Let me introduce you to Tiberian Sun: Tech Level War. It's a mod with a new gameplay tweak, in which you have to build very expensive buildings - the tech centers - in order to level up and have superior buildings and structures and eventually win the battle. However, there are not useless units in the lower tiers.
Nothing new, this is a pack that includes the mod version 0.3 along with the patch 0.31, there's no need to download it if you already have those two...
Installation Instructions: Just unzip into the Tech Level War folder. Hope you like it!
This is the Beta 0.3 version of my mod. Hope you like it! Any comments, suggestions, bashing, etc. are very welcomed and please put them at the main page...
