Founded as the Chrome Lacrosse Club, they began play as one of the league's six inaugural teams in the 2019 season alongside Archers, Atlas, Chaos, Redwoods, and Whipsnakes.

Unfortunately, in the title game versus Chesapeake, the Outlaws were unable to muster that same kind of comeback magic and fell to the Bayhawks 16–6, falling one win short of their first MLL Championship.

On August 23, the Outlaws defeated the top-seeded Rochester Rattlers 12–11 to win their first MLL Championship in the team's 9-year history, thanks to a go-ahead Drew Snider goal with 56 seconds remaining.

After trading John Grant Jr. to the Ohio Machine, they won their last six games of the regular season to be one of the seven teams in the league to finish 8–6.

Denver would use a 7–0 run in the second and third quarters, and a nine-point performance from Matt Kavanagh to defeat Dallas, 16-12 for their third championship in five years.

In a five-game regular season, the Outlaws stormed to a 4–0 start highlighted by an 18-6 throttling of the new Connecticut Hammerheads and a 13–12 overtime victory over the defending champion Bayhawks.

Following the assignment of home markets for the 2024 season on November 14th, 2023 , they were rebranded with the identity of the former Denver Outlaws of Major League Lacrosse.
