Search “Sticky bomb” in the workshop. It’s a fun weapon and slightly less op than what your thinking because it beeps
I have an original idea, so no Steam Link for this one:
Proposed Weapon Name - Prankster's Grenade
Weapon Icon - Frag Grenade
Who Can Buy - Traitors Only
Description of Mechanic:
I got this idea after watching a video on youtube about funny achievements in video games. The Prankster's Grenade works like the achievement Prankster's Revenge from the game Fallout 4, wherein it is a grenade that you can plant in someone else's (Detectives or Innocents only) pocket, and it has a short countdown (up to 10 sec?) until it explodes so the Traitor who planted it can run away.
There most likely is going to have to be a concept developed for the victim to try to avoid the explosion of this. My idea is to have the grenade act like the bomb from the fun round bomb rush, where it can be passed to others. However, it would have to be programmed to not be able to be passed to Traitors.
I don't even know if this fever dream of a weapon is even feasible to program into TTT, but hopefully our capable developers can find a way.
