Lust//Protocol is an 18+ third-person action hack-and-slash made with Unity by Lustborn Studio, using animated 3D art in a dark cyberpunk setting. You play V-13, a rogue bio-weapon that corrupts enemies during fights and converts them into power. Fights mix stylish combos, aerial launches, ground slams, lewd finishers, and explicit weapon QTE attacks, blending adult content with the core loop. The game centers on corruption, female domination, and sci-fi themes.
The current build is v0.1.0, released October 14, 2026, and development is ongoing. It is available on Windows in English and is uncensored. This update adds the mini boss Stinger, a mechanical scorpion that challenges V-13 with charges, restraint moves, energy draining, and summoned enemies. Its drain pounce traps V-13 in a restraint interaction where she must escape through a mini game while losing HP. Another hold pounce restrains her but lets allies attack instead, and a rush attack snaps its pincers.
Developer's description
Lust//Protocol is an 18+ third-person hack-and-slash action game set in a dark cyberpunk world where stylish combat and explicit adult mechanics are deeply integrated into gameplay.
Take control of V-13, a rogue bio-weapon capable of corrupting enemies through combat and turning them into a source of power. Launch enemies into the air, knock them to the ground, chain weapon combos together, perform lewd finishers, and unleash explicit weapon QTE attacks as you dominate your opponents.
v0.1.0
NEW BOSSES
Mini Boss, Stinger
Meet
Stinger
, a mechanical scorpion mini boss designed to challenge V-13 with more than conventional attacks.
Stinger can charge toward V-13, restrain her, drain her energy, and summon additional enemies to complicate the encounter.
- Drain Pounce
Stinger launches toward V-13 and captures her in a restraint interaction. While trapped, she must fight to escape through a mini game while Stinger drains her HP.
- Hold Pounce
Instead of draining V-13 directly, Stinger restrains her and leaves her vulnerable to attacks from other enemies.
This becomes particularly dangerous when Stinger has summoned allies to fight alongside it.
- Rush Attack
Stinger charges directly toward V-13 while snapping its massive pincers.
- Restraint Escape Mini Game
When restrained, V-13 must continuously tap
F
to fill the escape meter and break free.
This system supports enemy grabs, restraints, and other interactive encounters.
- Enemy Summoning
Stinger can summon additional enemies during the fight. If V-13 gets restrained while these enemies are still active, they can continue attacking her while she struggles to escape.
You'll need to escape quickly and manage the surrounding threats to avoid being overwhelmed.
The core encounter mechanics are functional, while the restraint and drain interactions currently use static placeholder poses. Their dedicated animations will be added in a future update.
The Final Boss
Waiting at the end of the level is the main boss, featuring three distinct attack sequences, functional damage mechanics, grapples, and a defeat sequence.
The final boss's combat, attacks, grapples, and defeat mechanics are now fully functional.
- Attack 1, Laser Sweep into Tentacle Stab
The boss sweeps a laser forward before following up with a tentacle stab.
- Attack 2, Chasing Spin into Horizontal Laser
A spinning tentacle attack chases V-13, followed by a horizontal laser sweep.
- Attack 3, Three-Hit Tentacle Combo
The boss performs a three-hit combo, attempting to grab V-13 with each swipe.
These attacks now have functional gameplay effects, rather than being limited to attack animations.
- The Boss Can Summon Allies
The final boss can summon additional enemies to assist it during combat.
During the encounter, the boss can restrain one of its summoned allies and drain them. This creates another layer of pressure: defeat the summoned enemies quickly or interrupt the boss while it is draining one of its allies.
- Boss Grapple and Drain Animation
The boss's grapple mechanics are functional, but the dedicated animation for draining V-13 during a grapple is still pending.
For now, this interaction uses a
static placeholder pose
. The final drain animation will be added in a future update.
- Boss Defeat and Ending Cutscene
The final boss can take damage and be defeated, and the game now includes an
ending cutscene
to conclude V-13's first mission.
After defeating the boss, players can also perform the drain interaction. However, the animation for V-13 draining the defeated boss currently uses a
static placeholder pose
.
Both drain animations are planned for future updates. The boss encounter, defeat mechanics, and ending cutscene are already in place.
LEWD ENCOUNTERS & ANIMATION PROGRESS
This update also brings significant progress on the game's lewd encounter systems. Each major interaction now has its own dedicated animation or static pose, establishing the foundation for the remaining lewd content.
- Ranged Female Enemy
The ranged female enemy now has
separate animations for her QTE and parry sequences
, giving each interaction its own presentation.
Her finisher currently uses a static pose, with a dedicated animation planned for a future update.
- Stinger Mini Boss
Stinger's finisher and grapple interactions now have static poses in place. The underlying gameplay mechanics are functional, and the remaining work is focused on creating dedicated animations for these interactions.
- Final Boss
The final boss also has static poses for its grapple and finisher interactions. Its combat, grapples, defeat mechanics, and ending sequence are already functional.
The remaining animation work includes the boss draining V-13 during a grapple and V-13 draining the defeated boss after the fight.
What's Next for Lewd Content?
The current poses are placeholders while the dedicated animations are being produced. With the core gameplay systems now in place, development can increasingly focus on bringing these interactions to life through finished animations and improved presentation.
UPDATED MECHANICS
Three Types of Enemy Attacks
Enemy attacks now have different effects on V-13, making combat encounters more varied and challenging.
Damage Attacks:
Deal damage to V-13's HP.
Interrupt Attacks:
Interrupt her current action and briefly stun her.
Knockdown Attacks:
Knock V-13 to the ground, temporarily taking control away from the player.
These different attack types make positioning, timing, and reacting to enemies more important during combat.
Player-Controlled Finisher Camera
The main finisher animation now features a fully player-controlled camera instead of a pre-animated camera sequence.
You can adjust the view throughout the finisher to find the angle you prefer.
Move the mouse
to rotate the camera around V-13.
Scroll the mouse wheel
to zoom in and out.
You're no longer locked to a predetermined camera angle, giving you much more control over how you view the finisher.
