Glasses that give you a heads up display. That could be useful.
I consulted Piecewise about a more inconspicuous, reliable alternative and it is indeed possible. We could make an implant that streams that data straight into your brain. No need for glasses that may break, get lost or draw too much attention.
Better armor. Shields maybe? Better, more useful, more versatile guns. More versatile support items? MOAR GENEMODS. More blops usable stuff, genemods and/or equipment?
Like the Spektr. Maybe like a set of weapons that all have the same ammo, but fill different roles? Laser based maybe? Blueradite based? For sharkmist based for manufacturing ammo.
For Blops, I'll have to go check with the Doctor on this, now that Xan's lost his abilities. But it should be possible to coat robobodies with a fleshy veneer. Not sure how well it work to evade detection from more sophisticated system, but should be fine for deceiving the naked eye. Well, up until shit hits the fan and people burst out of their fleshy coats like a bunch of clumsy, terminators a couple years off their prime. Since it makes regular robobodies look fat, I have a feeling that synthflesh bodies would look morbidly obese.
We do have invisibility cloaks, though blops doesn't seem to use them. There was the discussion of some sort of blitzkrieg option to allow them to move quickly and take out all witnesses, but no one really put forth any ideas for how to achieve this. One possibility is some kind of directional teleport system with an amp-like interface for course corrections, though that limits it to people with CON skill and high MIND. Another idea that comes to mind would be to replicate the vibrations of sharkmist to cause agitation in the general populace, though I'm not sure how useful it would be.
For pseudo-universal ammo, that's probably going to be far easier to implement for energy-based weaponry. It'll be a matter of debating adapters vs common ammunition. That is, whether to have units that can adapt one weapon's power source to another, or to just have them all run off the same thing. Adapters would probably take longer to use, but would require no real change to our existing weapons and would let us adapt our powersources to other implements, like those heat-guns that proved oh so invaluable during the Eater of Cold mission.
For kinetic weapons, I asked PW on IRC and apparently, it may be possible to grow weapons (mostly melee but also simple rifle) through some kind of yet-to-be-discussed mechanism. Perhaps it may be possible to grow ammunition using this process, though it depends whether or not the substance is ferromagnetic.
Versatility-wise, I'm not really sure what energy weapons need beyond wavelength, focus and intensity settings. For kinetic weapons, one possible idea to pursue to to just be some sort of kinetic-amplifier based system that just launches whatever gets shoved down the barrel, though that would probably have a rather low rate of fire. Another possibility is to have an electronically-fired superposed load weapon that can rounds one by one, discharge entire "ammo-tubes" as a lance of metal, or discharge everything as a large mass of white-hot metal. The plasma projector needs to be investigated as I suspect that it may use some sort of space-magic to keep its rounds from dispersing (electromagnetic fields should not be able to keep the shots in the shape they are in), if that can be analyzed further, it may be possible to create some smaller plasma or electrical weapons, possibly with firing modes that range from sprays to bolts to beams.
On the unconventional side of affairs, there's the weapon Charles is about to receive which is basically just a Piezoelectric Shard Launcher with all its firing mechanisms removed, so that it only costs 5 tokens and is used to create items like throwing knives, caltrops and trip wires. Basically, if you can shove something into it and have enough fluid, it can create piezoelectric crystals in its shape. Tripwires from it are quite weak but can still knock people out. Throwing knives are probably going to be significantly more powerful. Should probably look into whether my kinetic shunt cane idea would work, if so it might be usable as a shield, weapon and general purpose tool. There's also the possibility of having autonomous organisms partially contained in a weapon unit, so like a murder-tentacle in a scabbard that prevents it from hitting its weilder and whatnot.
Exotic is space magic. We don't really have access to that stuff. That's for ARESTEVE, The Doctor and R&D. With the symbiotic hives capable of chemical analysis, minor body modification, anti-infantry use and whatnot, I doubt they'll need anything more versatile right now.
Genemods are probably The Doctor's exclusive domain.
For equipment, I do have an idea to just have Charles with his (soon to be) +4 Charisma scream insults into a microphone and record them, then to have remote speakers that can play those insults to berserk enemies like how Charles was able to accidentally drive Xan into such a murderous rage that he was unable to use his amps and instead charged at him. Those units could also play other audio that the user gives them.
Alright, here's what I need: A badass fuckin' eyepatch. Hook me up.
How practical does it need to be? As in, could it just be a kinetic amplified strapped over your eyesocket which has been filled with blueradite? Nothing says badass like keeping an immensely powerful electrical capacitor in your skull right up against something that can discharge all of its contents upon activation. That discharge of contents was referring to both the capacitor and your skull by the way.
Again, this does depend a bit on the R&D people. I'm hoping that they've looked into weirdvision enough for us to make eye replacements with it inbuilt.
Something to let us avoid bullets and such, rather than wear a ton of armour to tank the shots. Something like Simus' phase suit or a weaker version of Renen's bullet time.
Phase armor depends on the R&D team. Bullet time depends on the Doctor. Invisibility cloaks we can do. Short-ranged personal teleportation as mentioned above
might be possible for those skilled enough.
