I've been playing around with my weapon setup lately now that I've finally bumped up to the A-tier power plant. I have 2 med beam turret "fly swatters" on top and 2 lg gim pulses on top as well. I started with a lg gim pulse on the nose but I wanted to play around a little. I put hammers on the med spots and a lg beam turret on the nose but that didn't track as well as the 2 med's on the top and it all felt ineffective. Now I've put my fly swatters back on top and I added a lg gim cannon to the nose. That has been fun but I'm quite curious to see the class 3 plasma accelerator in action. Is it worth the upgrade from a cannon?
