There are six different airships in the game varying in size, armor, speed, weapon loadout, and maneuverability. Smaller ships like the Goldfish have less armor and weapons but fly and maneuver faster compared to larger ships like the Galleon which is very slow but has the highest armor and largest weapons. Each ship has its own pros and cons, and it basically boils down to your preference, team strategy and weapon loadout selection.
If it wasn't for the sale on Steam, I wouldn't have come across this game. Sale of $9.99 ends May 22! It's totally worth! See you aboard!
