Ok! I got a good idea where to go next. Samuel has to die by a nova 6 crawler while everyone else goes and dies on the elevator. Basically taking what we saw in the video and re acting what happend. But every one has who's who equipped. Or is may be that, I don't know if u noticed the quick revive elevator rings before it crushes you. May be all people need to be on it with who's who and dies so you respawn like in the video at the start like new since you have no body to revive.
