Cyber Security

What Cyber Security is

Cyber Security is a free-to-play cyberpunk roguelike with an action RPG core, published and developed by Naughty Nation and hosted on Nutaku. The player takes the role of a female cyber-police officer in a neon-lit megacity of the future. Runs are fast, procedurally generated and mostly automatic, and between runs the game turns to a private chat with the officer's girlfriends, which is where its adult content lives. Nutaku lists it for Android, iOS, PC browser and mobile browser, and marks it as free, with a note that free games may include in-game purchases.

Nutaku files it under the genres Action Adventure, Action RPG and Roguelike, and tags it Idle, Auto Battle, Harem and Female Protagonist. A reader who stops here should know the shape of it: a short-session mobile-friendly action game with a flirting and collecting layer on top.

How it plays

The premise, as the page tells it, is a bold female cyber-police officer enforcing the law by day in a megacity full of rogue AIs, corporate drones and digital threats. Each run drops her into a procedurally generated level of those enemies. The controls come down to one idea. Move to dodge the lethal laser barrages and hacking attacks, and when you stand still the officer automatically fires her high-tech arsenal. The page puts it as move or shoot, with timing as everything, and it names its model outright: the key features call the game a cyberpunk roguelike like Archero. That makes it an auto-battle design in which the player's job is positioning, not aiming.

Progress carries across runs. You collect upgrades, gather gadgets and abilities, upgrade weapons and strengthen the officer so she survives longer and pushes deeper into what the page calls the cyber underworld. The key features list hundreds of ability combinations, tough AI bosses and a depth of progression and collection. The page describes the levels as built for endless replayability, which is the developer's claim about how the randomization holds up over many runs.

There is also an idle side. The page says the game has auto battle and idle elements and is built for mobile, with short intense sessions or passive progress when you are away. So it can be played actively for a few minutes or left to make passive progress while the player is away, and a later feature line repeats the point as quick bursts of action anytime, anywhere.

The second loop is the chat. In her private encrypted chat the officer connects with girlfriends, described as daring cyber beauties from all corners of the net. Each girl has her own personality and backstory, according to the key features. The conversations run from light flirting to steamier exchanges, and the girlfriends send photos that grow more provocative as the chat goes on. Every successful run brings new messages, new animations and a growing collection of images, so the combat loop is what pays for the relationship loop. The collection is explicitly part of the design: the page talks about building a gallery of intimate photos from your virtual girlfriends and a collection of gadgets and weapons alongside it.

The structure is a repeat cycle rather than a story with chapters. The page gives no count of girlfriends or levels. What it does state is the loop: run, upgrade, return to the chat, open more, run again, with the page's own tagline of enforcing the law by day and courting the neon city by night.

Content and themes

Naughty Nation's description makes the adult side a reward system. What successful runs pay out includes exclusive adult content with nudity, big breasts and animated sex elements. The tag list carries Animated Sex, Big Breasts, Nudity, Harem, Collection and Female Protagonist, and the page ties the harem theme to a strong female lead surrounded by attractive girls with various sexual preferences. It states that chats and scenes include Female plus Male and Male plus Male scenarios, so the content is not limited to one pairing.

The adult material is delivered as chat messages, photos and animations, and it is styled to the cyberpunk setting, with neon and cybernetic motifs carried into the photos. The page tags the game 3D and describes its look as neon lights, futuristic police interfaces, character models and fluid combat, all in 3D. The tag list also includes Cute, Fantasy, Dungeon Crawler and Exploration, while the premise text itself is science fiction: a megacity of the future, rogue AIs, corporate drones and a police force with high-tech weapons.

Platforms and where to get it

Under its Available On heading Cyber Security shows Android, iOS, PC Browser and Mobile Browser. The page carries buttons to play free now, to download the Android app as an APK file and to install on an iOS device as an IPA file, and the tag list includes Includes Android App and Mobile Friendly. All of that sits on the Nutaku page itself, which is the official place to get the game. Nutaku is the only store the page names.

The browser entries cover desktop and phone, which fits a game its developer calls perfect for mobile and built for short sessions. The Android and iOS routes go through the app files offered on the Nutaku page. It lists these languages in its game information: German, Russian, Portuguese (Brazilian), Japanese, Portuguese, English, Chinese (Simplified), French, Spanish and Turkish.

Price and model

The model is free to play. Nutaku marks the game as free and adds that free games may include in-game purchases. No price for such a purchase appears on the page. What it describes instead is what play itself earns: upgrades, rare gadgets and abilities from runs, and messages, animations and photos for the chat as rewards for successful ones, with passive progress on top through the idle elements.

Development state and version

The page does not state a version number or a development state. What its game information block holds in October 2026 is the language list, and above it the single name Naughty Nation as both publisher and developer. The feature list speaks of growing photo collections and of content opening up with successful runs, which describes how a player's own game expands and says nothing either way about future updates.

Who it suits and who it does not

Cyber Security suits a player who wants a free action game for a phone or a browser tab, with runs short enough for a few minutes at a time and passive progress for the time spent away. It also suits someone who likes collecting and upgrading and wants a female-protagonist harem premise in a cyberpunk setting, with 3D visuals and animated scenes as the reward for progress.

The caveats are about fit. Purchases are part of a free-to-play game, and the amount of content is something the page describes in words like hundreds of ability combinations and not in levels or chapters. The gameplay is built on auto-fire and repeated procedurally generated runs, so someone looking for a long authored story, a turn-based battle system or a game of decisions will find a different kind of game. Nutaku is the only place the page names for playing it.
