DICE are keeping this to themselves for the time being, so all we know is as follows:
Dataminer Temporyal has been through the recent Battlefield 2042 closed alpha and found references to persistent gear and permadeath, with Escape From Tarkov working something like a roguelike where if you die you lose all your equipment.
There donβt seem to be any unique maps for the mode but Temporyal has found evidence of Orbital β the map from the technical test β having a specially modified version for Hazard Zone β which is likely to be true for other maps as well.
Both Hunt: Showdown and Escape From Tarkov are PvEvP games, which means you fight both other player characters and computer controlled enemies. This appears to be the case for Hazard Zone as well, including Tarkov style boss characters.
Uplink towers will allow you to call in help, like an ATV or robot dog, but enemies can also radio in for reinforcements.
The goal of Hazard Zone seems to be collecting data from crashed satellites and other devices, although completing the mode appears to work more like The Divisionβs Dark Zone than it does Tarkov, with the ability to call in an evac helicopter.
