R.E.A.R.M. - "Rearmament Expansion And Redesign Mod" is an unofficial Homeworld 2 expansion and it adds number of new interesting and various units.
Keep in mind that it is in fact a work in progress preview and that the mod has been on hold for a quite a long time. This version contains placeholder and WIP ships (as the one on the picture), so if you don't like your mod in a rough state, you better wait for another version (which shouldn't actually take year and a half this time).
The way I always describe the current version is that nothing that specific happened, yet those "unspecific" changes made the mod more confortable to play and subsequently made the previous version practically unplayable for me. See for yourself. I've completely lost perspective on how much different this version really is, so feel free to report wheter it's practically the same thing or wheter things actually changed.
