# What are Oxygen Credits?

> Oxygen Credits are a balance you receive when someone takes over your habitat, equal to its value before the takeover. Spend them on any claim or takeover in Mars Move-In. They can't be withdrawn or exchanged for money.

## How you get them

When your habitat is taken over, its value before the takeover is added to your Oxygen Credits and you get an email. Your balance shows in your account panel on the map.

## How to spend them

At checkout, credits are applied first and you pay only the rest. If your credits cover the whole price, the plot is yours without opening Stripe.

## What they are not

Credits aren't money. They can't be withdrawn, transferred to someone else, or exchanged for cash, and they may end if the service ends.

## Key points

- Received when you're taken over
- Worth your habitat's value
- Spent at checkout on any plot
- No cash value

## Common questions

### Do credits expire?

Not while the service runs.

### Can I give credits to a friend?

No, they stay with your account.

### Do I get credits for a Founding Habitat?

Founding Habitats had no owner before their first purchase, so no credits are created when they're claimed.
