Wasn't this possible at one Point a few years ago? Definetly saw some videos od People Planting weed Plants under Bridges and such, if this was to return maybe it could be ballanced for the weed Plants planted outside of labs to grow a little slower then those in the labs. It would devide players to those not in a gang that plant outside of labs and those which are in a gang and collect Plants from Labs.
Adding more stuff to the crim side would definetly spice things up not only for the crims but the whole server as a whole.
Some ideas I have are :
BAGS - People could place them over Peoples heads to add to Kidnapping roleplay, People with bags over their heads would be blinded by a bag texture or something, and their movements inverted.
More use for trucks: At this point on the server trucks are used either for moving furniture or freelance Jobs. It would be cool for criminals to have more use for trucks, either by transporting some sort of material that could aid them or transporting weaponry for whatever reason. Trucks definetly have more potential to be used by Crims if some stuff were to be added.
