Let's Survive

It begins with seven people.
Ives is sitting in the bar alone. It's Vic's birthday. Jack is graduating in a week. Riley is dancing with her mother. April is writing a song on her guitar. Bruno is bored while working at the construction site. Akito is rock climbing.
Then little meteors start hitting the ground and they're radiating toxic gas that makes people into zombies.

(Don't ask where they get all their gas masks and crazy weapons, I thought it was cool and don't have any logic behind it yet)
