Sigerous (SGM) comes from a Russian development team that's headed up by Nikolay Bolotov (GeJorge), It was in development for many years and in that time a number of excellent versions were released. The plan is to upload a selection of All-in-ones that span from SGM 1.7 up to SGM 2.2. Note: I'm not one of the mod's developers, my involvement has been through doing the English translations from 1.7 Geonezis on. Each mod will come with a read me that gives you any relevant info you'll need and a list of known contributors.
This is the full 2.1 translation it also includes the Dynamic news script files that were translated by Spaceghost (GSC). This is already included with the 2.1 all-in-one. Artwork by Alexander Rudenko
