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 along with the Dynamic news script files translated by Spaceghost. Artwork by Alexander Rudenko
