DynaMarisa 3D is doujin Third-Person Shooter game by Twilight Frontier. It stars Marisa Kirisame and doing what she does best: blowing stuff up. DynaMarisa 3D is essentially Touhou Project meets Earth Defense Force, but it does have some merits of its own to set some gameplay differences from the game it's based on. As the "3D" in the title implies, the game be played with stereographic 3D visuals if the user's PC uses a video card that supports it.
The story premise of DynaMarisa 3D has Marisa trying to break into the Scarlet Devil Mansion to "borrow" some books from Patchouli Knowledge's library, as usual. However, this would be the day when Marisa's book-borrowing days would be turned up-side down as she is surrounded by heavily-armed fairies and ant-like robots all under Patchouli's command. Under her orders, her army of robots and fairies lets loose with a barrage of gunfire to teach Marisa a lesson. Humiliated, Marisa flees from the scene but she wasn't giving up without a fight as she swore revenge against Patchouli to take down her legion of mooks by forming army of faires of her own and arming herself to the teeth with an arsenal of weapons, thus the Patchouli Defense Force was formed.
The game was released on May 1st, 2011 for Windows PC during Comic 1☆5. The game later received a fan-made English patch by the translators of Labyrinth of Touhou, which can be downloaded here (requires v1.02).
DynaMarisa 3D tropes includes but are not limited to:
- A.I. Is a Crapshoot: Star Patchouli and, by extension, the entire robot army, goes rogue halfway through the game.
- Artificial Stupidity: The enemy's pathfinding ability is less than stellar, and they can often be thwarted by a simple staircase. This can be exploited to clear some stages on higher difficulty before you really should be able to.
- Big Creepy Crawlie: killer robotic bugs.
- Big Damn Heroes: At the game's final stage, Sakuya, Remilia, Flandre, and Patchouli show up to back Marisa up when Star Patchouli pulls a One-Winged Angel.
- Brought Down to Normal: The Star Patchouli presumably exudes a field that prevents the use of magic, putting this trope in effect for the entire Scarlet Devil Mansion.
- Bullet Hell: It's a Touhou game based on Earth Defense Force after all.
- Die, Chair, Die!: Do you hate seeing that dinning table with that perfectly delicious cake on top of it? Nuke it.
- Dual Boss: Stage 22 has Marisa pitted against two robo-Patchoulis, one of each type.
- Excuse Plot: Just so Marisa can lay waste to robot bugs, heavily-armed fairies, and furniture.
- Everything Breaks: You can gun down giant vases, paintings of a wall, blow-up a marble pillar or two, and they will fall to pieces.
- Fairy Companion: Marisa and Patchouli have a squadron of fairies to fight alongside them.
- Friendly Fireproof: Like in the Earth Defense Force games, your allies can't hurt you, but you can hurt them.
- Flying Saucer and Mook Maker: The Patchouli-esque spaceships and Star Patchouli.
- Girly Run: As menacing the robotic Patchoulis are, they run as girly as Patchouli.
- Heart Container: The Life-Up items (which looks like the 1-Ups from Mega Mari) can raise Marisa's HP by 2.
- Humiliation Conga: Marisa got it handed to by Patchouli (of all people), and she's not gonna take it lightly.
- Humongous Mecha: Marisa faces giant Patchouli-esque robots at several different points.
- Idiosyncratic Difficulty Levels: In DynaMarisa 3D, you have (from easiest to hellish) Easy, Normal, Hard, Lunatic, and Master.
- Infinity -1 Sword: The Metamorphosis Elixer, a weapon obtained after clearing all 26 stages on Master difficulty, lets the player dispense every weapon in storage. Sounds awesome at first, but once you get to very last weapon in holding, it'll be the only weapon to use for the remainder of the mission. This mean you'll need high-grade weapons to make good use of it and make sure to save best weapon for last. Even still, the weapon can be quite deadly.
- Infinity +1 Sword: Some of the bonus end-game weapons can qualify. Even certain high-level weapons with the right weapon modifiers can be this, too.
- Little Miss Badass, Token Mini-Moe: Remilia and Flandre, both cute vampire sisters packing heat with a sniper rifle and missile launcher respectively.
- Lost Technology: Patchouli admits to having used an ultra-energy object from the outside world to build the Star Patchouli. Unsurprisingly, it goes rogue.
- Macross Missile Massacre: Courtesy of enemy fairies equipped with ammo racks.
- Mission Control: Several visor-equipped fairies serve as this for Marisa.
- More Dakka: With assault rifles, shotguns, sniper rifles, rocket launchers, missile launchers, automated gun turrets, and grenades, Marisa Kirisame can never have enough dakka, ze!
- Nintendo Hard: Take the onslaught that Earth Defense Force provides, then you add some Touhou-levels of Bullet Hell and bring the level of sheer chaos up to eleven and you have this game.
- Not the Fall That Kills You…: Marisa can jump off a tower several stories above ground, and she can walk it off no problem upon landing.
- One-Man Army: While the fairies and the Mansion's residents may prove themselves useful, Marisa is ultimately the one who destroys any and all robots in her way. After taking on hordes of them in the penultimate mission, her Mission Control rightfully wonders if she's even human.
- Painfully Slow Projectile: Some of the Forbidden Launchers are very slow-moving balls of magical energy.
- Random Drops: Unlike the Earth Defense Force games, weapons dropped from enemies can have one or more weapon modifiers that can alter the statistic strengths of the gun and/or how the weapon behaves.
- Recurring Location: Seeing that same humongous foyer in the Scarlet Devil Mansion, that same giant dinning room, the same huge garden, the same underground basement area may cause some déjà vu.
- Redshirt Army: The fairy allies that accompany Marisa and the Patchouli Defense Force. On higher difficulties, Marisa's allies don't last long, but can still be handy for distracting enemies long enough for Marisa to thin them out.
- Say My Name: Marisa screams Patchouli's name when Patchouli performs her (off-screen) Heroic Sacrifice at the end of Stage 22.
- Sprite/Polygon Mix: As you'd guess by now, the game itself is 3D, but the items are entirely 2D sprites.
- The End... Or Is It?: The ending of the game reveals that the remains of Star Patchouli are active.
- Theme Naming: Each of the weapon types represents most of the characters of Touhou Koumakyou ~ the Embodiment of Scarlet Devil.
