But first know that only one of the BFG damage effects are increased with the Quad Damage power-up: the Detonation Blast Effect.
Detonation Blast Effect
BFG Effect Example and Explanation
The most obvious effect is the impact effect. If
the green ball hits a target, the target will most likely perish. This
damage effect also carries with it a radius blast that is half as damaging
to the shooter as it is to the target.
The next most obvious effect are the laser beams that burn out from the green ball as it flies through the air. While the green BFG ball flies towards it's target, it will actively seek nearby enemies and cook them with a green laser beam that is drawn from the ball to the target. That beam does 50 points of damage per second in 5 point increments.
The beams will only burn targets within 256 game units
from the green ball. 256 units is about 20-25 feet.
A large radius damage effect occurs very close to the detonation point of the green ball. This is there to keep you from firing the weapon directly into a wall or floor. It's radius effect works roughly similar to the rocket or grenade's radius effect, except the BFG does more damage.
In the source code it dictates that the shooter of the BFG will take half as much damage from the blast radius effect as any other target would. This is often referred to as the 50% rule: shooters take only 50% of normal blast radius damage. The radius effect is enough, however, to destroy an unarmored shooter who fires the BFG directly into the floor or wall at point blank range. This is designed to discourage shooters from detonating the weapon quickly to help balance it's most effective usage.
The radius effect damage is 200 points.
This is the serious damage from the weapon. It's somewhat difficult to understand, but later I'll provide some examples of how to test the weapon's effect yourself to fully understand its inner workings.
The basic concept is triangulation. In order for a target to receive the detonation blast effect (up to 500 points of damage in single play, 200 in deathmatch) a line of sight must be able to be drawn from the target to the BFG detonation point and from the target to the player that fired the BFG at the moment of detonation. If any solid level geometry blocks such a line of sight from either object, the target will take no detonation blast damage.
It does not matter what direction the player or the target is facing, and the shooter does not need to be able to see the detonation point. In fact, the shooter doesn't even have to be actually looking at the target. As long as a line of sight can be drawn, it'll cause the damage.
Blast damage total is exponentially related to the targets distance from the detonation point. The farther a target is from the BFG impact point, the less damage will be sustained.
Furthermore, relative position only matters for calculating
total blast damage, not whether damage will be inflicted.. An opponent
who stands behind me as I fire the BFG away from both of us towards a distant
wall will be sufficiently cooked from the detonation blast if neither player
moves before detonation.
Also note that all of this assumes that the target is within 1000 game units of the detonation.
As with the BFG in DooM and DooM][, a dead BFG shooter
will kill any legal targets as long as line of sight isn't broken. It is
possible to fire the BFG, die and remorph within sight of the BFG detonation
point and your old dead body. In that case
Nope, as long as a Line of Sight line can be drawn between from the player and the impact point to the target, that guy is toast.
For each of the different effects, there's a different
strategy that helps to avoid damage. First, you should attempt to
avoid getting hit with the actual green BFG ball.
Yes. Try this: Instead of firing the BFG towards
your opponent, do a quick 180 degree mouse flick and and blast it into
the floor behind where you were originally facing. If you continue
to use your movement keys to drive you in the direction you were originally
heading, you probably won't take any radius damage from floor impact and
the transaction will occur so quickly that your target won't have time
to get clear of
Another trick suggested DarkLegacy[TB] of Clan Thunderbunny is to fire the weapon directly into the ceiling of an open room that contains a target or two. The result, of course, is that any target with a line of sight to you (as the shooter) will most likely also be exposed to the BFG impact point on the ceiling and thus be cooked.
In general, however, it seems the best strategy with the
BFG 10k (As Tony Fabris, author of the Doom BFG FAQ suggested) is similar
to that of the old BFG. Detonate it
It is possible to use the BFG's blast radius to perform
a "BFG jump". Like "rocket jumping" the technique involves using
the imparted velocity of the weapon's explosion combined with a jump to
boost yourself higher into the air than possible with an regular jump.
the technique is best performed by firing the BFG directly into the ground
below your feet an instant after the jump button is pressed. Using
a BFG jump will give you a slightly higher jump than with a rocket jump.
