Installed through Mistplay for units. I'm a veteran gamer.This one needs CONSTANT patches/updates. Update-I got the giant update dl/installed. The game now takes more than 5gb of space. Had to force stop most of the apps on my phone to make it happen. What a resource hog. Don't bother, won't keep it long. I'm very savvy. This is way too much for a mobile game. Only keeping it till I get to checkpoint 15 on Mistplay, then delete,great unit count, at checkpoint 10.
