Engineer weapons in future films

Whether Alien: Covenant sequel will happen is still under the question mark. If it does happen, as fans speculate, there will be a battle against humans, xenomorphs,
and engineers. RS said long ago that there will be 3 or 4 players coming in to investigate, and one of them will be engineers coming to find their planet decimated.
Since there might be a battle (in the 3rd act most likely), I highly doubt engineers would go into a fight barehanded.

In Jon Spaiht's script Alien: Engineers, after Engineer is awakened by David, he steps into a sarcophagus against the wall that equips him with a bulletproof
flight suit. When the crew follows him to the pilot room the Engineer shows up equipped with some kind of obscure devices clutched to his fists that he uses to
kill some of the Magellan crewmembers. Those devices are capable of firing nearly invisible missiles or forces that were described as "knots tied in the fabric of space itself", and are capable of crushing living things like insects with intense force.

Thought dark horse comics fire and stone/life and death wouldn't really be considered canon, we did get to see engineer weapons.
One was a rifle that was used by character Galgo throughout the comics. That weapon was incredibly powerful. According to some of the people who worked on the comics,
that weapon was originally supposed to suck the environment and shoot the black liquid, but for some reason, they changed it.
Another weapon was used by the engineer to eradicate the xenomorphs and humans. That weapon acted like a flamethrower but instead, it fired pink aura that was capable of erasing anything from existence insight.

Knowing RS and the tradition of using unused concepts from older films/scripts for new films, I wonder what will they use, or what will they come up with. Any ideas?

Also, BigDave, no offense but let's try not to go off-topic and not turn this thread into why Engineers are smaller/different than the Space Jockey, etc, ok?
