Evaluation

MADNESS: Project Nexus launched on September 29, 2021 and has received sustained post-launch development from its two-person team ever since. The game received a major story content update on April 11, 2023 ("Legacy of the S-3LF Eater"), and since then the team has been building out a comprehensive modding and Workshop support system — a multi-year initiative with regular public milestones. Workshop modding tools launched in beta on May 24, 2024. Custom Scene Tools were released on November 2, 2024. By August 6, 2025, the team had shipped support for full custom cutscenes and multi-stage custom campaigns, describing ongoing cleanup and new features still in the pipeline. On February 16, 2026, a patch update confirmed that Vessels and Character Refs were nearly ready for public beta testing. The most recent update — a beta branch patch on April 15, 2026 — delivered the live beta for those Vessels and Character Refs systems, along with new modding tools including Custom Seats and support for Harmony 2.4.2 assembly loading. The developers have been explicit that they are not done. On the game's third launch anniversary (September 29, 2024), the developer wrote: "It's been three years since this 8-year project finally launched, and we're still adding content." The August 2025 post stated: "We're far from done with tinkering and giving you guys new features." No final update announcement or statement of completion has been made. The last developer communication was on April 15, 2026. As of today (August 24, 2026), that is approximately four months of silence — consistent with this team's historical pattern of updates every few months, and well within the established cadence.
Evidence

About this game


MADNESS: Project Nexus is a third-person Run n' Gun / Beat'Em Up filled with arcade-style action and button-mashing brutality. Shoot, stab, bash, chop, and slaughter your way through over 16 hours of intense combat. Your wits will be challenged. Your nerves will be tested. Blood will probably get all over everything... what a day to leave your raincoat at home! But that's alright. Wading through the dismembered remnants of those who fell to your bullets and steel, only one thing crosses your mind: They asked for this. And you're glad that they did.

  • STORY CAMPAIGN
    [Solo & Local Co-Op] [8+ Hours]
    Take the reigns of the antiheroes of the Madness universe! Infiltrate heavily guarded installations, survive cultist-ridden tunnel networks, fight back against dynamite-wielding cannibal bandits, and dodge the grasp of armor-plated Mag Agents over three times your size...all while unearthing the terrible secrets of Project Nexus itself.
    Play solo or locally with up to three other people (using Xbox-compatible controllers).
  • ARENA COMBAT
    [Solo Play] [8+ Hours] [New Game +]
    Build your custom warrior from the ground up! You'll advance through specialized skill tiers and train a unique Madness warrior who is equipped to take on wave after wave of never-ending badguys in combat environments that range from killer game shows to haunted houses to high speed trains. Build your own custom weapons and outfit them with the latest technology to give yourself the edge you're going to need to pull through.
  • THE PLAYGROUND
    Play god in a secure combat environment and pit squads of badguys against one another for your own satisfaction. Toss them any weapons you like, or have them go at it with their bare fists. Or, jump down into the fray yourself and show them who's boss!


    ABOUT US
    Hello! We're Matt Jolly and Michael Swain, two smalltime game developers who spent seven years bringing this project to life. It was inspired by our love for the side-scrolling button mashers we grew up with, and if you feel the same, then we can't wait for you to jump straight into the carnage!
