Huge problem!!

Dear Modern combat team,

Ok so I know this game is older and that MC5 is out and its all right but I really like this one. I payed for the game and I want my moneys worth. There is a really big problem with the game constantly crashing. Im on a iPhone 6. This is my last request. Please keep the game playable. This game is far better than MC5 in my opinion even though MC5 has some amazing aspects and qualities. Please fix and help a fellow modern combat friends out. Thank you for your time
