I just wanted to tell some things that I found.
1.How to get Milie`s card easier:
First,get her on a date.Then just kill her.Some man will call you and tell you that you have to go to her house to get card.So,you don`t need to date her.
2.On the mission for airstrip when you have to plant explosive in plane on the begining you have to get on bike and drive in plane.But,you can get minigun and destroy the plane and it will stop.Still,you can get in plane with bike and continue the mission normaly.
3.Get in amunation and plant the explosive on men who is selling weapon.Than activate it and the man will start to shot you But,for few seconds even if you don`t shot him he will die
Hope you didn`t know this!
