Actually X-Morph: Defense Complete Pack. SteamDB

So you'll get all the DLC and the soundtrack.

You may enter the giveaway if you are missing any of the DLC or the soundtrack.

Since it's a DLC, people who own it might be able to enter. The winner will need to accept my Steam friend request to check that they don't own all of the DLC and the soundtrack. No judgement, mistakes happen 🤷‍♂️🤷‍♀️🥴
