Thanks for aswering.
I'll clarify the first one: When one dies, there will be a counter counting down to the moment you can respawn. Sometimes I will respawn as soon as the counter hits 0. Sometimes I just get the screen with options (respawn/spawn on buddy) and sometimes that screen stays there for a while and then i respawn automatically.
Anybody know if there is a system behind that?
About the last question, for example if I start in dessert village, I almost always run to a position where I can see the stairs on the side of the level going to the well. Free kills with the sniper. How about you guys?
