[2021] Officially Confirmed. You can play all BF2042 maps and weapons as NO SPECIALIST (2042 Faction) with progression.

Correct, you can mix and match. And that's a major part of the fun!

I'll quote the relevant bits from the latest Battlefield Briefing where it's explained in detail:

Characters"Depending on what you chose in the previous section, you’ll then be able to deselect which classes (or 2042 Specialists) are playable. You’ll also have the options to denote which factions show up in-game. The UK, US, and German factions are available for 1942, with the game appropriate versions of the USA and Russia available for the rest."

Weapons:"In total, there are over 75 Weapons available across the entire experience of Battlefield Portal at launch. Now that you’ve chosen your factions, you’ll have the ability to manage what weapons are available. If both teams are from the same era, you can also make use of our unlink teams function to customize exactly which weapons each team is gaining access to."

There's a ton more detail in the blog, so be sure to check it out:

Since we are so close to (Early Access) launch, I think part of the fun is also to leave some questions unanswered so you can start discovering for yourself when you jump into Portal.

We've detailed quite a lot of the available options already, but I encourage you to check out the Battlefield Portal website when it launches, and browse and play around with the different options.

As mentioned, you don't need to own Battlefield 2042 to start creating experiences on the website, just login with your EA account and you are good to go.

Lastly, as soon as as the website is live we'll let you know because we understand you are eager to jump in!

9 more days. you got dis.

Yes, within Battlefield Portal you can mix and match.

There's just a ton of options, and I hope you'll have fun checking them all out :)
