Did they ran out of budget making 30? Was keeping DD running that costly or something?
None of the music search app i used can find the background music due to the noises of all the attacks going off.
Took some ideas from Orion and Sirius, Drifter is the older brother here, who have went through hell once, explained the scarred blind eye. While Operator is the younger, still depressed like Drifter, but have a more positive outlook on things....Mostly.
Both have different preference for Warframe as well, Drifter prefer pure destruction and power (Uriel, Gauss, Lavos), while Operator prefer more technical and skill based frames.
