Sigerous (SGM) comes from a Russian development team that's headed up by Nikolay Bolotov (GeJorge), It's been in development for many years and in that time a number of excellent versions of the mod have been released. The plan is to upload a selection of All-in-ones that span from SGM 1.5 Braz up to the current SGM 2.2 and possibly any future release. 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
