Do you filter your Steam Library with games that are installed versus games that you own? Is the word “Games” displayed to the right of the Search bar in your Games Library? If not, click on the word displayed and select Games to show all the games in your Library. From here, you should see Planetary Annihilation: TITANS on your list.

It may also be the case that your Steam account is not linked to the PA account that your Kickstarter information is on. If you’re not sure, please open a ticket at https://support.planetaryannihilation.com/ and we can make sure your Steam account is linked to the correct account.
