Guys do we need to pay to get access to other campaigns …I mean we need to pay for dlcs/campaigns ?
No. Everything should be included, right now this is an Alpha test for the Battle of Moscow campaign. All the other campaigns are locked until the devs say so.
I think everything will be free, originally the business model for this game was not going to be free to play, and you were going to have to buy each game separately. The devs then held a vote and most people voted for a f2p model, problem is they never updated that section of the FAQ that talks about separate campaigns being paid for.
are you sure that the devs did not update their FAQ?
Nope, this is still on their faq
"That’s why we have decided to make access to these battles independent of the other - each campaign will be a separate game. However a player who purchased more than one will see them all in the game as selectable chapters. Also we do not want to impose micro-transactions as an opportunity to purchase some sort of ingame advantage. A player will have an opportunity to get collectable weapons and characters that are different from the others but do not offer ingame advantage (which is strange in the first place - a bullet to the head means death for every person after all) rather providing uniqueness or rarity. "
The devs have already announced that they wont be using a pay to play model for each chapter and will instead make Enlisted free to play, they never changed this FAQ entry though.
