Hey CDRMV,
This a large number of units. I love some cool ideas : drone station defense, Mass&Energy 2in1 storage, tech 2 walls. That a big numbers of hours of work.
Maybe some balance issues : tech 1 mass reactor cost 56 mass and gives a +5 mass -90 energy. That is a 18/mass energy ratio, which is too generous. Given to cybran only, this kind of imbalance will broke all games played with your mod.
Some units seems well balanced, with i think you need to put some effort on it.
Good work anyway !
