maybe change these to something else, because earlier it had been described as a "war walker", which to me implies a mech of some kind.
also, where is it getting the extra weapons from in this situation? in the scene im painting in my head, it had only just plopped out from the vat, then merged with the war walker to gear up for the fight.
In the blink of an eye, the PA-X merges with the towering battlesuit. The orange goo engulfs the chromed exoskeleton, seeping through its joints and creases. Servomotors and weapon systems spark to life, powered by the amorphous creature’s bioelectric potential. It moves the cumbersome armor moves with a supernatural deftness, using its wobbling elasticity to integrate extra missile launchers, railguns, plasma beamers, geddanium plates, and serrated blades into the powersuit’s deadly arsenal before setting its bright yellow eyes on you.
