I honestly think it ' s intentional . Vortex shield , well , creates a vortex . A vortex that seems to absorb all incoming fire . A lot of this is going to be bullets , titan shots , etc . If you look at the vortex shield while carrying the enemies bullets , they all seem to spin around like in a vortex obviously , as if the vortex shield has magnetic properties . Considering the vortex shield ' s magnetic properties , perhaps it ' s not too big of a stretch that the vortex shield is strong enough to pull out a fire star which is pretty much a metal shuriken ! out of a titan ' s chassis . And perhaps that also means it ' s an intentional mechanic . That ' s what I think , at least . <| sep |> Supposedly he had a manic episode and was admitted to a mental hospital .
