A/N:Yes this is a RWBY crossover with Nazi zombies and the newest map Origins but I am going to go through all the map in time line Order expect the Green run series and Mob Of The Dead those come later other than that enjoy!
It was WWI and team RWBY was sent to find doctor Richthofen in northern France along with Dempsey,Takeo and Nikolai.
"Where is he? and what are these things?" asked Ruby as she stabbed a zombie with Crescent Rose
"I don't know if we find him we'll ask him" said Dempsey
As they were running through the trenches they found an empty room and at the end of the room they found the doctor but before they could say anything zombies ran at them fast the whole group readied their weapons when all of a sudden a giant robot came and tried to crush them luckily they all dodge out of the way bad thing is they all lost their weapons and started of with a Mauser C96 and frag grenades.
"What!? Where's our weapons?" asked Blake
"They are gone, but you can get them back it's going to be hard though" said Richthofen
"Doctor what are these things?" asked Ruby
"Zombies, but not the kind you think they don't eat brains they will keep killing until we are all dead" said Richthofen
Yang was about to ask another question when they heard a voice
"Please you have to help me I just want to go home" said the mysterious voice
"Who was that?" they all asked
"Her name is Samantha she is a little girl and she needs our help" Richthofen told the group
A/N:Sorry for short chapter I ran out of ideas and don't think I didn't put detail in here I am going to show little detail at a time and/or medium detail for those of you that have played origins you already know what the scenery looks like
