Feminization Device

Feminization Device is a classic adult game where players take on the role of a unique male Kyokai in a futuristic world, battling various monsters. Utilizing agile movements and accurate shooting prediction, players can easily eliminate enemies and protect the city. During this time, players will also need to strategically deploy different types of Kyokai to form a powerful team to deal with various monsters, building deep emotional bonds with them in battle and unlocking corresponding H-scenes. Fans of adult games shouldn't miss Feminization Device!

Battle System:

The game uses an over-the-shoulder shooting perspective, and players can switch between combat mode and movement mode by clicking the right mouse button.In movement mode, use the arrow keys to move and press the spacebar to sprint. Sprinting consumes stamina.

On the map screen, players can move from their current region to an adjacent one. The buttons on the right display the adjacent regions, with colors indicating the threat level. The left-side buttons allow you to revisit your current region. The "City" button opens an overview of the entire map.Once in an area, players can exit through the designated exit to return to the map screen and move to the next region. This process repeats, allowing for exploration across multiple regions.Entering the map screen, players can move from the current area to adjacent areas. The right column of buttons represents options for adjacent areas, and the enemy situation in each area is also indicated by color. The left buttons allow you to re-enter the original area. Pressing "City" displays the entire map.The goal of the Battle Maiden Association is to completely eradicate all demonic creatures in the city. The game is won when all areas are green zones. Conversely, the game is lost when all areas become red zones.

Green Zone: A safe area confirmed to be free of enemies.

White Zone: An unknown area where demonic creatures are lurking, requiring cleanup.

Yellow Zone: A conflict area controlled by gangs or invaded by demonic creatures, possibly with security forces depending on the location.

Red Zone: Completely dominated by demonic creatures, with tentacle monsters continuing to invade adjacent areas.

Characters are divided into three types: melee, shooter, and special abilities. Each character has different charged attacks; some can set traps or barriers, while others can unleash high-damage long-range attacks.

Features:

Dynamic Territories: Transition between four critical zones—safeguard Green Zones, investigate mysterious White Zones, battle faction conflicts in Yellow Zones, or confront apocalyptic Red Zones teeming with monsters.

Strategic Expansion: Conquer areas by completing missions that weaken demonic influence, with progressing control reshaping the map’s safety and accessibility.

Rising Stakes: Failure to secure zones risks escalation—the longer demonic forces dominate, the faster adjacent regions turn crimson, threatening humanity’s collapse.

Precision Matters: In civilian-heavy Green Zones, accidentally harming innocents triggers law enforcement, forcing stealth adjustments.

Alliance Systems: Yellow Zones occasionally ally players with police or faction allies, but Red Zones force solo survival against overwhelming odds.

Objective Variety: Destroy portals and supplies in assault missions, eliminate marked elites to face zone-specific bosses, or rescue hostages in timed rescues—each with escalating and environmental hazards.

Changelog:

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!

Player Comments:

For being a one man passion project... it's ok, an improvement over prior entries in some ways but somehow in the shadow of the creators original 2d title. Unfortunately the creator seems to have left this in a permanent state of being an unfinished buggy entry since forming a team to create their next entry. I've logged more time in this game than AC Shadows so I can't rate it any lower.

I'm a bit conflicted on this one. It's at the same time incredible and terrible.If you are in a trap and tentacles/rape mood, this game delivers. It has some weird mix of 3d with 2d added in with some jank that makes it look both hilarious and incredible. Pair that with the voice lines and you have something that will keep you entertained. If you miss any, the game unlocks all of them for you once you get one of the endings.You just go around completing missions depending on a given area color then go to another adjacent area with the same or different color until you get an ending. Some of the objective types are way too easy, particularly the one to free girls.Also, for a what's similar to a dungeon crawler game, it has virtually no area variation or upgrades. You'll deal the same damage from start to finish, will take the same damage from start to finish, defeat the same enemies in every area, find the same traps, the same objectives... it's too short to become a problem, but it gets old fast enough that I wouldn't stomach unlocking every ending.

very good game, animations are top notch and the ideas behind them are very hot. only thing that will improve this game is adding even more enemies that you can lose to. maybe voice acting for the cutscenes, but honestly not rly necessary since this game likes to keep it simple. 10/10 overall, honestly surprised me because i had WAY lower expectations of this game.

Final Verdict:

As a warrior princess affiliated with the association, you patrol the city day and night, defeating demonic creatures that are lurking or attacking.Conquer the crimson-stained "Red Zones" and transform them into Green Zones to expand humanity's safe territories. Complete strategic missions such as rescue missions, extermination missions, purging missions, and special assault missions. Uncover the truth behind the demonic invasion, track the harsh fate of the battle maidens, and expose the presence of traitors.
