Will Resident Evil 7 Biohazard have multiplayer? The short answer is no.
The Resident Evil games have not historically relied on any kind of multiplayer feature and so it would be a surprising change for Resident Evil 7 to announce multiplayer.
No online store pages or ratings sites have announced any sort of Resident Evil 7 multiplayer and if there is any sort of change to this before release in two weeks time it would be very surprising.
Another hint towards Res 7 not having multiplayer is that the game will not be any near as action orientated as previous installments of the series. This time around Res 7 will be more of a survival horror game with limited combat and more running and hiding, something that won’t really transfer effectively over to any kind of multiplayer game modes.
