Hacker Cat: Idle Action RPG

The hacker cat
fights on its own

NyanCode, a hacker cat, moves through the arena taking out enemies automatically while you pick items from the supply shop between stages. When a run ends you return to the lobby to manage permanent upgrades, the archive and the Quantum Lab. Reach the level cap and Ascension opens a new form and a higher difficulty tier.

How a session runs

Lobby ─▶ Map select ─▶ Battle ─▶ Supply shop ─▶ Battle ─▶ … ─▶ Results ─▶ Lobby
 ├─ Workshop (6 permanent upgrades)
 ├─ Quantum Lab (ascension · 8 Q-Bit traits)
 ├─ Archive (collection) · Skins · Mailbox
 └─ NyanNet ranking / Settings

One sortie is called a run. The bits and items you gather disappear when the run ends; gold and archive entries, your level and your ascension stay with you.

How it plays

Runs without you

Leave the controls alone and the movement AI dodges bullets, keeps its distance, and fights. Grab the joystick whenever you want to take over.

A different build every run

Clear a stage and pick from the supply shop. Reroll the slots to chase the combination you want.

Time away still counts

Idle rewards accumulate while you are away — four hours by default, up to twelve once you level the Background Daemon in the Quantum Lab.

Stop and pick it up later

Close the app mid-run and the next launch offers to continue or cash out.

1.4.0 UPDATE

Ascension — hit the cap, be reborn

Reach level 250 and clear Sector 10 on your current difficulty to ascend. Gold and workshop upgrades reset, but your level, archive and sector records stay, and you receive a new form, the next difficulty tier and Q-Bits, the Quantum Lab currency. Daily level gains are capped, so the final form is a journey of roughly two months.

Three form evolutions

NyanCode changes shape with every ascension: Overclock (I) → Chaos Kernel (II) → Quantum Singularity (III). Each form adds +10% / +25% / +45% to combat stats and raises the level cap to 500 / 750 / 1,000.

Four difficulty tiers

Normal → Hard (enemy HP ×3, damage ×2) → Hell (×10, ×5) → Quantum Singularity (×30, ×10, endless only). Each ascension unlocks the next tier, and every tier pays Q-Bits for first clears.

Quantum Lab

Spend Q-Bits on eight permanent traits: Quantum Compute Core, Nano Energy Shield, Data Compression, Background Daemon, Data Backup, Overclock Booster, Gold Amplifier and Quantum Support Drone.

Ascension ranking and achievements

The NyanNet Top 100 ranks by ascensions, then tier progress, level and power, with an ascension badge and form colour beside each name. Tap a row for the profile; achievements and leaderboards also go to Google Play Games.
