My suggestion is for multiple kind of infected. I will list their specificity in here, feel free to add your ideas. 1. Sleepers: Regular Infected could sometimes be found in a sleeping state in which they would be standing in a dormant mode, until you make too much noise, or touch them. This would encourage players to sneak and be cautious. (Inspired by http://www.reddit.com/r/dayz/comments/2ak9ke/suggestion_resting_zombies_that_can_be_awakened/ ) 2. Clickers (From The Last of Us): Blind infected, they only react to sound, are extremely aggressive and stay in large groups. Again this promote stealth over brute force, and opens the way to different game play. In example, you could have someone shoot a gun at the other end of town to make them all rush there, leaving the town square empty. 3. Leakers: Infected that with lumps on them that discharges a quantity of infected pus when you touch or harm them. Making guns and bow the only viable option since you are attacking from a distance. When hit by the pus, players would become sick and could die some time later. 4. Slenders (not slender mens) : Right now, woods are *almost* zombie free. These infected would be active during the night only, in densely wooded areas. They are fast, silent, and like to sneak on you by hiding behind trees. They hate light though, so a campfire might keep them away, and a roadflare would repel them, until it burns out. They would add a real, important horror effect to the game. Bonus: There could be some rare zombies, with the infected version of the survivors skins. They would represents survivors that got infected and would carry usefull (but mostly damaged) loot on them. Some could have backpacks with food, handguns, etc. Thanks for reading my ideas, and as I wrote, feel free to add!
