@Su-tehp: TLDR when you want to make some Shivan SRBC just take one of the Mjolnir beams, color it red and don't use any custom unbalanced stuff. 
Hmm, a red beam coming out of a turqouise Terran-designed RBC...those two colors just clash with each other.

(Not to mention that red-blue color-blind players won't even be able to see that awesomeness.

)
Unless you mean take an SSG Annihilator and make sure it's equipped with a red-colored Mjolnir beam. If that's what you meant, then I heartily approve.

EDIT: I just realized all the custom Shivan sentry gun mods all have multiple cannons, not a single large beam like the Mjolnir. And a reskinned Mjolnir with a Shivan skin would be a cop-out as well as too angular and Terran-looking a design for the Shivans.
