It’s definitely Overwatch, but third person, so a bit of Smite in there. The third person, art style, and of course Marvel IP make it stand out in my opinion. I’m excited to give it a try!
These skins do not carry over to the full game and are just examples of skins that will be in the full release! The only thing from the Alpha that carries over to release is the Scarlet Witch Alpha skin (the white one you can see in this video), a spray, and a banner.
If you have access to the closed alpha (got a key and are able to play right now) you have until the end of the alpha on the 20th to hit level 30 on the Galactica pass, you’ll see it on the menu of the game, and that will give you the skin permanently to your account. You can scroll through the pass and see it there. Best way to progress is by doing the daily+weekly challenges they have there, and there will be a new batch of weekly challenges coming in a few days, halfway through the alpha. Just play and you should get there!
