This is not an issue regarding IOS 11. It is the way the hack works. Before opening the game you must turn your phone to the landscape position, then open the game. If you open your phone in the horizontal position then it will open half screen and you will need to restart the game in the landscape position.
Then please feel free not to play it. This game is in BETA still and we are still waiting for future updates to be released. For those like me who enjoy zombie and base building themes, the game is not boring
These hacks and these mods are FREE and the uploaders put a lot of time and effort into hacking these games for US. If this site wasn't here then good luck trying to find a hack or even the amount of hacks that this site offers all in one place FOR FREE. You do not pay for these hacks, you just download them so if a little pop up shows up on the game to the website when you start a game then you should be HAPPY to support these uploaders and their mods. If you are not happy with the mods or the pop up at the start of the app then feel free to find another site that offers hacks. Me I am happy with a pop up because I am saving money on in app purchases, I am saving hours in game and I always play games in landscape mode! i hear youtube has some awesome hack videos, you can try there
Have respect for the uploader and dont be rude, there is no reason to use those words here
