In a zombie apoc, what would you do first?

There are multiple steps and priorities;

1. Get your gear
2. Scavenge a whole lot of ammo
3. Study the map
4. Choose your advantage locations
5. Plan ahead before moving to an area on the map
6. Always have a retreat plan and location if in case you are attacked by a crowd of Zombies.
7. In multiplayer scenario, plan and pick a leader. Cover all the directions.
8. Most important of all, don't scatter or row away from the team. Stick together and you'll service even a herd of Zombies.
