About this game
WE WHO ARE ABOUT TO DIE SALUTE YOU!
Enter the DOME, a fast paced, retro roguelike FPS with movement shooter mechanics. The DOME is ready for your BLOOD - Prepare to rip and tear your way through the arena. You're not here to survive. You're here to become a LEGEND.
BECOME AN UNSTOPPABLE GLADIATOR OF DESTRUCTION
Strap into DIESELDOME - a Roman-punk hellhole where the only law is fuel, and the only exit is glory. Every run, you forge yourself into something the Empire has never seen before. Something worse.
Will you go full gas-powered berserker - raining down homing explosives like a one-man apocalypse? Or become the cold, calculating V8-powered crossbow sniper who wall-runs through the carnage and slides between corpses like death itself on a lunch break?
Multiple warriors of ruin, each packing their own weapons, abilities, and progression trees built for one purpose: maximum devastation.
70+ game-breaking perks that stack, synergize, and combine into builds so powerful, they should probably be illegal.
THE CROWD IS YOUR JUDGE. YOUR JURY. YOUR FUEL.
In the DIESELDOME, 50,000 screaming animals in the crowd hold your fate in their grease-stained hands. Give them a SHOW. Master the combo system, paint the arena red, and watch your popularity rise with every roaring ovation.
Unlock new skill trees, maps, and passive abilities through randomized bets — because fortune favors the savage.
No two runs, nor any two massacres are ever the same thanks to the randomized in-game event system
Face 10+ boss abominations built like nightmares and tuned like muscle cars.
And if you become the ultimate gladiator? They say Caesar himself is waiting for you. He's been waiting a long time.
A BRUTAL ROGUELITE TOURNAMENT MODE
Tournament Mode throws you into a procedurally generated meat grinder disguised as a gladiator tournament. Every fight comes stitched together from fresh insanity: new objectives, new modifiers, risky bets, new side events, new ways to die screaming.
One fight might turn you into a wall-running execution machine carving through hordes at terminal velocity.
The next might lock you in a steel coffin with flaming psychopaths and call it “sport.”
Complete side objectives for Caesar Chests packed with relics, gamble your earnings for Oil and rewards powerful enough to get outlawed by three separate empires. Trade perks. Break builds. Become a gas powered problem nobody knows how to solve anymore.
After completing a bracket you can cash out and crawl back to the Ludus with your pockets full of Oil and most of your organs still attached.
Or keep going.
Push deeper into the tournament where the crowds scream louder, the challengers get meaner, and every arena starts feeling less like a competition and more like a public execution with sponsorships.
The Empire doesn't remember the cautious.
It remembers the maniacs who kept going.
PARKOUR OR PERISH. THERE IS NO IN-BETWEEN.
Your body is not flesh. Your body is a V8 engine WRAPPED in flesh. Wall-run. Slide. Grapple. Glide. Move like the arena's trying to kill you - because it is.
The Dome's machinery never sleeps. Platforms shift. Arenas reconfigure. The challenge evolves. Only the worthy find a way through.
Master the movement, and you won't just survive the Dome. You'll own it.
Features
Different playable characters, each with unique weapons, abilities, and progression trees.
Over 70 unique game-changing perks that can be synergized to devastate the Dome.
Unlock new skill trees, characters, maps, and passive skills while taking randomly generated bets.
Encounter randomized events and goals, making every match a fresh, unique challenge.
Face over 10 abominations and bloodthirsty bosses with unique move sets. They say Caesar himself awaits those who become the ultimate gladiator.
Parkour your way to glory by wall-running, sliding, grapple-hooking, gliding, and more.
Encounter unique mini-quests while in a run, such as marksmanship challenges and races, and win unique rewards by opening Caesar Chests.
A tutorial level that introduces the world and gameplay of DIESELDOME.
Unique collectible power-ups that turn you into a god for a short time.

10,000 Wishlists - Thank you.
Greetings Domerunners! Today is a bit special for us, because we've just reached the 10,000 wishlist mark on Steam! Normally, we'd insult you all for crowding up the Dome with 10,000 plebeians, but we're too grateful to insult you like that...you mongrels. Truly, thank you.Who are we?We'd like to take this opportunity to talk a little bit about ourselves and how we've been working for nearly 3 years at this point on this weird, weird game. We're GHST Studios, a 3-person team, mostly self-funded micro-studio based in Istanbul, Turkey. 2 of us have been best friends since kindergarten, and even back then, we've been dreaming of making games of our own. We'd play with Legos, talking about how we would make our game one day and trying to build it from bricks. That's where our logo comes from! Along the way, we've added another weirdo to the team and decided to make our childhood dream a reality. DIESELDOME itself was supposed to be a much smaller game with simple FPS and Vampire Survivors-like mechanics, but we've now come to realise that we simply love this universe and game way too much to leave it as a small idea. Dieseldome - 2.5 years agoDuring our 3 years of development so far, we've been faced and then faced again with the dire challenges indie studios encounter when trying to create something they are proud of. It's a tough business, truly is.Dieseldome - 2 years agoThis is why 10,000 wishlists means more to us than you can ever imagine. It means that in one way or another, what we've been losing our minds over for the last 3 years of our lives wasn't for nothing; that 10,000 people looked at this thing and said, "Yeah, that kinda looks cool."Well, we think you look cool, you cool-lookin' handsome devil, you. We will do our very best not to let you down and to get you to live the power fantasy that DIESELDOME aims for when it fully releases. Until then, thank you!That's it for now! Make sure to join us on our Discord and celebrate with us!Discord: https://discor...Read full article on Community Announcements (GHSTStudios)Community & EventsOfficial

DIESELDOME - Introducing Tournament Mode
Salute DomeRunners!Today we're excited to finally introduce our largest update to the demo yet: Tournament Mode! Before we dive deep into Tournament Mode's very work-in-progress guts, let's take a look at this overview video:Tournament ModeOverviewTournament Mode introduces a procedurally generated roguelike tournament with different maps, mutators, modifiers, random champions, and mini quests. Domerunners can unlock new sub-classes, use relics, gamble, bet, and rise up in the tournament to become the champion of the Dome.Ludus/Sub-class SelectionOne of the first things you'll choose before starting a new tournament is your gladiators' Ludus, or as plebeians might call it, Sub-Class. Each gladiator now has three Ludus options that drastically changes the way you can create builds with them. For example, the Heavy Gunner Ludus of Spartacus lets you create a gambling build that gets more and more powerful as you do so. See, mom?! I told you my gambling addiction wasn't useless!The QuartersBetween fights, you'll get to prepare using various means in the quarters. Let's take a look at what you can do:Go to the Quartermaster and use your hard-earned gold to purchase new perks, relics, and consumables, or gamble using The Dice™ to earn enough gold to finally move out of your cranky old mother's house. That'll show her.Go to the Character screen to sell your perks and relics, allowing you to change your build in the middle of a run, or letting you buy that perfect relic that will complete your build when you're low on gold.Check your Tournament Progress to see how many fights are left until you face a Bracket Champion, or learn what your current bracket is. The tournament will double down on the challenges it throws at you as you jump up in brackets.See what the crowd thinks about you with the Popularity Meter. You will earn increasing rewards and Oil, the new Meta-Game currency, as you level up your popularity. You can increase your popularity during fights using our reva...Read full article on Community Announcements (GHSTStudios)Patch NotesOfficial
DIESELDOME: Oil & Blood Major Update - Wretch - Debut Festival 2025
Greetings DomeRunners! Today, we're launching the Wretch update, which yet again introduces a slew of new content, features, and improvements. This update has been tested a bit less than we'd like, so keep an eye out for frequent hotfix updates this week! We're also going to be part of the Debut Festival 2025 which starts today! Now, let's check out what awaits you in the Dome:Perk Overhaul & New Perks For this update, we have remade nearly every perk (We have more than 70+ perks in the demo now!) in the game. Most perks are completely new or work differently now. Our main reason for this rework was to give each perk tree a more distinct identity for making more focused builds. Let's see just a few examples of the new perks: Monument of GloryThis V8-Powered monument drops from the skies to those that deserve it. While within its radius, your weapons are significantly powered up!Effectus Coriolensis & Gauge Increase These new perks actually adjust the size of your projectiles. Effectus Coriolensis increases the size of your bullet over time, and Gauge Increase increases it overall even further. Sometimes you can even end up creating building sized bullets! Shoulder Missile RackThis perk adds a shoulder mounted rocket launcher that homes in on enemies. It is a great defensive perk that covers your back.There's many, many more new perks to try out in this update, but we'll let you discover them yourselves! Tutorial LevelWe've added a whole new dedicated Tutorial in this update. Our old tutorial was a makeshift solution that didn't teach our movement mechanics properly. The new tutorial scene gives players a proper introduction to both our world and also game mechanics. All core aspects of the game are taught step by step in the dark pits below the arena. We also get to see Spartacus rise from a lowly wretch to a DomeRunner. Check it out: Enemy AI & Spawning System Rework Abominations of the Dome are much more dangerous now thanks to reworks to our AI and spawner system...Read full article on Community Announcements (GHSTStudios)
