That doesnt sound at all like BR to me, the key feature of BR is that its a last man(squad) standing mode. Thats the very definition of BR. Theres nothing in the description above which makes any mention of last man standing. In fact, the games Post Scriptum, Squad and Hell Let Loose fit the description of squad based gameplay where good comms are needed and sweaty palm tension building moments and none of them are in any way BR. That description doesnt sound like BR to me, not without the last man standing feature, without last man standing it quite literally isnt BR. I suspect folks who desperately want a BR mode are reading too much into it and will be disappointed
The rumours I've heard are that its going to be a mode similar to Escape from Tarkov, which would make a certain amount of sense, fits with the Hazard Zone name and would be a squad based high stakes mode where good comms is vital.
