Achilles Modding Studio creates aircraft, vehicles, and gameplay frameworks for Arma Reforger, guided by a focus on realism, immersion, and innovation. Established in 2024, the studio builds its addons around shared technical foundations: a common flight core for aircraft, an ordnance package, and a vehicle core pack. This approach is intended to make its creations work together as a cohesive fleet across air and ground gameplay, rather than as unrelated downloads.

Its roster spans rotary- and fixed-wing aircraft, ground vehicles, naval systems, and other gameplay features. Available aircraft include the HH-60W Jolly Green II, MH-6J Little Bird, F-14D Tomcat, and F-35B Lightning II. Ground offerings include the M-ATV and M1083 FMTV A2, while naval content includes the Dark V and Combat Raiding Craft. The studio also offers systems such as the K9 Working Dog and Cargo Delivery System, alongside shared framework addons. Its catalog identifies content as available, in development, or unreleased, and the studio provides a flight manual, installation guidance, and channels for requests and bug reports.
