In the Only War Core rule book on page 173 for the weapon quality scatter it says the following:
"The standard ammunition of these weapons spreads out withen fired, hitting more of the target. If fired at a foe within Point Blank range, every two Degrees of Success the firer scores idicates another hit. However at longer ranges this spread of small projectiles reduces its effectiveness. All Armour Points are doubled against hits from Scatter weapons at Long or Extreme Range."
On the GM screen for scatter it lists the following:
"At Point Blank Range, weapon gains +10 to hit and deals +3 damage. At Short Range, weapon gains +10 to hit. Any longer ranges, weapon suffers -3 damage."
As both of these versions of the scatter quality seem to be handled a bit differently from each other I was wanting to know which one was the indended one the game was going for.
The one in the book seems to have much more of high to low damage range if you get into point blank range as you could get multiple hits, but it also doesn't say a limit of how many extra hits you could score.
The one from the GM screen seems to have a less high damage total but at the same time less of a damage penalty at longer shooting ranges.
