You have a Choice

You choose either join Eggman's Empire or Blitzo's I.M.P and both pay in IOU's but you either be in a busy ass building or a cool ass base in space

With Blitzo you live in a building however you can kill people and eat corpses all day without shame nor remorse but get yelled at

Or a cool ass base and risk getting your neck snapped by Metal Sonic and risk oil stains on you 24/7
