i have some concepts that could be useful!
As we know, taking super-villains alive is hard, especially when they cause riots, power struggles, or taking people alive for informaiton...
thats why i think developing the Arc thrower/pistol/Rifle could be DAMN useful for humanity, (the idea is from X-com, both the mod of long war AND enemy Unknown/Within)
The idea comes from that ark throwers linage could be helpful in subduing riots and people when particular incidents happen with a perfectly fine non-lethal setting. Thus allowing police to have a tool for near perfect take-downs when criminals get violent.
however as the Mark 1, the thrower would have limited charge and thus need a battery change, (around 4-5 people take-down charge at 33% health for meta-humans depending on their stats).
The Ark Pistol being the Mk 2 of the series would be even easier to use then the ark thrower, allowing for more range rather then the taser range that police have to employ, not to mention being able to utilize as well. (around 66& of meta-human fighting capability, and possibly 33% of super-being capability...normal humans and average joes? no chance to suceed in resisting it!)
the Rifle would be a Mk 3 version, able to take down meta-humans and have a reasonable chance of knocking out super beings...not to mention improvements overall.
[] Ark Thrower technology
(with possible upgrades to pistol, rifle, and grenade/explosive later on, the grenade type is to take down very hostile people, and thus allow special forces and our own guys to clean out rooms without wasting life and ammunition.)
