The Division 1.5 Update will roll next week which will bring a lot changes and fixes for the game and with it will also come the Survival DLC which will change the way you play by spicing things up with new mechanics. While PC and Xbox One update will roll out on November 22nd, PlayStation 4 update will roll out next month

Gamemode Survival

2 game modes PvP Survival OR PvE Survival – Groups can meet on the map and help each other but not kill each other in PvE mode.
PvP mode gives you 20% more points for your final Survival score that gets transferred into sealed caches
24 players on the LZ map
WHEN YOU DIE ==> GAME OVER! (you can be revived from the downed state)
hunger, cold mechanics
There are Landmarks on the big map – but the mini map is deactivated
you are sick and need to extract yourself
you start with a pistol only and with no / bad gear
clothings have a ‘cold’ rating that protect from the blizzard
crafting plays an important role
there are ‘hideouts’ – like apartments (those are not safe house)
there are crafting benches in the hideouts
you need to build a new mask / virus filter when you want to enter the DZ / contaminated zones
on the borders of the map the enemies are weaker and get stronger when you move closer to the center of the map.
No need to be L30 to play Survival – Just need access to the BoO
No link to World Tier – every player plays as the same difficulty level (you start with a simple green pistol) and work your way up.
