I had an idea for a Mafia themed Warframe that would have existed during the creation of the Corpus.
They would be similar to Mirage in the sense of making Doppelgangers, but the Doppelgangers purely exist to help provide CC instead of extra damage.
The Mafia would treat fellow Tenno like family, giving them various damage buffs and would get really pissed if one of their family members dropped.
I also had some kind of unique currency that they would have to collect from enemies to be able to use these buffs.
Also they would have came with a new Tenno themed Metal Bat with nails poking out of it.
For consistencies sake, the new grip type it uses would be officially named "Club."
