Well, I've been losing a lot of sleep thinking about a launchable version of my grenade.
I came up with an impact trigger last night that is armed by the launch impulse from an underslung rifle launcher. I'm hoping there's enough consistency between launcher manufacturers that I can make a generic grenade for most launchers.
I have to tackle the problem of reducing my grenade weight even further to prevent a player from blowing the goggles off of someone else though. That is probably going to be the biggest design challenge which might make me abandon the launched grenade.
