nanoBreach Quantum

[Image] nanoBreach Quantum is a fast roguelite shooter for s&box by Nanophage Research, played solo, in co-op, head to head or with bots. Fight through generated laboratory floors or hold a sealed arena against endless waves, level up with XP Molecules, and build every run from guns that mod and evolve, stacking upgrades and strange mutations — all in limited-ink pixel art, over a dark ambient soundtrack. [Image] • Campaign — Solo or in co-op with up to four players. Nine rounds that build to the Director on round nine. Every level-up pauses the fight for a free pick from three loot cards. Win and keep going into endless rounds with the same build, and unlock the next of ten Breach Levels, each harder than the last and worth more score. • Survival — Solo or in co-op with up to four players. One arena, four gates, waves that never stop. Hostiles stream in through the gates, with a boss every eighth wave; clear a wave and the next arrives after a short breather, with no clear screen and no new floor. Loot comes from leveling up, as in the Campaign. • Versus — A free-for-all for up to four players on a courtyard arena of its own. Everyone starts with the pistol; the other nine guns are pickups around the map, with the heaviest in the gate alcoves. First to 15 frags, or the most after five minutes, wins. • Daily Breach — One Campaign seed a day, the same for everyone, with no research and the standard loadout, and one attempt to make it count. Your score goes on the day's own leaderboard; a new Daily starts every midnight UTC. • Play with Bots — Fill Versus, a co-op Campaign or co-op Survival with one to three bots, on Easy, Normal or Hard, and play offline. Bots fight, dodge, grab guns, take their own loot and revive you. A host can add them to an online lobby too. Campaign floors are seeded: nine rooms with side bays, looping corridors and a minimap that expands into a tactical map. The Survival arena is the same open octagonal hall every run, in Nanophage black and teal with green hostiles. Retry This Seed replays the same layout, New Run rolls a new one, Play a Seed starts any seed you type and Copy Seed shares yours. [Image] Ten guns, from the Molecule Pistol's unlimited reserve to chain lightning, piercing rails and freezing fans, each with its own shape and muzzle flash: a needle SMG with a glass vial magazine, twin phase rails, a rotary flechette cluster, a shoulder launcher, a frost sprayer and more. Guns you own come back as mods: Mk II and Mk III add ricochets, burning pellets, seeking rockets, stuns, shrapnel and more. Hold a Mk III gun's paired upgrade and it evolves into something new: the Singularity Pistol, Breach Cannon, Needle Storm, Pulse Lance, Annihilator, Solar Repeater, Payload Cascade, Storm Conductor, Flechette Tempest or Absolute Zero. Reward cards show the real DPS, ammo and health change before you commit. Ammo is scarce, so every magazine counts. [Image] Sixteen enemy types swarm, spit, shield and charge. Four of them each ask for something different: • The Volatile Blister bursts when it reaches you. • The Mitotic Cell splits in two when it dies. • The Phage Lens snipes along a red sightline you have to step off. • The Symbiont Mender keeps the pack healed until you deal with it. Every wind-up and every cry has its own sound, so you can hear an attack coming from behind, and hostiles find their way around walls instead of piling up against them. Each dies its own way, too: flesh bleeds out into a heap, insects splay, machines collapse in sparks and scrap, and viruses swell and burst. Bosses are rare, and they fight in phases. One arrives every eighth Survival wave: the Colossus, Hive Virus, Overseer, Helix Warden, Apex or Patient Zero. At each phase it staggers, slams the floor and adds new moves: chained charges, shockwave slams, spiral barrages, blinks, spore mines and escorts that shield it. On round nine of the Campaign the Director takes over. At two thirds of its health it opens containment, releases one of the six and hides behind a shield until that boss falls. Below a third it melts down and vents reactor shockwaves you have to jump or dash through. Endless rounds bring them all back tougher. [Image] • XP Molecules level you up during a run. Every level adds weapon damage, maximum health, fire rate and movement speed. • 12 run upgrades stack for the rest of the run; the two rare ones turn up less often. • 12 mutations change how a run plays: kills that detonate, a freezing dash, a guaranteed critical hit every fifth shot, a reload that sends out a shockwave, a field that heals the whole team, and more. • Nanophage samples drop from bosses and rare kills and are banked the moment you collect them, even if you die. Spend them on 6 permanent research tracks, including Adaptive Choice for free rerolls, on new mutation cards for your loot pool, and on 6 starting strains, each with its own gun or mutations. [Image] • Five leaderboards — Campaign rounds, Survival waves, today's Daily Breach, the fastest Campaign victory and the highest Breach Level won — each with a friends filter • Co-op for up to four players in the Campaign or Survival: the host gathers everyone in a lobby and starts when ready, the team levels together, everyone picks their own loot, and downed teammates get back up when someone holds E beside them • Multiplayer chat and standings for every player: kills, boss kills, damage, downs and score in co-op, frags and deaths in Versus • A Codex of 30 research files on every hostile and on what happened to the facility • 19 achievements, up to winning the Campaign while firing only the starting pistol [Image] W A S D — Move Mouse — Aim Left click — Fire R — Reload Shift — Dash (briefly blocks damage) Space — Jump Mouse wheel / 1–0 — Switch weapons E (hold) — Revive a downed teammate F — Continue after a Campaign clear T — Chat in multiplayer; hold Q for the standings Tab — Tactical map P / Esc — Pause M — Mute W / S or arrows, Enter or Space — Move through menus and confirm, or point and click Controllers are fully supported, menus included: sticks to move and aim, triggers to fire and dash, with aim assist and rumble.
