OMSI 2 Alternatives in 2026: OMX, openOMSI and the Forks
A look at OMX, openOMSI, neoOMSI and Sobol3D Edition: what each project does, which ones you can try, and why we're building OMX differently.
A new engine for OMSI 2 content
OMX is a from-scratch, 64-bit implementation of OMSI 2. It reads the buses, maps, scenery, scripts and add-ons from your existing installation and aims to reproduce the original simulation’s behaviour.
It is not a remaster, mod pack or replacement for owning OMSI 2. It is unfinished software in beta.
