Set in a wintry research facility, Bio Lab contains a mix of medium-range sightlines and interior combat, with a fair amount of elevated positions around the outer edges of the level.
Map Scorestreak: None. However, you can detonate moving containers of hazardous material to kill any enemies nearby!
Bio Lab is divided into three connected exterior areas and one larger central facility. The titular Bio Lab facility in the center of the map connects to all parts of the level, so you can stick to CQC on the interior if you prefer, or you can transition to the outer areas and rooftops outside as needed.
The outer areas have longer sightlines and more elevated positions. Keep a sharp eye out for distant enemies behind cover or on rooftops when you’re moving out in the open. Hugging the walls of the Bio Lab or other adjacent buildings when moving is advisable.
