Ghostbusters: Spirits Unleashed Ecto Edition

This a multiple achievement guide, but primarily this is the best way to earn Profile and Ghost XP at once.

Seasoned - Reach Level 50
Ghost Expert - Fully Level up a Ghost Class

Guide:
Go into the Ghost Realm from the Firehouse
Select preferred ghost. The starting ghost is most ideal for area damage.
Starting from the Ghost Realm should update your progress trackers from previous multiplayer games.
Start a game on Clocktower

Immediately head for the Ghostbusters entrance - Head as straightforward as possible when the round starts.
Get all the Busters together as often as possible.
- This should be easier the quicker you arrive. -

Down one Buster and the others should quickly group together to keep reviving.

Stay close and keep hitting them with RT basic attacks repeatedly
Whenever your abilities become available use each of them.

Using the area damage attacks will ease knocking them back down once they're up but you shouldn't have a problem.

When all Busters are down at once you should use this downtime to knock out as many Proton Pack Sabotages as you can. This isn't totally necessary but will result in more time to keep the flow of knocking down the busters and will quickly net you the diabolical achievement as a result.

All your attacks and tether-breaking will earn you lots of XP - Watch this stack on the left and you will get over 50,000 xp per run and huge level-ups


The Following 9 achievements can also be naturally gained in this process:



Line em' up - Pass through all 4 busters within a 3-second window
When all Busters are grouped you can attempt to pass through them here, this would be a better method than playing naturally, as I found this to be quite difficult in my normal playtime.

I don't need these - Detonate all 3 of your rifts during 1 match and still win
If you collect and drop your rifts, then detonate them with B before doing one of these rounds then you could easily net this achievement on top.
