Props

A list or props for our opening title sequence:

Gas mask - this to create a mystery around a character as you can't identify them and it also provokes a sense of danger as the audience won't know why he is wearing it, keeping them guessing about what the film is about.

Hazmat suit - Also makes the audience aware that danger is present as well as shrouding the character in mystery by covering his body, not allowing the people watching to see his/hers features.

Gun - Again highlighting the fact that danger is present, showing the character needs to protect him/her self. In combination with the two props above shows extreme danger.
