About this game

GEM CITY — a city shrouded in smoke, rain and the glow of neon lights.
Somewhere between the skyscrapers and the clouds, someone declared
a brutal war on detectives.

Play as ZERO or SIN — two detectives, pilots of armored fighter craft. Only you know
what truly lurks behind the waves of hostile machines attacking Gem City.

── UNIQUE MECHANICS ──
Don't just shoot — collect! GEM CITY NOIR fuses dynamic arcade shoot 'em up
action with gem collection mechanics inspired by match-3 games. Destroy an
enemy, release a gem and grab it before it disappears. Every grab builds a
combo, and every combo gives you a ruthless edge on the battlefield.

── TWO SHIPS, TWO STYLES ──
- Helleborus XG-1 (ZERO) — surgical precision and incredible speed.
- Delphinus EA-1 (SIN) — devastating power and impressive range.

Each ship demands a completely different tactic. Each offers its own
dialogue, unique story and separate achievements to unlock. This isn't
the same game twice — it's two different adventures in one!

── EPIC BOSS BATTLES ──
- OCULUS NOCTIS
- ZEPPELIN MORTIS
- and . . .

Every boss is a multi-stage battle, a unique fighting style and a new
mystery to uncover. Behind all the chaos stands the enigmatic X —
and only you can stop them.

── TIME ATTACK MODE ──
Four special timed operations. Global leaderboards, fast action and
maximum chaos in minimum time. Show the world who really rules the skies.

── OPERATIONS BASE ──
Develop your arsenal between missions. Invest gems earned in battle
into ship upgrades and build your edge before the next confrontation.

── NOIR TO THE BONE ──
- Fully bilingual — play in Polish or English (PL / EN).
- Atmospheric presentation — original soundtrack and a gritty,
hard-boiled noir vibe.
- Pure gameplay — ZERO ads, ZERO microtransactions, ZERO compromises.

Gem City is waiting. The rain won't stop.
It's time to all STG fans take matters into your own hands!
Noir shmup with match-3 gem mechanics. Shoot, grapple, survive.
