bfg for modern d20?

basically trying to figure out how you'd do a weapon that requires a strike to hit yet have a minor blast radius, like the bfg from doom, and just trying to figure out how you'd do it ruleswise.

Why not treat it the same as direct fire with a grenade launcher?

M79

This simple weapon is a single-shot grenade launcher. It fires 40mm grenades (see under Grenades and Explosives, below). These grenades look like huge bullets an inch and a half across; they can’t be used as hand grenades, and the M79 can’t shoot hand grenades.
Attacking with an M79 is identical to throwing an explosive: you make a ranged attack against a specific 5-foot square (instead of targeting a person or creature). The differences between using the M79 and throwing an explosive lie in the range of the weapon (which far exceeds the distance a hand grenade can be thrown) and the fact that the M79 requires a weapon proficiency to operate without penalty.
The Exotic Firearms Proficiency (grenade launchers) feat applies to this weapon.

Minor blast radius???

But the way you do it is like the M72A3 LAW

BFG 9000
The BFG 9000 (Big ing Gun) is a man portable energy weapon, not totally dissimilar in use to a rocket or grenade launcher. It comes as a large, almost boxlike metal gun with an assortment of metal tubes and pipes on all of its surfaces along with numerous lights and on some versions, a HUD showing the amount of shots available.

When the BFG is fired, a luminescent green ball of energy is shot from the gun. When this ball of energy hits a target, it explodes like a grenade or other explosive, dealing its 10d6 points of damage to all creatures within a 20-foot radius (those in the area rather than those struck by the attack are entitled to a Reflex save DC 18 for half damage).

Because of the peculiar energy emitted as part of the explosion, the BFG ignores up to 10 points of hardness of vehicles, buildings and other objects within the burst radius.

The BFG has a recommended minimum range of 30 feet. If fired against a target closer than 30 feet away, the firer may be endangering a very valuable weapon.

The Exotic Firearms Proficiency (rocket launchers) feat applies to this weapon.

I took the grenade route for my BFG mod, but added it did damage to every biological creature in the room that wasn't equipped with a ID tag. The tags kept the 'bio-feedback' part of the gun from recognizing the good guys as living things.

I think it was in Quake 2 that the projectile shot out smaller projectiles at other creatures, and I used that as my model.

Pfft... You call THAT a BFG? You don't understand the BFG at all!

The BFG's behavior is a bit stranger than that...

First, the energy ball shoots out. About half a second after the ball explodes, 40 invisible streamers are fired again from the person holding the gun, in the same direction the ball was originally fired in, but if the person has moved since then the origin of the streamers moves along with him.

Now try and model THAT, d20 modern! pfft

(if you're curious, the streamers are invisible because of performance issues when Doom was originally created)

A cone fired in the same direction the gun was fired in.
