About
A 2016 hack-and-slash brawler Teenage Mutant Ninja Turtles: Mutants in Manhattan, developed by PlatinumGames (Bayonetta, Metal Gear Rising) and published by Activision, starring Leonardo, Donatello, Raphael and Michelangelo across nine stages of fast, combo-driven combat against classic TMNT villains. Players control one turtle and swap between all four mid-fight, with the others AI-controlled offline or human-controlled in four-player online co-op.
It drew mixed-to-unfavorable reviews for repetitive mission and level design and the absence of local co-op. The game was pulled from all digital storefronts on January 3, 2017, less than eight months after launch, when the TMNT license expired, leaving it unavailable for sale.

⚙ Setup notes
Game: 2016 PlatinumGames / Activision hack-and-slash (Steam appid 338400).
Supply your own copy: Removed from sale in Jan 2017 (~8 months after launch) when the TMNT license lapsed — bring your own copy.
DRM: Uses Steam DRM only (no GFWL / Denuvo / SecuROM), so it runs under Proton with no DRM workaround.
Proton: GE-Proton is the safe pick; stock proton_experimental also reported working.
Controller: Native controller support — gamepad works out of the box, no Steam Input layout needed.
Display: Community reports confirm playable 60fps gameplay on the Deck. Note: the PC build is hard-locked to 30fps by default. A community 60fps unlock (jackfuste's Cheat Engine trainer, run alongside TMNT_MiM.exe) is the known fix if you want uncapped framerate — optional, no links.
Exe: Launch executable confirmed as TMNT_MiM.exe (the Steam process display name is the full game title).
The one thing to know
Supply your own copy: Delisted (lapsed TMNT license) — supply your own copy; configuration only, no links.
DRM: Steam DRM only — no GFWL/DRM workaround needed.
Controller: Native gamepad support, no Steam Input layout required.
Display: Default 30fps hard cap on PC; optional community 60fps unlock (jackfuste Cheat Engine trainer) if desired.

Get the artwork
deckport never hosts game images. Open this game on SteamGridDB, pick
the cover / hero / logo / icon you like, and drop them into the
game folder under .deckport-art/ before you push it to the
Deck. The importer files them under the right names automatically.
Run it on your Deck
Two files: the one-time importer (deckport.py) in your
Deck's home folder, and this game's install helper. Copy the game
into ~/Games and run the helper with Steam closed — it
writes the recipe (binary, launch options, Proton version)
and registers the shortcut with artwork.
