On the main campaign screen, select Office, and then the Assets option.

A lot of these can be bought initially, but will cost a lot. The reason why I have not added pricing is because they can change with one of the entourage upgrades, and it changes a lot. For the better.

Others will show up later, for example, the Modern Lamp requires you to buy the Table Lamp, as it's a direct upgrade. Some of the followups that go 1-2 or 1-2-3 also require you to buy the lower number first.

A bunch of these are only available through other means, however.

• Piano: Can only be obtained after getting a goal regarding the piano.
  
• Torini 3000: Can only be obtained after getting a goal, and doing a mission at the DMV.
  
• Red Star: Can only be obtained by finishing Ranger's story line.
  
• Dragon Dogs: Can only be obtained by doing the Dragon Dogs big heist, and KEEPING the statues! (Don't sell them to Khan!)
  
• Gold Treasure: Can only be obtained by doing the Gold Cup big heist, and KEEPING the gold! (Aka, don't give it partially or entirely to Dollar Dragon!) - Also, this is a DLC ONLY ASSET.

For the ones that require you to make a choice to keep, after doing it once they will be permanently in your Office Assets list, and you can choose otherwise in future runs.

You can always comment below- who knows if they'll add more assets over time. The Gold was originally not there either.
