The Super B21 is a fast, maneuverable, and stealthy bomber. The Super B21 features the Hunter Mode ability, which prevents enemies from locking onto your aircraft. Along with providing a short burst of acceleration and top speed. Hunter Mode lasts for 10 seconds before entering a brief cooldown. The Super B21 also has 4 rapid-fire bunker buster bombs, which have a special delayed second explosion upon impact. These bunker buster bombs also have insanely good building penetration use for bombing fortresses or other such buildings with troops. The damage of these bombs is quite serious but requires star upgrades to be paired with them to become truly useful for bombing. The Bunker Buster bomb also includes an occasionally deployable and powerful nuclear bomb damage effect that is capable of dealing massive AOE (Area Of Effect) damage. The Nuclear Bunker Buster bomb reload duration can be viewed near the bottom center of your screen.
