While not Multiplayer, might I suggest people that haven't tried Shadowrun: Returns, Shadowrun: Dragonfall, and Shadowrun: Hong Kong give those a shot. They're all on Steam, and are by Harebrained Schemes, who licensed the video games from Microsoft.
Microsoft owns the rights to Shadowrun as a video game. Topps owns the rights to Shadowrun as a Tabletop game (and CGL licenses it from them.).
If you're into Retro Gaming, there is also the SNES and Sega Genesis Shadowrun games.
And for my next trick, anvils!
