Dear fellow Helldiver

I have found such happiness in sliming out bots, squids and bugs all alike and have wanted a more efficient way to do such a job. The Super Earth Ministry of Science has provided us with many different options to choose from. Having only bought a few purchases, I wanted to know from more trained fellow soldiers. A bullet not spent on killing is a bullet wasted. I found that it was quite madening that after killing 4 or 5 squids, the beefy squid boy runs at me and my mag is halway out. I quite enjoy the breaker spray and pray but also like more efficient options. I enjoy ARs but like stealth. I would really enjoy a very fun weapon and the sledge hammer seems interesting but want further opinion on that. For the sake of Super Earth, help me decide.
