So many people complain about people always KoS, and they are right. It is kinda getting out of hands where the point that people just do it for the fun of it, or they want something that is more challenging. Then again KoS what make a zombie survival so tense but if zombie apocalypse was real you wouldn't kill everyone you see without information. The only way that people would want to group up would be if we had an infection that is almost impossible to care, but a medicine that you can slow the virus from spreading. Lets get down to the details Spread zombies out: On the DayZ SA there are not much zombies making it ATM non realistic witch with the Mod they are lots of them, and as usual they stick around in town and cities to hope for human flesh. There will have to be a time when the horde of zombies will have to leave the town/city to look for them around forest, hills, fields, and ect. This will also help to make snipers in the woods to be extra cautious. I know this has spoken before but it would be a nice feature cause zombies also need to eat on human flesh to survive. Are they really dead?: We have all those moments in a movie when your friend died then suddenly 10 minutes later they become a psycho and randomly start killing and eating human flesh. When a player dies if he wasn't shot in the head 10 minutes later he becomes a NPC zombie with all the gear on after but gear would become badly damaged if player died and resurrected into a zombie. 10 minutes would give time for the player to grab his things from another dead player and go. So next time when you need to kill your friend... shoot them in the head so they don't become one of those things. Player get killed by a zombie... you become one the next 10 minutes hope you are fast to get your gear. Some in big and good loot buildings: In Dayz we never had zombies that would already be in building this would bring more caution to the players and only that would work best if you had a little scout team to check the big buildings with the good stuff, like big apartments, big prisons, and ect. While searching the building there should be dead people lying around and only some when you get close enough would trigger the zombie that is not actually dead yet to jump after you. Few rooms would have zombies walking around the place, but wherever there are zombies walking in the room has to be good loot in that room. The Virus: Sure we had a point in the Dayz mod that you can get sick witch makes your blood easier to go down but this is the infection of a zombie that you will most likely get if your not careful. When a zombie bites you have a likely of a chance to catch the virus but you can get lucky cause if we had two different types of zombies, ones thats really fast, and ones that is really slow. Once you catch this virus you will have 15 mins before you pass out and become a zombie yourself witch this would lead to you are dead. Maybe you won't know you are infected in till you really start noticing the changes on you. Zombie Types (Fast and Slow): The fast one are just a fresh spawns, or just resurrected from a dead player and virus hasn't became to contagious but still that possibility of getting infected. The zombies that are very slow stayed alive for awhile, and are the one you would want to stay away, sure they are slow but virus very contagious a bite or two become infected. Its not about the scratches that you should worry about but when they come in for a bite is the time when the virus can strike. Now for some of you will think well if a zombie bites me when I'm having a battle with an axe then I'm screwed, well this would be a perfect time to have time action when a zombie comes only front of the player for a bite you will be able to see that while its trying to bite you just push a random key to push the zombie away from biting you and hit it with your axe while its staggered. If two zombies jumped on you at the same time then you will fall and they eat you up till you get up witch leads a great chance of the virus. Medication: This virus is impossible to care, but there is a way that you can keep slowing it down from spreading with some type of medication. The medicine would slow down the spread for an hour and 30 min but it will not stack, if you overdose you will die so every hour and 15 mins after your treatment you should be safe to take another one and a message should pop up when you can take it again. With this mechanic there will be less players in military bases do to they want to find more medication there would be a treatment of 4 per pack. Ending: These are just ideas that I just came up with. Some may agree, and some may disagree. There would have to be much more ideas and thought to be put into this but in the mean time this is all I got in my mind. This is mostly for having one of those challenging experience of what hardcore players would want in a simulation zombie survival. if zombies were more deadly then yes I believe that more people would help others to survive, and if not good luck trying to get through a city all by yourself with these ideas on. Main point is you can still be a cold hearten bandit with stealing from other player, or killing other survivors with a little group going but just don't try KoS when these ideas are on, you don't want to be a dinner bell for a horde of zombies.
