It'd need to be hardcoded to go off if someone touches you or gets too close. Otherwise it's rp fluff no one here buys into.
I tried a standoff the other night. I was just bum rushed with tasers that took both me and the hostage down. Make it so that if they taze your hostage first you kill him?
It could have the whole thing where you can toggle how it behaves, like if it fires when they resist or if somebody gets within a certain amount of tiles.
There's also the fact that a dead hostage can just be cloned. Traitor gun that scrambles hostage DNA or brain matter to prevent cloning? This would FORCE responders to be careful.
Not really if it requires an aggressive grab. You're super obvious, hostage has a chance to escape before being grabbed, the attacker is immobile, and it's not even the fastest way to kill if you're REALLY a bad guy with a REAL gun.
A good idea. The hostage should be able to resist out of it, and like getting out of handcuffs it wouldn't be instant. I'd say ~3 seconds would be reasonable, giving the gunman a chance to grab them again or just shoot them.
