Wait hang on closed beta testing, so like how pre ships were ?
"Very soon, a large-scale closed beta test of infantry will begin. We’ll share more details about the tech trees, weaponry, gear, and gameplay features in future devblogs. "
I mean, as far as we know the event could not have any WW1 content whatsoever. We have a trailer showing modern day stuff and the trailer usually was the thing that “teased” the event gameplay.
The announcement talking about WW1 content could mean that either the announcement, the trailer or neither of them are red herrings (wouldn’t be the first time they hosted two april fools modes)
It seems like its not an April fool it looks like a Closed Beta test like they do sometimes for example with the France Navy or Swedish ground forces Tests
