Thank you for the review @soldierofdreams!

Have you tried the 2nd and 3rd level? If you don't have the characters/weapons for those levels you can still try them in free-to-play mode (but you won't earn).

As a thank you for your article/video, here is a PVP pass!

For the alpha stage that's all you need to start playing against your friends (or bots if there aren't active players in your region) and earn DOOM and HIVE!
