Cachette: Fight through a secret hideout next to a French rail terminal packed with shipping containers, rooftops, and compact interiors built for constant flanking.
Lotus: Deploy into a battle-scarred Korean fishing village where narrow streets, burning buildings, and abandoned armor create varied engagements from close quarters to long sightlines.

Expect an explosive tank battle, legendary loot, action across the ground and air, and other surprises to find during your matches.
Every Loadout has room to dominate and are default for the Beta. Choose from AR, SMG, LMG, or Sniper Default Loadouts. Close-range Operators can weave between buildings and through the center of the facility, while longer-range Loadouts benefit from rooftops and elevated windows overlooking the facility’s points of interest. Beneath it all, an underground tunnel network offers another way to rotate, flank enemy squads, or briefly disappear before launching your next attack.
Stay frosty: We'll see you in the Beta.
