Overview
Feminization Device is a 2D action adult game for players who want dark corruption fantasy mixed with combat. The tone is grim and explicit, built around loss of control rather than romance.
Story
A Battle Maiden works for an association tasked with hunting demonic creatures that hide in or attack the city. Her nightly patrols put her directly in the path of monsters whose attacks threaten more than her life.
Gameplay
Players fight through city patrols in shooter-style combat against monster enemies, with encounters that can turn into corruption or transformation events depending on outcome. Losing fights or failing defenses opens into bondage and forced-encounter scenes tied to the game's transformation and gender-bender themes. Progress branches toward multiple endings based on how battles and encounters are resolved, with pregnancy and slave-status outcomes among the possible paths. Item pickups found during patrols add passive or activated effects that shift how fights and encounters play out.
Features
- 2D animated art with monster and tentacle-themed enemy designs
- Combat-driven structure where failure leads into corruption scenes rather than a simple game over
- Multiple distinct endings shaped by transformation and slave-route outcomes
- Item system with both manually triggered and automatically triggered effects
Notes
Content includes non-consent, graphic violence, and forced transformation themes; players sensitive to rape or gender-bender material should be aware before starting.
Installation
1. Extract and run.
Changelog
v0.6
- New Items Added
- Because the warehouse looked too empty! Version 0.6 has added some new items! In addition to the basic four items that are activated by pressing a button, three automatically triggered items have been added! These items will trigger on their own under certain conditions based on probability~
- (Actually, the font in the warehouse has been adjusted as well)
- 【Anti-Magic Shield】
- Anti-Magic Shield: Automatically triggers with a 2/3 chance when touching tentacles, infectors, or lust toxin nematodes, repelling the demonic creatures touched. Does it look familiar? Yes~❤ This is actually...
- turned into an item!
- When you first saw this 【Feminization Device Icon】, it might have been unclear what it meant. It triggers with a certain probability when touching roadside tentacles. This was because when initially conceiving the 【Tentacle-infested Red Zone】, I realized that if we really placed so many tentacles in the scene, players would be entangled by tentacles every few steps! That would greatly diminish the experience. Thus, a mechanism was set up where 【if you touch a tentacle, there's a 1/3 chance of being entangled by the tentacle, and a 2/3 chance that the feminization device icon pops up】, allowing the scene to be filled with tentacles while still letting players pass through~ This is actually a port that will be transformed into an item in a future update~
- 【Electric Shock Patch】
- Electric Shock Patch: Automatically triggers when touching tentacles, infectors, or lust toxin nematodes (prioritizes activation over the Anti-Magic Shield), repelling the demonic creatures touched. Each time the player arrives at a new scene, the shop refreshes items~ Wanting to increase the chances for players to get items that 【prevent entanglement by tentacles】, another functionally similar item was added~ However, the Electric Shock Patch triggers 100% of the time~ Be careful if you want to see the CG of being entangled by tentacles~❤
- 【Lust Toxin Suppressant】
- Lust Toxin Suppressant: Automatically triggers when lust level is full (does not trigger when wearing a feminization latex suit), forcing the lust level to reset to zero.
- When players navigate through the Red Zone, they might often have to stop due to a full lust level~❤ If you have the Lust Toxin Suppressant, there's a 100% chance that the lust level will be forced back to zero~ Be cautious if you want to see the masturbation CG~❤
- Demonic Transformation
- After players complete the game, the hidden characters they unlock are two female demons: Maris and the Succubus. Compared to other characters, these two female demons possess the ability to transform into their demonic forms. The biggest advantage of demonic transformation is rapid health regeneration, along with a certain chance of having vampiric abilities (according to the setting, demons have the ability to regenerate automatically, and can self-repair severed limbs via tentacles). Maris's basic attack involves throwing lust toxin bombs at long range (similar to the attack of a typical female demon mini-boss), but after transforming into her demonic form, Maris switches to melee combat, sprouting whip-like tentacles from her arms for attacks, which include vampiric abilities~
- The Succubus, already equipped with a vampiric sword, inherently possesses melee vampiric abilities. However, after transformation, her vampiric abilities disappear, and her melee attack shifts to long-range (similar to Maris's throwing of lust toxin bombs), and as a charge-up type character, she can now charge up both melee and long-range attacks.
- Added a 1-second cooldown to Felicia and Maris's charged attacks, similar to melee
- Previously, there was a bug where if players used Felicia and Maris to lay mines and then quickly attacked with the left mouse button, they would enter a "rapid attack state." It seems the cooldown system used for laying mines, similar to an item slot, did not affect the melee cooldown system. Laila seems not to be affected by this, possibly because she only needs to charge for more than 0.2 seconds to lay paralysis traps, while Felicia and Maris require about 1 second of charging? In any case, now these characters also have a 1-second cooldown after laying mines, which should have resolved this bug…
- Players Can Pass Through Teammates
- This might have been overlooked previously.
- Felicia's Charge Skill Description Update
- After version 0.4, Felicia's charge skills were modified... but the descriptions on the store page and the character selection screen were not updated. These have also been updated in version 0.6!
- Bunny Girl/Heavy Handgun UI Update
- Previously, I didn't realize that the heavy handgun button was slightly larger, but this has also been updated in version 0.6!
- In-Game Mouse Change
- When you start the PC version of the game, you should notice that the mouse cursor has changed!
