The Blueprint Brain Tank is a military tank, powered by a brain, that emerges from a set of blueprints.
Raz fights the Brain Tank in the Brain Tumbler Experiment. It's powered by Dogen's brain and seems to be very powerful, more so than Dogen. Its weakness is that it can be rolled onto its side during the fight, freeing the player to either beat or shoot its "Soft gelatinous under belly." After enough of a beating, it explodes and the player must then fight the brain powering it.
