When in the vault after selling Rocket, players will need to find all the highlighted bowls to get 12,000 units. There are also choices in Chapter 4 for selling Groot or Rocket that can lead to more units.
The amount of units players have to spend will depend on decisions made earlier in the game, such as who players chose to sell to Lady Hellbender. Unfortunately, buying the ticket may not be worth the steep price, especially for players that want to keep their promise and pay the Nova Corps fine later on. The ticket can be bought when players travel to Knowhere in Chapter 6, and it costs 1,000 units.
Marvel's Guardians of the Galaxy features the ability to purchase a lottery ticket that has a jackpot worth five million units.
