PETAFAB: Bot Invasion Launches on Steam: 540Hz Targets, Late-Latch Input, and 100% Destructible Environments
Competitive shooter enthusiasts frequently face a frustrating tradeoff: modern releases pack visual spectacle at the expense of frame stability and input response, or strip graphics down to the bare bone to preserve low latency. Industry veteran Sebastian Aaltonen aims to eliminate that compromise with the upcoming launch of PETAFAB: Bot Invasion on Steam on November 6, 2026.
Built completely from the ground up without commercial engine bloat, the single-player first-person shooter delivers complete level destruction, vast crowds of hostile robots, and input latency parameters engineered specifically for high-refresh display hardware.
The Story: Infiltrating the Machine Megastructure
PETAFAB centers on the world’s largest automated robot manufacturing facility. Expanded by autonomous builder bots across decades, the facility has grown into an industrial complex the size of a metropolitan city. When the central operating AI severed outside communications, automated production went rogue.
Players control one of three special forces operatives deployed into the complex with a straightforward directive: penetrate the automated defenses, take down towering factory bosses, and destroy as much of the facility as possible.
Custom Tech: Signed Distance Fields and 100% Level Destruction
Rather than utilizing off-the-shelf solutions like Unreal Engine 5 or Unity, PETAFAB runs on a custom engine built on NoGraphicsAPI, Aaltonen's low-level GPU interface. Aaltonen brings 30 years of development expertise across Frozenbyte, RedLynx, Ubisoft, and Unity, having previously spoken at SIGGRAPH and GDC on advanced rendering pipelines.
The visual foundation trades out standard polygon rasterization shaders for Signed Distance Field (SDF) ray tracing and mesh shaders. Evolving the fluid and matter simulation systems pioneered in Claybook (2018), every floor, catwalk, support pillar, and wall inside PETAFAB is 100% destructible.
Instead of pre-baked destruction animations, explosive blasts dynamically carve physical craters through geometry. Knocking down elevated ramps causes structural collapses that crush approaching robot crowds beneath debris, turning the architecture itself into ammunition.
Native Performance Benchmarks: No Upscaling, No Frame Generation
Engineered specifically around multi-threaded hardware efficiency, PETAFAB delivers native frame rates without relying on artificial frame generation, DLSS, or temporal upscaling:
-
Top-Tier Desktop (GeForce RTX 4090): Stable 540Hz native performance at 1440p resolution on max settings, verified in developer and external tester testing.
-
High-End Desktop (GeForce RTX 4080): 240Hz native at 4K resolution on max settings.
-
Handhelds (Steam Deck OLED): Native 90 FPS running at panel resolution.
-
macOS & Apple Silicon: Native 60Hz on entry-level 8GB MacBook Neo hardware, a locked 120Hz on internal MacBook Pro Liquid Retina XDR displays, and up to 240Hz output when driving compatible external gaming monitors.
Audio production matches the high-octane tempo, featuring an original dynamic soundtrack and sound design led by award-winning composer Ari Pulkkinen (Resogun, Nex Machina, Super Stardust HD) under AriTunes.
Ultra-Low Latency: Integrated Late Latch with 8000Hz Mouse Polling
For competitive FPS players, high refresh rates only matter if frame times translate into immediate, tactile aim feedback. PETAFAB eliminates render-queue overhead with an integrated late-latch input pipeline, fully implemented in the launch build.
Traditional game engines sample mouse movements at the start of a frame tick, forcing orientation data to sit in a render queue for milliseconds before appearing on-screen. PETAFAB’s late latch samples and injects orientation matrices right before draw submission calls reach the GPU.
Paired with full support for 8000Hz polling rate mice, the input pipeline reduces reticle latency to sub-millisecond territory. In blind testing conducted with competitive esports players, testers praised the response as instantaneous, with multiple competitors reporting the lowest input latency they had ever experienced in any shooter. Reticle adjustments against massive swarms register without delay, even during intensive full-screen physics simulations.
Launch Details and Steam Availability
PETAFAB: Bot Invasion lands on Steam on November 6, 2026, for Windows and macOS (Apple Silicon). The game features full controller remapping, Steam achievements, and global score leaderboards for speedrunners looking to optimize destruction times.
