Stetmann deployed these constructs during the End War. These banelings are equipped with an egonergy shield to protect them long enough to impact their targets, as well as the ability to launch themselves at targets and use its egonergy reserves as damage.
The mecha baneling is a suicide attacker for Stetmann in Co-op Missions. These banelings can take damage to their energy reserves before their life total. They can be upgraded to launch themselves at enemies similar to the Hunter baneling, and use the remainder of their shield amount as damage.
