Delta Force's Zero Dam map has been redesigned by Team Jade as part of the Season Echo update, responding to community feedback to enhance gameplay. Key changes include a complete overhaul of the elevator extraction point, adding a second entrance and reducing cover for defenders to promote movement. The surrounding areas now feature new reed marshes, swimmable channels, and an underwater area, with birds added to reveal player locations when startled. A new task chain, 'Operation Gold,' involves players accessing a vault while managing hydrogen gas filling the room. Horn-shaped mounds inspired by local legend provide opportunities for loot and personal messages. The update also includes quality-of-life improvements, such as addressing leg-clipping issues, marking interactable objects, and adjusting the transparency of the wheel menu. The update is available for free on Steam.
