	Various Trophies...

Find a weapon box or container and remain idle at least four real time hours next to it. Open the container to claim a Legendary weapon.

In an early chapter, you'll meet a girl who asks you to scrounge along the beach for water and food. She'll next ask for canned food. Once you retrieve around 10 or 20 cans, toss it on the ground and then kill yourself. As the recover process follows, quickly load your last checkpoint and access your inventory. Scroll down and you should find that the cans are back in your inventory. They also should be on the ground where you left them before loading your checkpoint save. You can keep repeating the process to mass a huge pile of cans that you can use to gain experience and money.

When you are playing as John Morgan, enter rage mode. John will pull out a staff, which is separate from his standard inventory. If your inventory is full at that point and another weapon pickup is nearby, you can quickly select that other weapon to replace the baton that John is carrying. That will add an additional weapon to your inventory, so that you are now carrying more than the usual maximum of 18 weapons. You can continue to expand your inventory in this manner, by activating rage mode and swapping out the baton for addition items as your inventory swells.

There are twin zombies at the Pinai Ferry Station that must be killed. The first twin can be found at the beach to the north of the ferry station. It will appear from the lifeguard's shack on the beach. After killing it, go to the billboard with the pick-up truck on top of it at south section of the ferry station. Go to the back of the billboard and climb up the ladder. You can collect sniper rifle and bait from the truck. While up there, look toward the ocean and notice that the building to the left is open. Throw the bait near the doors to draw out the other twin.
