This is the new Mutant Cyborgs Mission image - C&C Tiberian Sun: Tech Level War mod for C&C: Tiberian Sun Firestorm

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.
