The Battlelord is an antagonist appearing in Duke Nukem 3D and it's long awaited sequel, Duke Nukem Forever.
Duke Nukem 3D
The Battlelord is the first boss of DN3D, encountered in L.A Meltdown at the Abyss Level. The Battlelord wields a chaingun (prosthetic minigun design) with a built-in mortar launcher. Its chaingun is also significantly more powerful than the Enforcer's. The hulking Battlelord commands the first wave of the alien invasion force on Earth. Its deafening roar splits the air as its deafening chaingun and mortar rounds tear resistance asunder. It has no known weaknesses; only relentless firepower and staying on the move will win the day.
