Watch out, this is not an ordinary ball. It's the Coronian Roadrunner - a spherical drone set to crush, kill and destroy everything in its path. Its unorthodox design makes it capable of travelling at high speeds, and additionally benefit from the Spinblades scattered on the battlefield. When a Roadrunner chases its target down, it will cause an explosion with tremendous power, heavily damaging every soldier and tank nearby. The explosion will briefly disable the Roadrunner's systems in order to recharge the weapon, making the unit immobile and completely defenseless for a few seconds.
Effective against groups of vehicles and infantry.
Very fast, even faster when boosted with Spinblades.
Can quickly crush infantry.
Several Roadrunners can easily destroy unsuspecting hostile units caught within their blast radius.
Can detect disguised enemies.
Immune to poison, radiation, hijacking and mind control.
Roadrunner is not destroyed in the explosion.
Can only attack close range.
Cannot affect aircraft and structures.
Unit is temporarily disabled after attacking, thus very vulnerable to hostile counter attacks.
As of 3.3.4, there's a missing '%' in the Roadrunner's scalar definition, making it deal 9500% damage against Basic/Animal armor types. This doesn't affect gameplay however since Roadrunner one-shots Dogs/Spooks and Engineers anyway.
