Just a few suggestions.
Ghosting in - I think you shouldn't be able to ghost in on spawn,Could get you killed without been able to react.
Graphics glitch - with blue carpet in house when you have a gun and move around it leaves this wierd effect on the carpet,cant really explain but if you take a look you will know what i mean.
Food - Food doesn't appear to restore hunger bar,Only drink.
Health - depleats too fast (imo) when your starving.
Loot Spawns - More variety in loot spawns..spawns seem okay,But i know EXACTLY where to go to get what i need,For example i need a gun run into one of the houses you will almost guaranteed to get a M4-A1 or AK either on the Sofa or on the table,Same goes for a Vest and Food been in the supermarkets.
I think the loot should be more varied to be honest because in an apocalypse situation like this there really wouldn't be much food left at all in the supermarkets as they would have been looted instantly,
Random Houses / Log cabins in the woods - To make walking from one town to anotehr not so boring.
"Loot Stash Box" spawns - Maybe these could be a rare spawn,Maybe even a % of finding one of these in the random houses / log cabins i mention in the woods,They could contain a stash like.
2x boxes of ammo for said rifle
Can of food
AI / Robots - Just courius why do these guys run around like idiots at 100mph for no reason.
Wouldn't it be better for them to walk normally even when they are after you but walk like they have a strong posture,With a lot of energy behind their stride.
Advertising - I think the game needs ALOT more advertising,Just doesn't seem to be anyone playing,I know its early days but where is everyone.
