Pros:

Single Player Friendly
Search for weapons/items
Weapons room is safe

Cons:

Door in house next to start has a door that can't open all the way, which means one of the metal parts can't be obtained, therefor you can't beat the game.

Conclusion:

Overall a fun gameplay, but it's impossible to beat because of the door in the house, get rid of the zombie bodies that start in that house and it should fix it!
