Joking aside, I'd be on board for knocking out high energy physics in the next turn.
Less dramatically (and also with less venting) from me also, I've been really considering Gravity Weapons. Immediately give us new weapons "infantry, vehicles and warships" while also half of the tech for Nova Cannons. And gravity weapons have wonderful variety of uses. Non-lethal at low power and can be used for capturing targets. Yet they are
also good at killing hardened and big targets like power armor equipped foes, and excellent weapons for collapsing fortifications. In fact, they become more powerful the more the target has mass due to the nature of the weapon.
On more specific canon-confirmed positives, "extremely useful when fighting on a starship or zero-gravity environment" and "its primary use is to impede the enemy and damage machinery
" according to the
lexicanum. Those sound like excellent qualities in a weapon to use to give a very nasty time for any boarders that might try to invade the
Spark.
And good weapons to compensate for the shitty close-/melee-range capabilities of our bots. Hard to charge our bots to smash them apart, when you and your equipment suddenly weight ten times more than a second ago. Or maybe you are just floating in the air suddenly, exposed for our bots to shred with their considerable firepower.
Funnily enough the greatest known ship-scale gravity weapons in the canon is from the Orks. Though tbh, way
past the normal ship scales. Because the Attack Moon o had "Gravitic Whip" that could "decimate entire squadrons of Cruisers and crush even Battleships in a single volley" according to our good friend the
lexicanum once again. Of course, we would be working on that scale. But I think we could still potentially get some neat stuff from this part of the physics tech-tree.
