Always group your ships when attacking (use 'Alt' and '1-9'). To select ships, either click and drag or select 1 ship and hold on the shift key and select more.
Then, make sure your groups are full and get loads of groups. Rather than get 2-3 big groups, split them in half if you want to so you only have 4 in a group and have about 5-6 groups.
Science Ships (Nebula, Shadow ect.) cannot use their special weapons if grouped with other ships not of its Class.
Ships that are not Science ships and have only 1 special weapon can be grouped with one another..!
