I'm hoping for more variety in zombies at least, and the default ones not being Olympic sprinters. Also, there should be more zombies around in general, especially out in the wilds. While more far off, any melee system would be welcome. Although difficult to implement in an engine that does not by default support melee, it can be done as evidenced by other Arma 2 mods. This should lead to players not starting with a gun but rather with a CQC weapon, making guns rarer and more powerful objects. Zombies should be less vulnerable to gunshot wounds.They should be only killable by headshots, thus making slower zombies more viable. They should also be able to be crippled. That is, shooting out a zeds legs should make it crawl towards you, or shooting out only one leg should make it hobble slowly. This would make the players play more carefully, as crawling zombies in grass may be difficult to see, and unloading a clip into a zombies body will not necessarily bring it down. But these are just a few of my personal hopes. I'm sure most people wouldn't agree with them and love the Olympic-qualifying zombie sprinters.
