You're thinking about it wrong. You start with 4 shots every 10 seconds for FREE. If you find a BL2, you don't need to upgrade your weapons system and now you have 5 shots every 12 seconds. Or even better, find a Flak 1 and you have 5 shots every 10 seconds without having to upgrade weapons. If you DO upgrade weapons (at your leisure because it's not critical to success) you always have another shot.athorist wrote:Yeah, but it's really inefficient to only get 4 shots from 4 power bars. I found a hull beam, but because I only had 3 other shots, it's not very reliable against 2 shield layers.
When you find a Glaive Beam, it's hard to buy 3 weapon slots and 3 power bars to get it going on most ships. On the Red Tail you can keep upgrading weapons one bar at a time, shuffling your weapon around and using the basic lasers as filler.
Oh, and there's a LOT to be said about fully leveling up your weapons officer in a single sector.
