I'm pretty new to this game, been playing for about a month now. I got to level 120 and was finally able to make the gyrocopter. I've been looking forward to this for a while. So after figuring out how to fly the thing, which there are zero in-game instructions or keybindings that I could find, I flew around to try it out. I saw a shotgun factory with a helipad so I thought I'd check it out. The helipad was clear, no zombies so I did my best to land. It doesn't fly like a helicopter at all that I can tell. There's no vertical up or down movement, it's all based on inertia like a plane so I had to kind of slide slowly in. As soon as I touched down, 10 green zombies appeared sleeping around the ring of the helipad. I hadn't woken them yet so I thought I could get out but you have to runway to take off. As I'm grinding into the side of the helipad all the zombies woke, swarmed me and killed me in two seconds. So now my new gyrocompter is on top of the Shotgun Messiah factory, all my tools, weapons, and most of my mats are on top of that thing and I have no way to go retrieve it. Those green zombies need to go... They seriously need to be nerfed. It's just not fun
