Planet N-1

The parasites didn't seem heavily interested in trying to assault the cities as of yet (the gas clouds might get a few once they arrive, but the hive was more interested in biomass) and instead set about converting the tree's and wild life

The infected ship that had deployed the forces continued to glide forwards... And released another form. These pterodactyl like creatures were at least twice the size of an average "hunter" soldier, and they possessed a corrosive spit. Four of them were released, and they set off towards the transport that was evacuating people, eager to reach it and try to bring it down

The infected ship turned its attention towards the cargo ship and explorer and glided towards them, trying to take position between them, presumably in an attempt to broadside them both.
The other two ships glided forwards to engage the other cargo ship, eager to destroy it before it could prove any sort of nuisance to the infections spread. The derelict ships remained perfectly still, performing no functions at all but to sit there, drifting in the weightlessness of space...
