Some things that can help:

• Bottled water and dry foods
• First aid kit
• BBQ or camping stove with their fuel
• extra fuel for your vehicle
• Backup batteries for phones and computers
• A radio, something hand charged or solar
• Playing cards, books, board games and puzzles

I just looked up what these look like on the inside and am quite disappointed

Prototype 2 (2012)

It’s been a while, I can’t really remember the game well but I do remember enjoying the prototype games.

I can’t recall too many other games that haven’t already been mentioned here either
