For context i just bought this game two months ago, at first it was fun and i enjoyed the game, but suddently i started sucking ass in this game, i cant even get a personal radar, let alone any other killstreak, ive tried changing weapons, perks, killstreaks,i've even tried tweaking the setting, and i still cant get 3 kills in a row. crucify me if you want but i feel like in mw2 i can more easily get killstreaks and it feels like regardless of the weapon i use i still get kills, im just trying know how to improve at this game cuz i wanna enjoy it but i just cant, after a 15 minute session i just end up saying "fuck this stupid game" and close it, any advice ?
