Code:
[RAIDER] ; land raider
Voxel=yes
Remapable=yes
Cameo=BFRTICON
AltCameo=BFRTUICO
PrimaryFireFLH=-9,-65,5
AlternateFLH0=-9,65,5 ;second sponson
A quick copy&paste; the last two lines define the firing points, with the first shot coming from the primaryfireflh, and the second from alternateflh0.
Obviously this only works on a burts=2 weapon, i have no clue how it would work when you'd use higher bursts.
