in your lobby invite 3 other ppl. go into private match change it to der riese. back out. now heres the glitch. keep going into private match and backing out until one of your friends "leaves" the party. he is really still there. start the private match up. in the middle of loading your friend should appear in the loading screen. when you start the game message the friend that "left" the party and tell him to back out.(he wont be able to hear you) after he backs out he will rejoin automatically and will spawn in the stairs.(you HAVE to do this on round 1)
