Hey Brandon. I'm an experienced music producer/composer and would be happy to collaborate. I have a little sound design experience (I'm currently getting an MA in composition for video games), but I wouldn't say I'm as confident in that skill :) That said, I would still be happy to design some shooting and explosion sounds for you.
I made these retro game demos a while back. I think my song "Berserker Energy" fits the vibe you're going for. Give it a listen here
You can listen to more of my music on my website or on my website
Connect with my on Discord if you want to talk more, I'm kip_lavie
