At the moment, there is only 1 option: the default OG broom closet bridge.
Please Cryptic, the S31 Intel Sci ship has a long list of bridges to choose from, why leave the heavy battlecruiser out in the cold when it comes to choosing a bridge? Its one of the nicest ships in the game and y'all put so much time and effort into making that ship as savage as it is, but the fact that we are stuck with ONE bridge is...frustrating and sad. With a long list of bridges to choose from, who knows? I might just splurge on a 2k Zen bridge.
Fingers crossed for the return of the Section 31 Heavy Rifle
