The RY–589 Ultimo bot is a unique sentry bot found in the X-7a "Left Field" artillery launch in 2281.


Originally the main security force at the artillery launch, this sentry was never shut down and still patrols the artillery battery for intruders. It has a great amount of hit points and a reasonable DT; coupled with its minigun and missile launcher, it is a worthy opponent.
