I mean 'strategy.wise'. Any particular order etc.? I ask, partly because chasing about opening all those millions of boxes ..I find a pan in the *** guys!
Well Strategy wise, I stick to stealth and sometimes go all Gung-ho. One Really COOL Strategy to UNLOCK Bell Towers FAST, I fly into them right next to the Radio and unlocked all Bell towers within 15 mins in South and then when North opened out! So efficient strategy!
