Description

Redline Protocol, the latest release from PotatoeStudio, drops you into a neon-soaked cyberpunk future where every battle is fought from the side, one line at a time. You assemble a five-woman squad through an in-game gacha that never asks for real money, then kit them out and hold your position as enemy waves press in from the right. With five distinct classes—Tank, Bruiser, Sniper, Artillery, and Support—each fighter brings her own auto-attack style and a tap-to-trigger special, so how you assemble and position your team matters every bit as much as raw stats. This 2D game blends tactical combat with a cast worth fighting for.

Between battles, Redline Protocol shifts focus to the relationships you build. Gifts and affection raise your standing with each character, unlocking gallery events, narrative scenes, and 2DCG art—including AI CG—that open up only as you get to know her better. Push a favorite’s affection far enough and the story turns explicit, with scenes that lean into anal sex, BDSM, and creampies for players who want that side of the catalog. Big-ass character designs and sharp 2D art keep every recruit memorable, both on the defensive line and off it.

The loop rewards tactical thinking as much as the time you invest in the women fighting beside you. Position your squad, trigger specials at the right moment, and watch enemy waves break against your line—then spend the spoils on gifts and deepen the bonds that unlock the gallery. It’s a combat game with real stakes and a relationship system with real payoff, built for players who want both.

Redline Protocol is in active development at version 0.3, and PotatoeStudio keeps expanding the roster, scenes, and systems with each update. Download Redline Protocol now and start building your squad today.
