The Armatus demo lets players test Counterplay Games and publisher Fictions' third-person roguelite shooter set across the demon-ravaged ruins of Paris. Armed with a scythe, firearms, and celestial powers, players fight through randomized combat encounters leading up to an encounter with the area boss, The Monument.
Below is an overview of verified system requirements, available weapons, encounter mechanics, and community-tested fixes for technical issues reported during the demo period.
Armatus Demo System Requirements and Install Size
Steam store data confirms that the Armatus demo requires 60 GB of available storage space. Player reports show a compressed download size of approximately 30 GB to 38 GB, unpacking to roughly 58 GB on disk. Counterplay Games noted in forum threads that these hardware targets are temporary specifications for the demo build and will be updated ahead of the full release.

Weapons and Celestial Combat in the Demo
The demo equips the player with a melee scythe alongside a choice of firearms and celestial skills. Combat rewards and upgrades selected at altars appear in subsequent void rooms rather than activating instantly.
- Submachine Gun (SMG): Delivers rapid automatic fire suitable for close-to-medium encounters.
- Assault Rifle: Offers standard mid-range automatic fire, though multiple players noted it requires sustained hits against spongey demons.
- Marksman / Precision Rifle: A high-damage semi-automatic option that synergizes heavily with headshot perks and enemy-marking mechanics.
- Shotgun: Delivers close-quarters burst fire against charging demons.
- Celestial Abilities: Usable special powers include holy fire, dive bomb ground slams, and time-slowing fields that grant temporary combat advantages such as sustained damage windows.
Encounter zones between boss arenas feature distinct wave objectives, including cocoon clearing rooms, timed survival challenges, and Defend the Pyre defense stages.
How to Defeat The Monument Demo Boss
The Monument serves as the primary boss encounter at the end of the demo run. The fight takes place in an enclosed arena where the boss combines frontal shield protection, heavy charges, and spawned environmental obstacles.
- Bait the Charge Into Arena Walls: The boss's shield blocks direct frontal damage during normal states. When The Monument charges, dodge out of its trajectory so it slams into the perimeter wall. This stuns the boss and leaves its vulnerable back exposed to weapon fire and high-damage celestial skills.
- Clear or Crash the Pillar Hazards: The arena spawns pillars that generate slowing, sticky fields across the floor. You can destroy these towers either by directing the boss's charge paths straight through them or by using burst skills.
- Prioritize the Boss Over Endless Adds: Floating orb enemies spawn continuously during the encounter to spam slow effects. Player testing indicates that spending all your ammunition clearing these flying adds lengthens the battle and lowers damage output. Focus movement on repositioning away from ground pools and concentrate burst damage on the boss during stun windows.
- Leverage Slow Time Powers: Activating time-dilation skills right after the boss collides with a wall maximizes the duration you can fire into its critical hit zone without interference.
Known Demo Bugs and Technical Fixes
Player reports across the Steam forums during Steam Next Fest highlighted several performance issues with the Unreal Engine demo build. Community members identified specific workarounds for common technical hurdles:
- Aggressive Motion Blur: Even when toggled off, motion blur may remain active. Setting Post-Processing to Low in the graphics options resolves the persistent camera smearing.
- The 1 FPS Cap Glitch: Setting manual frame rate limits in the settings menu can occasionally glitch the game into an unplayable 0 or 1 FPS state. Reinstalling the demo or reverting the display settings restores default frame rates.
- Black Screen on Boot: Adjusting certain graphics presets can cause menus to become unresponsive or launch into a black screen with background cutscene audio. Players can skip past the intro prompt at the bottom right of the screen.
- Controller Audio Slider Navigation: The audio sliders do not move by standard directional input on gamepads. Players must press the A button and drag the Left Stick sideways to alter volume values.
Armatus Full Game Release and Future Playtests
According to official Steam community announcements, Armatus is scheduled to release on January 7, 2027. Counterplay Games and publisher Fictions host player registrations for future pre-release playtests through their Firstlook portal at armatus.firstlook.gg, alongside developer discussions on the official Armatus and Fictions Discord servers.

What platforms is the Armatus demo available on?
The demo is supported on Windows PC via Steam, featuring full controller support for standard gamepads as well as DualShock and DualSense controllers through Steam Input.
Why is the Armatus demo download so large?
The demo requires 60 GB of storage space because the build packages high-resolution assets and core system frameworks. Counterplay Games confirmed on the Steam forums that the development team is actively working on reducing overall installation sizes for subsequent builds.
