Reanimate

You can't reanimate the dead.

Today we will be learning to reanimate a corpse.

After the geth secure a location, they round up and impale dead and living bodies on mechanical spikes. The spikes rapidly transform these victims into withered husks, extracting water and trace minerals and replacing them with cybernetics. The cybernetics re-animate the lifeless flesh and tissue, transforming the bodies into mindless killing machines.
