When engineering on a goldfish, the turning engines are often forgotten, keep an eye on your surroundings and split the work load with your fellow engineer by communicating who will repair what in the lobby or at the start of the match.
Double gunners will struggle to keep up with repairs and bring very few benefits to the ship, it is better to have an engineer dedicated to shooting. Though he shouldn't forget to do his repair cycles on reloads!
Damaged guns do less damage, keep it repaired!
Communication and cooperation are the keys to success! If you're unwilling to communicate with your team and co-operate with them, even on a basic level, you can only expect to loose.
Chem spray is very powerful against fire weapons, assuming you don't forget to use it before taking fire.
Guides and hints and tips do exist, don't be afraid to read a bit, it gives you something to do while in Match Maker.
Crew should always check what their pilot intends to bring in the lobby. Pilots should always tell their crew if they are going to change ship! The last thing you want is a gunner loaded out to shoot a mine launcher when you're bringing a heavy carronade!
Pilots should communicate and agree on targets. Try to prioritise the biggest threat or fastest kill, depending on your ship loadouts.
If someone in the lobby is telling you "that's a bad idea" they're not insulting you, they're trying to help.
Being stubborn about being a gunner does not make you look cool, it just leads to being blocked and pissing people off. Its better to make friends and cooperate with the people you're going to play with rather than loose hope of making friends.
Winning is fun, but its not everything, some of the most fun matches come from being in a lobby with friends and being silly. (Munkers only, galleon only minotaurs, harpoons only.) so make friends in this awesome community!
Racism is never acceptable, regardless of what colour you claim to be.
Creeping girls will never get you laid or make you look like a man.
Let your team mates communicate their plans, we all like a chat but sometimes too much talking can make it harder for your team.
Don't be mean to newer players who may be learning, there is a difference between a learner and a fool.
Pilots should consider the difficulty of their weapons when loading out their crew. If you have a crew of newbies who have never shot Hades and Lumberjack before, consider wether you want to get a win or give them a taste of the tough guns.
And on the flip side
Practice mode is great for practicing those hard to shoot guns if you've never shot them before, don't be scared to use the practice mode to learn the guns so you're not un-prepared. After all, practice makes perfect.
