"The acting and writing of the series would be great enough on their own, but there is also an impressively animated production holding it all together. gen:LOCK has a striking look that wears its anime influences on its sleeve, yet feels like an entirely unique project. The fight scenes are fluid, and the first full scene with the Holons will have you aching for more. But they're always filled with personality as each action scene is imbued with an extra sense of humor or drama to take it up a notch."

gen:LOCK is now available for streaming on Rooster Teeth, and the synopsis for the series reads as such, "In gen:LOCK, Earth's last free society is on the losing side of a global war, and recruits a diverse team of young pilots to control the next generation of mecha—giant, weaponized robot bodies. These daring recruits will find, however, that their newfound abilities come at no small cost. As Chase leaves behind his life as a fighter pilot to become the first candidate for the program, he finds his endurance, as well as his very identity, will be tested beyond anything he ever imagined."
