No!
Star Wars Jedi: Fallen Order is not a multiplayer game. It is a single-player video game. The game was released November 15, 2019, on Windows PC, XboxOne and PS4.
This new game does not have microtransactions and DLC as well. Star Wars Jedi: Fallen Order is also not an open world, but it has exploration and puzzles.
