Just remember you will be able to play her if you preorder the game…
I’m not a fan of preorder bonuses that split the community. Here, with the example of Tekken 7, only people preordering the game will be able to play Eliza. To promote this bonus, a dedicated gameplay trailer was released:
Tekken 7 is set to release on June 2nd on PC, PlayStation 4 and Xbox One. Everyone, who preorders the game, will receive a code for Eliza. As for now it’s unknown if players who decide to buy the game after the release will be able to get her separately.
The base game should include 20 characters, with additional 17 added via DLC in various forms (e.g. season pass, as you may guess).
