The Last Stand expansion gives you access to a new game mode
and a new incursion
Last Stand Game Mode
To access the Last Stand game mode, you'll need to find the entry point in the Base Of Operations.
This will be located next to the Survival entry point. To be able to access it, you will need to be level 30 and start the side mission Operation Last Stand
by talking with Kekich.
Once you initiate the Last Stand game mode, you'll be taken through a quick explanation of the game mode. Here's an overview of what to expect:
. 8 versus 8 PvP combat
. Fight to control three key tactical locations on one of 4 Dark Zone maps by occupying the locations and scoring points
. Fortifications and SHD tech tactical boosts to activate and win victory for your team
Incursion - Stolen Signal
The new incursion will pit you against the Rikers in a TV Broadcast building. You'll find it on the Map of Manhattan, in the Clinton District. Note that you'll need to be level 30 and have access to world tier 2 to be able to start this incursion.
