Already having been a fan of Bill Leeb's various projects,[12] Carbon Games founder James Green had approached the band for WarMech and its predecessor album AirMech because "I wanted to work with Bill/FLA for our games [for] the same reason I love the music as a fan. It's more of a signature Bill Leeb thing in fact, as you can hear it across all his music projects - the complex layering and build up of songs. [...] Having something with the depth and texture you find in FLA songs is exactly what I wanted."[12]
During the production period of some fifteen months Carbon Games gave the band complete artistic freedom, a process both parties described as easy-going. Carbon Games as well as Front Line Assembly considered the album a big improvement over the already well-received AirMech.[12][13]
While Leeb saw AirMech as a learning experience, he emphasized the importance of the extensive dubstep programming "with different types of dubstepping" for WarMech: "In some of the songs they are the real key elements. It's more intense in that way, we just pushed it to another level."[13]
Release
The songs "Mechvirus" and "Molotov" were released for early streaming through the group's Bandcamp account.[14][15]
The original intention of Carbon Games was to issue a physical release of the album themselves. Talks with label Artoffact about the vinyl edition lead to Artoffact assuming responsibilities also for the CD issue.[12]
