okay i've been digging around online:
im thinking this is a good basic infantry:

rebel scrin flame tank type thing. that back pod MUST explode when destroyed and spray goo/tiberium everywhere, in TW it doesn't and that pisses me off

meh, maybe some kinda drone like a limpet or a terror drone, certainly not what TW had it as.

oh and you all know what the primal looks like correct? we DEFINITELY should use that
