HazardZone is a Battlefield2042's high stakes game mode that releases alongside All-Out-Warfare and Portal. It involves squads landing on a map, hunting down Data Drives, and extracting.
Battlefield2042 will release on November 19 and will most notably not include a battle royale mode at launch. Instead developer DICE is focusing on a new competitive squad-based game type called HazardZone that focuses on multiple four person squads moving around a map and competing to collect Data Drives and get them to extraction points. As opposed to much larger player counts in popular battle royale titles, this game type will have 24 players (six total teams) on Xbox One and PlayStation 4 and 32 players (eight total teams) on Xbox Series X|S, PlayStation 5, and PC.
HazardZone does seem to draw plenty of elements from battle royale titles, such as the ability to spawn downed teammates back at Reinforcement Uplink points or using a Tactical Upgrade. HazardZone will be playable on all launch maps from All-Out-Warfare and will occasionally incorporate extreme weather such as tornadoes. Another large element to HazardZone will be squad makeup. Players can't use more than one of the same Specialist on their team encouraging teams to work together and rely on different Specialists throughout each match. Having mobility with an operator like Sundance might provide a key advantage during a different phase of the match in comparison to Falck's healing, for example. There is a ton more to know about HazardZone, including phases, currencies, tactical upgrades, and how to maximize points. Make sure to watch this video for the full breakdown.
