A new map has been added in the latest update (1.5.15).

Overgrown: Large overgrown rural map with multiple buildings!

A few other updates:

• New multiplayer challenges
• Heli Sniper has less sway, making accurate shots easier
• Dragonfire now has same damage drop off as SMGs
• Destroying enemy equipment now earns XP
• Updated grenades so they don't bounce/roll as far
