Great list here :P Here are a couple of possible extensions that I haven't seen in other suggestions thus far: How about zombie animals? Also companion pets? Dogs, Cats etc. could follow you around and get turned if taken by a zombie. The dog whilst being able to protect you from attacks could be a good source of food as an emergency. Cats could hunt down small animals like birds and rabbits for food? Spawns should be in houses I think, there are houses with loot in which could be your spawn - and if you are lucky you spawn with amazing loot or you get less than favourable loot and the possibility to spawn in a town or a solemn house in the middle of nowhere. Adding melee weapons would be nice and an added mechanic could be: Spawning with no gun - start with a melee weapon such as a knife because lets face it the majority of people aren't gonna have guns in their house
