The true challenge for a d20 Modern campaing is the balance of power with the modern weapons. A psico-killer with a knife may be a nightmare for unarmed civilians PCs in a survival story, but for a PC like Silverter Stalone in the movie "Cobra" they are only walking target, canon fodder and free extra XPs. A huge monster like an elephant can be killed with only a shot by a RPG (Rocket-propelled grenade). A horde of zombies is a serious menace, but they could be hit by means of driving a truck. We need a system to give the right reward of XPs. If firearms are too powerful no player will want a hand-to-hand warrior or archer, but all to be gunslingers.
this is somewhat true but look at some of the old adventures where kobolds were used to be the main antagonist. The key is to the use and the environment that the attacker is used in, as to a human killer with a knife. He would stock and attack when he can get an advantage over the prey he is following. The lead up and investigation and finding the killer is the adventure and facing said killer is a final show down. But the added twist would be that the killer infact knew he was coming and had prepared ahead of time, Traps and stuff. The key is to not fight streight out and to wittle the person down or have them hurt them selves.
