Ghostbusters: Spirits Unleashed Ecto Edition

Contracts are located in the Side Hustles menu, to the left of the Find a Job option.

These are accumulative challenges grouped in sets of threes and it seems you can only have 1 contract active, if you change the contract you lose any progress made so far.

I chose to go for "Ghost Trapping Basics" first which includes Trap 5 ghosts in your trap, throw your trap for a total of 750 meters, and trap 1 ghost by yourself. Again, these don't have to be in a single match, you can check your progress during a match by pressing back/select. These can all be done in solo matches with bots.
