Diluvian Ultra is a retro first-person shooter that places players in the role of the immortal warrior-prince Atilla aboard a living tomb-ship drifting in deep space. The title blends fast movement with deliberate weapon choices in a single-player campaign built around organic and technological armaments. Atilla awakens to intruders who have defiled his vessel, prompting a direct response through close-quarters strikes and ranged fire.
Gameplay
Combat revolves around a dual-damage system that requires players to strip armor from foes before landing a killing blow. Certain weapons excel at removing protective layers quickly while others deliver the final strike once defenses are down. Enemies employ similar tactics, forcing constant adaptation during encounters. Blood collected from defeated opponents fuels weapon upgrades, and temporary power-ups can shift the balance in intense moments.
Mobility forms the core survival strategy. Double jumps, dashes, ground slams, and projectile deflection with the sword keep players in motion across the ship's cathedral-like interiors. Standing still invites concentrated enemy fire, so chaining ranged shots into melee finishes and evasive maneuvers becomes essential. The environment itself mixes flesh and stone, reflected in the arsenal that includes both conventional tech guns and grotesque living organic weapons.
A sentient companion known as the Squire Gun Bella accompanies the player at all times, adding another layer to loadout decisions. Six base weapons receive up to thirty distinct upgrades across the campaign, while thirteen enemy types present varied threats that reward observation and positioning.
Game Modes
Diluvian Ultra operates entirely as a single-player experience. Chapter One delivers ten distinct levels linked by a central hub area where players manage upgrades and prepare for the next section of the ship. Progression follows a linear path through these spaces, with combat encounters and exploration driving advancement.
No separate competitive or cooperative modes exist. The structure emphasizes repeated runs through the levels to experiment with different weapon combinations and upgrade paths. Further story chapters and additional content arrive through planned paid expansions that expand the enemy roster and arsenal.
Story and Atmosphere
The narrative follows Atilla's awakening after millennia of slumber and his efforts to reclaim the tomb-ship from invaders. Themes of fanaticism, trauma, betrayal, and the possibility of redemption unfold against neo-gothic architectural backdrops filled with immense, cathedral-like chambers. The living ship serves as both setting and antagonist, its corrupted state mirroring the prince's own fractured past.
Atmosphere draws from the contrast between ornate stonework and pulsing organic matter. Sound design and visual details reinforce the sense of a once-sacred vessel now overrun, guiding players through increasingly hostile corridors without relying on cutscenes for every beat.
Is It Worth Playing?
Steam user reviews stand at mostly positive based on 149 ratings. The game appeals to players who enjoy retro-inspired shooters that reward precise movement and layered combat decisions rather than pure run-and-gun action. Those seeking a compact campaign with room for experimentation through upgrades will find the ten levels plus hub structure satisfying for multiple playthroughs.
Patches continue to address technical issues, and the developer has confirmed the current release functions as a complete standalone experience while leaving the door open for future story expansions. Fans of indie first-person shooters that combine mobility with strategic weapon use will likely appreciate the focused design, while players expecting extensive variety or multiplayer options may find the scope limited to the single-player campaign.
