This mod is provided as a standalone version. You don't need Tiberian Sun to play this. GDI, Nod, the Forgotten or CABAL. Who will triumph the endless war? This mod playes after the storyline of Firestorm. Command new units, conquer harder enemies. Will you save Earth or will you destroy it? It's your choice...
Some constructive criticism. There's a ton of balancing problems between units and factions; some of them are so OP they can take out buildings and units in a matter of seconds without any other tradeoffs.
Having a nice assortment of units is nice, but too much is unnecessary especially when some of them are repetitive. Try to avoid the coolness and eye-candy mentality (i.e. I just gotta have it in there cuz it's cool!) and focus on what's really important from a game design perspective. In fact there's so many, if you capture another faction's MCV and tech up, the game crashes. TS has a limited amount of cameos it can take.
Other than that, it really gives the game a good refresh. I can tweak the rules.ini for better balance and cut down on the plethora of units to eliminate repetitive roles.
