11 and 12 are BS heavy slots , they fire in all directions except up .
13 is BS light , it fires in all directions except extreme down and extreme front .
3,4,9 and 10 are Cruiser heavy slots , rest are Cruiser light .
Mount BS Primaries ( or BS Pulse if you use them ) on 11 and 12 , mount BS Light on 13 ( you can also mount flak , but CM is enough for torpedo's and Missiles ) .
9 and 10 are perfect for Light Mortar , since lower one ( slot 10 ) fires in all directions except extreme up , while top one ( slot 9 ) cant fire down and extreme rear ( and you can also mount third Cerberus or Gatling Solaris there if you decide to have only one LM .
3 and 4 are placed left and right and they fire in all directions except opposite ( right and left ) . On them you can mount Cerberus ( or x2 Cruiser Missile ) for anti capital or Solaris Gatling Cruisers against snubs .
On rest also mount your preferred weapon , Liberty Cruiser turrets or Solaris Cruisers .
Personally , i like x2 BS prims , x1 BS Solaris , 2x LM , x2 Cruiser Missile , x6 Solaris Cruiser .
