If you’re looking to go up in Sims 4 on Xbox One, there are a few things you’ll need. First, you’ll need a ladder. Second, you’ll need some Sims 4 tools. Finally, you’ll need to be able to access the upstairs area of the game. To start off, first open up the game and find your Sim’s house. Once you’ve found it, head inside and use the ladder to get up to the upstairs area of the game. Once you’re in there, use your tools to fix some of the broken objects and then use the door handle to open it.
