Innocent Assault SS launches on Steam August 7, a 3D action adventure blending sword and gun combat across 35 maps, 32 enemy types and 37 defeat CGs

Mango Party has locked in a launch date for Innocent Assault SS, the 3D action-adventure title developed by ひみつ結社キジネコ. The game lands on Steam on August 7 with support for five languages, Traditional Chinese, Simplified Chinese, Japanese, English and Korean, plus full Japanese voice acting

The story casts a mysterious “demon” as the threat behind it all, a being powerful enough to swallow whole towns and their residents into a pocket dimension called the Magic Void. Demon hunters who go in after it never make it back out, which is exactly the path Eri is walking. She heads into the Magic Void chasing a dream of becoming a demon hunter, carrying little more than naive optimism and a fighting style built around switching freely between sword and gun

Sword and Gun, Swapped on the Fly

Combat in Innocent Assault SS revolves around two modes, sword and gun, and you can flip between them at any point mid-fight. Simple input combos on the sword side branch into different techniques, while the gun side lets you pick between different bullet types depending on how you want to clear a room. Both sides keep growing as your character grows, adding new sword techniques and new bullet varieties over time, so the build you end up with is genuinely your own

35 Maps to Pick Apart

Rich map design gives that combat system something to work with. Players can lean on the terrain itself to fight more safely and efficiently, reading a stage’s layout rather than just trading blows head on. The game backs that up with as many as 35 maps to explore, including 8 main-line stages, side challenges and dedicated boss encounters

Those maps are also built in layers, and that layered structure hides plenty of secrets for anyone willing to backtrack instead of rushing to the exit. It is that mix of terrain-driven combat and multi-layered stages that keeps exploration and fighting feeling connected across the run

Monster Girls, Traps and a Long List of Scenarios

The enemy roster leans hard into monster-girl and interspecies content. There are 32 enemy types in total, spanning regular monsters, traps and bosses, and a number of those monsters carry restraint-type adult skills. Get caught by one mid-battle and the scene plays out exactly the way genre fans expect

Beyond those in-battle restraint animations, rendered in 3D, the game adds as many as 37 defeat CG scenes, most of them starring non-human monsters and traps rather than human enemies. The scenarios on offer cover a wide spread, including restraint, tentacles, predation, vore, milking, absorption, breeding beds, status changes and aphrodisiacs

Dress Eri However You Like

A full costume system runs alongside all of that. Exploring the Magic Void turns up equipment of every kind, and you can swap weapons, skins and clothing across separate slots for the upper body, lower body, hands, legs, back and underwear

Some of that gear is tucked away inside the maps rather than handed to you outright, so there is a real reason to comb through every stage if you want Eri dressed exactly the way you picture her. A free 3D camera rounds the presentation out, letting you frame both exploration and combat however you want to look at it

Meet the Cast

Eri (CV: あきそら) is the protagonist, an innocent and energetic girl who throws herself into everything with real enthusiasm. Her cheerful, optimistic streak makes her easy to get along with, though she is also scatterbrained enough to cause plenty of trouble along the way. She trains hard because she is completely serious about becoming a demon hunter, even if almost everyone around her treats the idea as a joke

Nanami (CV: 夕宮奏風) is a mysterious girl who volunteers to help Eri on her journey, offering support from the sidelines while Eri does the actual fighting

Nyanko (CV: 岩石ゴンの丸) is a cat-people girl whose home Eri effectively requisitions as a base of operations. Somehow the two of them end up living together as a result

Kurie the demon (CV: 常盤はなこ) is the power at the center of it all, a being that appeared out of nowhere and swallowed part of the world. Every other living thing is a toy to Kurie, something to observe and play with day after day, and a lifetime of looking down on everyone else has left Kurie with an extremely arrogant personality
