OUR HISTORY

From development
to the company.

Several years of experience from private FiveM projects form the technical foundation of SQL Modifications.

2022–2025
DEVELOPMENT EXPERIENCE

Milsim RP & classic roleplay

From 2022 to 2025, the future team worked as developers in milsim RP and classic roleplay, gaining experience through private FiveM projects. Initial sales structures were established at the end of 2022; from 2023 onward, documented sales and extensive work on Bundeswehr EUP, maps, props, and combat, vehicle, logistics and capture systems followed. This is where our roots in the former FiveM milsim scene lie.

2026
COMPANY FOUNDATION

SQL Modifications is founded

SQL Modifications was founded as a company in 2026. Before that, the team had already gained experience through private development projects in the FiveM environment. After the milsim scene became progressively smaller following new FiveM requirements and the previous direction no longer offered us a sustainable future, SQLCODE shifted its focus to scripts, MLOs and EUP for classic German-speaking roleplay. Since 1 September 2026, all former milsim scripts have been offered together in the Milsim Legacy Pack.

LEGACY

Legacy & Milsim

Our roots include FiveM milsim. Today, our main focus is on classic RP systems, while selected military systems and earlier projects remain part of our portfolio and technical experience. Available since 1 September 2026, the Milsim Legacy Pack brings together our former milsim scripts.
