Hello Space Pilots,
Are you having difficulties remembering which ship you put in which hangar?
There is an extra special bonus for premium pilots to help them keep a step ahead of the enemy in the heat of battle: customized names for hangars.
Use personalized hangar names to aid you in stressful situations. If one of your hangars contains a Goliath, then give it a similar sounding name! Make the hangar and ship names memorable for the intense heat of battle.
Your new names will appear on the space map in the tool section and you'll be able to quickly select the right battle cruiser for the right battle in the warp section.
Just click the hangar name to the upper right of the hangar and rename your hangars!
