Love this game, it's a challenge , but I just gave them a 1 star,, because when I play with my team on missions, even though Im working on my mission,, it will say I didn't do any missions,, which is not true,, I did my challenge,, but if I have to wait until it's time for my lives to get full ,it always say I didn't do any missions which unit true,,if It wasn't for my time and efforts I WOULD UNINSTALL THIS FIR THIS REASON
