http://infinitythewiki.com/en/Saturation_Zone how saturation zone works in this case ?: 1: both are affected (like smokes) 2: none (LoF outside the SZ) 3: only active player (because he shot "from" the SZ)
Active player is inside the zone therefore both attacks are affected. http://infinitythewiki.com/en/Special_Terrain_Rules#Visibility_Conditions Any trooper in base contact with a Special Terrain zone, or whose base or Silhouette Template is covered at least partially by Special Terrain zone, is equally affected by the Effects of the zone
Both are affected. As you yourself linked to, for Saturation it is "from, into, or through a Saturation Zone" What's left to fill in is found here (added emphasis): http://infinitythewiki.com/en/Special_Terrain_Rules Any trooper in base contact with a Special Terrain zone, or whose base or Silhouette Template is covered at least partially by Special Terrain zone, is equally affected by the Effects of the zone.
