Madness: Project Nexus is a Madness Combat game. It was also unofficially referred to as "Madness Interactive 2" by Krinkels. It was released on March 25th, 2012. The current version is V1.8, last updated September 9th, 2014. The development team is as follows:
- Krinkels did art and design.
- The-Swain programmed all features and groundwork for the combat system from scratch.
- Cheshyre provided most of the soundtrack; Devin Martin provided the track Killbot and Horror Stereo provided the Skynet VIP remix.
- Luis designed the UI and menu system
- Afro-Ninja and Mike provided code support at various times.
The game focuses on episode-based gameplay, with different characters to play as, along with an Arena Mode where you can create and upgrade your own character who you can customize with gear and weapons. There were originally 3 Episodes planned, with an appearance from the entire Madness Combat cast.
According to The-Swain, Madness: Project Nexus was supposed to be a simulator of the Madness Combat episodes, placing them right in the middle of the action that made the series popular. 
According to Krinkels, Madness: Project Nexus cannot be updated anymore. Certain symbols keep on swapping around with other ones, and et cetera. 
A sequel, Madness: Project Nexus 2, is currently being developed by Krinkels and The-Swain using Unity engine instead of flash.

A special attack is a charged attack that, when performed, will knock down the player, penetrating the player's TAC-Bar and causing damage. It can be prevented by wounding/killing the opponent or by dodging/blocking** the attack at the last second.
**Blocking fails for lower-skilled characters, such as Sanford and Deimos.
Story Mode is a game mode that allows the player to play as one of Madness Combat's main characters. Each level has its own goal and must be completed in order to unlock the next one.
Arena Combat is a game mode that allows the player to use a customized character to fight enemy units in an arena. These units consist of the enemies seen in Episode 1 of the Story Mode such as agents and G03LMs. Every kill gives the player a certain amount of experience and money. After gaining a certain amount of experience, the player will level up and be awarded with points that can be spent on increasing stats or gaining weapon perks. Money can be used to buy weapons and hire mercenaries for the player's team.
