* ScoringPoints
* ShownTheirWork: The Witch Runes in Kirsten's damaging [=TVs=] read "thunder" when active.
* [[spoiler:WeddingDay: Two of the game's ending have Homura marrying Madoka (which to Madoka, seems like a [[FateWorseThanDeath Fate Far Worse Than Death]]) if they are the only ones to survive in the end, and Sayaka marrying Kyoko (which they lived MaybeEverAfter) if they survive in the end instead.]]
* ZettaiRyouiki: Sayaka, Mami and Kyouko.
