Special Values:	none
Default:	no
Applicable to:	Projectiles

This flag determines whether this projectile can be stopped by walls in its path. If set, the unit firing it will only fire once it finds a firing location not obstructed by walls.

Mind that IsLaser=yes weapons with warhead set to Wall=yes will be able to fire over walls even if this setting says it shouldn't.
