I'd recommend learning about zombies first
clearly too short for a test, theres loads of more things you need to learn and heres most what you did wrong.
1. the weapon store wouldnt have any guns mostly becuse the owner or 1 or 5 of millions could have taken them. (when i said 1 or 5 i ment there might have been someone who teamed up.
2. id take the mp5 and katana becuse the mp5 has alot more magazine in it and you need to "Dissmember the head or destroy the brain" witch means you could just shoot a zombie once in the head.
3. going to the mall would be a great idea but if a guy just sits at one place he wouldnt turn that unrealisticly fast and run like in games from 1992.
Im i impressed... Nope but the rest was good. witch was.... eh.... 10% of the game.
