DynaMarisa 3D is doujinThird-Person Shooter game by Twilight Frontier. It stars Marisa Kirisame and doing what she does best: blowing stuff up. DynaMarisa 3D is essentially TouhoumeetsEarth 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:
Action Girl: Marisa. Sakuya, Remilia and Flandre, and even Patchouli also take part in turning Mecha-Mooks into wrecks.
Humongous Mecha: Marisa faces giant Patchouli-esque robots at one point of the game.
Infinity+1 Gun: Some of the bonus end-game weapons can qualify. Even certain high-level weapons with the right weapon modifiers can be this, too.
Infinity-1 Gun: The Metamorphosis Elixer, a weapon obtained after clearing all 26 stages on Master difficulty, let's the player dispense every weapon in storage. Sounds awesome at first, the 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.
