I was joking about the rc nuke, even tho I like the idea. Just to see if anyone was paying attention.
Can you describe more what the car jammer is not doing properly? Under normal circumstances the jammer goes far enough that a player would likely get some damage from the car, if any. But it also depends on the player health setting of the server. So its a balance requiring some trial and error. Make the jammer have a bigger radius? Or decrease the power of the explosive? No real right answer to that one. Just what works best for the game.
edit: speaking of nukes, there are two types of care packages. The normal one at 4 kills has the current stuff except the highest value items like the ac130 and no tactical nuke. The second type, at 7 kills, has only lethal weapons ranging from the rc to the 130/pavelow and the nuke. Nothing passive like the uav.
