About this game

A portal opens at the end of the room. On the other side it is always another realm, always another room full of creatures, and your build is still to be assembled.

Sundergate is a 3D roguelite FPS built for phones. Every run starts from scratch: you go down floor by floor, pick one upgrade between each of them, and get as far as you can before you fall.

MOVEMENT COMES FIRST
Double jump, air dash, crouch slide and five guns with their own weight. Moving well is what separates floor 5 from floor 15.

CONTROLS MADE FOR A THUMB
Floating stick on the left half, drag to aim on the right, a big FIRE under your right thumb and the five actions in an arc around it. Everything mirrors for left-handed play, with adjustable button size and tunable aim sensitivity.

A DIFFERENT BUILD EVERY RUN
At every portal, three cards: damage, fire rate, health, speed, extra jump, ammo, quick dash, vampirism. They stack, and today's run is not yesterday's.

WHAT IS COMING FOR YOU
Seven kinds of monster, from the slow blob to the brute that charges. Shooters that keep their distance, flyers that never land, and a BOSS every five floors, with its own health bar and a volley that forces you to dodge.

FIVE REALMS
Fractured Meadow, Amber Sands, Violet Void, Frozen Ridge and Crimson Forge. Bright, colourful low-poly, not one more brown and dark shooter.

COINS ARE NEVER LOST
Dying is part of it. The coins you gathered go to the bank and become PERMANENT upgrades: vitality, firepower, bandolier, thruster, barrier, greed, second chance, and a companion that fights at your side forever.

NO CATCH
No ads, of any kind. No in-app purchases, at any price. No sign-up, no login, no account. The app asks for a single device permission, vibration, and it collects and sends nothing: your progress stays on your phone.

Plays 100% offline, from the first tap to the last.

FOUR DIFFICULTIES
From Easy to Nightmare, changing monster health and damage.

Six languages: English, Portuguese, Spanish, German, French and Italian.

Rating: stylised violence, no realistic blood.
3D roguelite FPS with portals and builds. No ads, no purchases, offline.

What’s new

The game now has an opening screen, where RNG Desenvolvimento signs before the menu. It was the only game in the studio that went straight to the menu, without saying whose it is.
