Ah yes, Silversun Strip, a place that contains more things (possibly) to do than every other area in the accessible areas of the Citadel combined, that is, if were talking about ME3.
SCENARIO: Whatever the hell you want, as long as you were able to do it in game.
Examples: Armax Arsenal Arena, Castle Arcade, Silver Coast Casino, and that bar within said casino.
All of my OC's are available for you to RP with, or, if you want, Shepard or any of the crew of the Normandy could be there instead of my OC's.
