I have played this game on AG long time ago, reached at levels 20++ only. It was fun, it was getting harder to play too. But what I disliked sofar from this game at that time were some bugs that the zombies were occasionally stuck on wall during zombie rush so they could be easily killed by ranged weapon and probably the scarcity of finding some certain zombies during scavenging, that's why it took personally for me like a week or something to accomplish a task due to also the return time. And I'd like to say that this game could be more better, realistic even if the developers could implement into it some bows, arrows etc and a campfire on compound to hang out. I have to suggest on this occasion that they should put a hotkey (Simply press "A" and then left click on everywhere randomly, preferably around the selected survivor, to attack nearby quickly. I'm used to this since I have been playing RTS and MOBA games for years.
