Bought the game and didnt even question if I would see adds or not. However as I was playing the game (not during transition of stages), and ad for KOF came out and as soon as I closed it and resumed playing, another ad came out... I really like the game and thats why I bought all three metal slugs but this is not acceptable. It might be if it was a free app but really? I dont like to give one star ratings but this time I really had to.
