Fight!

The National Havoc Robot League (NHRL) is the world's largest robot fighting league, with a social media following that reaches hundreds of millions of fans and delivers billions of views every year.

Each season, thousands of competitors from around the world descend on NHRL's US arena for explosive head-to-head tournaments where the objective is simple: destroy your opponent's robot in three minutes or less.

NHRL is redefining what a modern sport can be. Combining deep engineering, cutting-edge technology, and high-stakes entertainment. Some of the brightest and most creative minds in the world design and build these machines using CAD, precision machining, 3D printing, and advanced manufacturing.

NHRL runs a series of Open events where anyone in the world can register to fight against the very best, climb the ladder and become a Pro Robot Fighter. The top eight from each Open event qualify for the NHRL Pro Tour, with the season culminating at the NHRL Pro World Championships in December 2026.

Havoc Robotics, NHRL's parent company, has built its tournament software, infrastructure, and broadcast facility from the ground up with a master control room ingesting 100+ video and audio feeds to deliver live broadcasts in stunning 4K. Every fight, from every angle, is uploaded immediately to brettzone.com so fans and competitors can rewatch and share in seconds.

NHRL is a privately owned company, founded in 2018.

What is Robot Fighting?

Robot fighting is a competitive sport in which custom-built, remote-controlled machines battle each other inside an enclosed arena. Competitors design and construct their robots to withstand damage while using weapon systems — such as spinning blades, flippers, and hammers — to immobilize or destroy their opponents. Robots compete across a variety of weight classes, attracting participants ranging from professional engineers to students and hobbyists. It's a thrilling combination of engineering creativity, strategic thinking, and head-to-head competition.
