 Pitted against another team of players ( riding on a separate vehicle ) , the recruits board their training vehicles equipped with laser guns , called S4 Alienators ( " Jumbo Judy " ) and proceed into the training room , blasting at cardboard cutouts and crudely drawn images of aliens amid flashing red lights . Soon , however , MIB Director Zed ( played by Rip Torn ) informs the trainees that an alien prison ship has crash landed in the middle of New York City . The guns are then " set to full power " as the trainees are instantly launched into the heart of New York , attempting to score as many points as they can by shooting the aliens in their vulnerable areas ( the eyes and shoulders ) . Aliens vary from large , plain @-@ in @-@ sight creatures to small ones hiding in windows and bushes . Certain aliens will fire back causing the cart to spin out of control .
