Battlefield 5's battle royale mode is scheduled to release in Spring (or Autumn in Australia), which means it could arrive any time between now and the end of May. But according to new in-game evidence, it'll probably end up coming sooner rather than later.

In what could either be a mistake or a tease, a recent Daily Order challenge lists playing Firestorm (the name of the mode) among its tasks. That's obviously a bit hard, since the mode isn't available yet. Specifically, completing that Daily Order challenge requires scoring 500 points in the mode.
