How should i organize my items better?

I would get rid of the hatchet and flint/steel. You have a lot of food, so there is not the greatest use for them

 

Get rid of:
Hatchet
Flint
Sugar (sometimes useful for combat)
Fish
Scooba Helmet
Flame bow
I would only keep two stacks of pistol ammo, but if you get all Tier IV guns, the deagle isn't really needed.
Blood bags aren't great either unless you're a hero and not solo.
The tent isn't the best either. it's rare, but not the most useful.
All your spare slots will be for extra ammo, as that will be the most useful use of inventory.

 

What's been said above, and also possibly shotgun ammunition? You really don't need three stacks for a good shotgun like Spas12. Sorry if I'm wrong.

 

Shotgun shells are as important as sniper ammo.
You'll be using them as frequently.
The spas12 is great for taking ot zombies.

 

Oh yes, I forgot about zombies. Sorry, never mind me. I'm an idiot at WarZ, sorry for trying to help.

 

It's not your fault.
I see WarZ as "gun PvP survival" rather than "zombie survival".

 

Good thing I'm not Mod for WarZ
If people took my advice, the forum-goers would suddenly have a massive drop in their skill level.

Of course that wouldn't be too bad. But when I start telling players to use the isolator or skullcrusher; that's when it collapses into chaos.

 

Other than what was mentioned above, it's really only necessary to carry around two stacks of food.

 

This is how i keep my inv

 

Actually in my personal opinion, the deagle and all that pistol ammo will be fantastic for shredding hordes of zombies. It has a no scope hip fire accuracy, so you do not have to aim, just turn around and unload. It is all on personal preference really.

 

Hatchet / Flint & Steel / Boat / Tent / Water Bottle / Scuba Helmets

 

Here's what I do. The only thing I keep in my inventory (until I reach an enderchest) is this:

Hotbar: (From slot 1 to slot 9) Sword, Beans, Barret, Spas, Bones, Paper, Pepsi, Wire Cutters, Compass.

Rest of my inventory: Sometimes an AK if I feel it might be needed, and two stacks of auto ammo per same. One stack of sniper ammo, one stack of shotgun ammo, and I don't bother with pistols :V Besides that, I have infection cure, and Mountain Dew or gapples I find, Molotovs, and Grenades.

I like to keep a very clean inventory because it increases my chances of getting the valuable loot in the case of a high risk loot scoop.

 

This is my set up. I'll post a screenshot later today.
HotBar: Diamond Sword, Barret, Spas-12, Ak-47, Open Space for anything, Canned pasta, Bones, Bandages.
Inventory: Misc. items on the left side. Top right is my ak ammo, middle right is my shotgun ammo, bottom right is my barret ammo. This setup is my creative one I sorta fell into loving. I tried many. this one works the best for me!

 

Get rid of:
Pistol
Pistol ammo
Sugar
Scuba helmet
Boat
Blood bag
Firebow
Hatchet
Flint and steel
Water bottle
Tent

 

Pretty much this:

But I would also drop the Pepsis. You could drop the water bottle and keep the Pepsis if you wanted, but you really don't need both. I prefer the water bottle because it's reusable and there is water pretty much everywhere, but it depends on which you like better.

Also, I see a lot of people saying you should get rid of the boat. If you travel around the map a lot, I would highly recommend keeping the boat, especially since you're not MVP/VIP and can't tpa.
There are rivers going through the island, a lake in the middle of the island, and water all around the island. I often keep 2 boats with me when I have room for them, it makes getting around the island a lot easier, and much faster. However if you tend to stay in the same place a lot, you may not have much use for it, so you could drop it.
