ONI-CORPS for Cortex Command Community Project introduces a unique faction called OniCorps, featuring an array of characters and weapons. This mod enhances gameplay by adding three distinct bodies: Light, Heavy, and Siege Drone, each tailored for specific combat scenarios. The Light and Heavy infantry offer standard and robust options for ground assault, while the Siege Drone specializes in demolishing fortified structures from afar. Players can also deploy the Assault Mecha, a formidable unit designed for heavy combat and equipped with a powerful Reaper autocannon.

In addition to the diverse characters, the mod includes a Cargo Ship for tactical transport and a variety of weapons, such as the Bombard rocket launcher and the Wolf Magnum sidearm. Each weapon is crafted to suit different combat situations, ensuring players have the tools needed for any encounter. With the ability to summon an Assault Mecha via the OniCorps Beacon, this mod significantly enriches the gameplay experience in Cortex Command.
