I always see huge boats arriving to the port of my city, huge, black and red, full of GASOLINE boats.
And I let my imagination do the work. I imaging one of those huge boats with a gasoline contaner and a kinf of freezer for food, and that opens a sort of door leting out a small ferry with armored vehicles like a hummer or a sport car with high suspension. The ferry would land on a port or beach letting a super trained team of shooters to look for gas, food, water,cars( for replacing the bad parts of the cars) and ammo.

Step 3: Gather Supplies
---Food and water, obviously. Also pots, matches, weapons, medicines, fuel, survival manuals, and anything else that could prove useful. (continue this step until end.)

Step 4: Split up Group (Possible)
