Zombie Apocalypse

So im not sure what to do for this sooooo maybe give me imput how to make it better? Anyway thsi is a zombie apocalypse you live in the mountains and you snowboard the zombies freeze or go to high for them and the just die because their lungs dont know how to adapt to new places. So the rokie mountains where you live are mostly free of zombies but other survivors dont think that they think its swaming.So you need to get new stuff and some food so you and your older brother Devon that also snowboards you guys go into a town kill lots of zombies in the way and grab some new stuff and adjust stuff all of that and when you arrive and a store some people tap you on the shoulder. You can be whatever gender idc anyway that was the story and the group of people you meet are Alex,Finnley,Archer,Oscar,Robert,Chase,Miles,and then the only girl is lily or ash.Alex,finnley,and oscar are the 19 year olds, Robert,chase,and miles are 18, you and lily are 15 so your brother is 20 turning 21 next month.Have fun mooons i dont try on the voice at all. and dont mind the photo
