Go to Mars, first area you start out as, go cave hunting. In one of the caves you will see a hive enemy. Kill him and he screeches loud (make sure your volume isn't high). Go outside of the cave and you will find a knight on a beast with other hive enemies around him. Kill the knight and you can ride the beast. It only lasts a minute but it is fun.
Edit: for the idiots that don't believe, I uploaded the vid to youtube. You can suck my dick afterwards. Enjoy
