Find the recruiter of each planet and space station to recruit soldiers. From organics to cyborgs, from humans to aliens, this war has turned everything that can fight into weapons.
Troops include the Famas Infantries, with their brains being the only organic parts left after their transformation; the Bio-enhanced Ape Fanatics carrying high explosives for suicide attacks; the Beck Hospital Combat Nurses wielding alloy shields, among many others. Troops are of varying strategic significance. Choosing the right combinations and numbers of them, and giving them the correct orders on the battlefield can bring significant tactical advantages.
When your troops have accumulated enough battlefield experience, they will grow into more powerful units. Use them wisely, and keep them alive.
