where can i get grand theft auto 5 on my ultimate game pass?

1. The original Grand Theft Auto (with top down view)

2. Grand Theft Auto Vice City

3. Grand Theft Auto - San Andreas

5. GTA 5

Is there any way to play it on Xbox?

That game is not currently included with Game Pass.

If you purchase a game, it's yours forever. You don't need a premium Xbox Live Gold subscription for that. That said, if you're talking about the Game Pass Ultimate offer, any game you download through Game Pass Ultimate will require that you maintain
that subscription.

Let's say you purchase Grand Theft Auto V on a sale. You bought the game, so you own it. Now, conversely, let's say you use Game Pass to download Gears 5. If you don't renew Game Pass, you would lose access to Gears 5, but would still be able to play Grand
Theft Auto V. However, if you don't maintain an Xbox Live Gold subscription, you cannot play online multiplayer components of GTA5 … but you can still play any offline modes in the game.

The time you will be banished into a bad sport lobby is really based on how much you managed to annoy/destroy other players items or experience in game.

Bad Sports

The main known factors that contribute to Bad Sport status:

• Destroying other player's personal Vehicles appears to be a key factor in being designated a bad
  sport. While killing a character appears to be penalty-free, wrecking cars owned by other players is an easy way to get blacklisted.

• Dropping from Jobs mid-mission is
  a sure-fire way to get labeled a bad sport. Rage-quitting or stepping out of online matches has a direct negative effect on your sporting
  status.
• Getting reported for annoying players and griefing.
• Getting voted out of Jobs.

The first Bad Sport designation reportedly lasts two days with subsequent banishments increasing duration of time in
bad sport lobbies.

The opposite of a GTA Online Bad Sport is a Good Sport who gains a reputation for
fair play and relative courtesy. Good Sports will also receive cash rewards and discounts periodically for their behavior.
