Cannon VS sniper VS blast cannon

First of all, I wouldn´t use a regular cannon on a shooter (especially mk5+), you have 5 weapon slots, so you don´t need a cannon that reloads fast and deals only a "little" damage. You should rather go for weapons that deal more damage on one hit and have a longer cooldown time. Furthermore, at your infamy 4 mortars maybe work alright as ships don´t use good turbos to get out of their radius, but if you are planning on getting to 3k+ infamy, I´d recommend more cannons. A few weapons that are great on high infamy shooters are Railgun, sniper cannon, missile launcher and a firebomb would also be helpful since it adds a lot of burn damage. These are just ideas and can be changed in every way. No matter if you want a torpedo shooter, sniper shooter or whatever. You could also put a mine on your shooter, but as I said, I´d not focus on mortars, these become a bit useless at higher infamy. Hope it helped (btw you should check out this video: ) Porthos really explains it well and you can learn a lot by just watching
