Addition: Make helicopter crashes much rarer and also make them the only way to find High tier weapons. Currently, it is too easy to find a helicopter crash. Just play at night and hang around Stary and they'll be extremely easy to find. Maybe only have 2 on the map at any given time and have them at oposite sides of the map seperated by at least 10,000 meters. Also, make it so that you spawn with something like a hatchet, baseball bat, cricket bat, or knife (giving hunting knifes the ability to both kill and retrieve meat). This way, everybody starts with some kind of weapon to defend themselves, but not to the point that they will go around killing other players with it since that are just as heavily armed to start with as you, or, go around killing zeds. As far as zeds are concerned, they need to do as much damage as the zombies in Left 4 Dead 2 on expert difficulty (about 10% health per hit). This makes them a much larger threat. To continue with the point made by Sutinen, zombies should not respawn for maybe 10 minutes after they are killed, but spawn in much larger numbers to start. Setting the spawn of zombies to hospitals, houses and apartments would also be interesting as that is where you might expect them to come from. So when the server is started, the zeds would have their start locations marked and would spawn when a player is within visible range of the spawn, and de-spawn when they can no-longer be seen. Major cities would maybe have 50+ zomibes at server start, and that number will fluxuate depending on hour many are respawning and being killed. The number of zeds per town would be around 10+, and minor cities such as Zelegosk and Stary would have around 20+. In other words, the larger the population, the more zombies. Edit: The melee weapons will not be at all audible to zombies. Meaning they would be a safe way to eliminate a very small quantity of zombies (2 or 3) in an area which is reasonably populated. A survivor would also have a 1 in 10 chance of spawning with an M1911 or revolver.
