It's unfair when 1 of your teammate leaves for some random reason. It gives you a pretty large disadvantage... To make things fair, the one who leaves will share it's health with the remaining teammates. Thus, if player A leaves with 48 hp, then player B and C should get an extra 24 hp. Rate this + so the creator can see this!
You should not focus on weapon and fire rate only. You should try to get upgrades that gives at least 4 or more bonuses. The flags are very great for this. Having all 4 flags gives you a very powerfull balanced ship. Adding the weapon +4 will even give the ship maximum attack, making it the most powerfull balanced ship. With both max weapon and high fire rate, enemies will fall really fast. Having a high speed will enable you to dodge bullets easier. And higher loot + magnet will let you earn cash faster, which is very good for the hard badge. Hope this strategy will help you guys out there ;)
"I've come to all your kind of restaurants. I've seen all your burgers, pizzas and tacos, and they are all the same. The ingredients are always a few centimeters from were I want them to be. Again, this cherry is 1.5 centimeters from the perfect spot, so I will lower the tip with 17 cents."
The Morning Star isn't the only strongest weapon. The Razor Sword has the same strength, but the Razor Sword got 3 defense and the Morning Star got 3 magic. To get the Razor sword: Combine a wooden sword with 5 Iron Globes.
To make things easy, try to maximize all stuff before upgrading rectorate to level 5. This let you get the full week to build, train and make proper starting cities (you probaly got the second city by then)
