Thinking about purchasing have some questions

[Brashin]

Hi Everyone, I searched through the forums and couldn't find the answers I was looking for (which is possible that I am using the wrong words to search)

I was wondering if I could get some answers to my questions:

1) Can you save a game in the middle of a mission. I usually do not have a couple of hours to play a whole game through and may only have 30 min here and there and would like to know if I can load into a saved game in the middle of a mission.

2) Do units gain experience for kills? Do they get more accurate, reload faster, anything along those lines?

3) Do units carry over from mission to mission? I hope so as I'd hate to think I always have to start with new guys going into every battle.

4) Are the missions linear, or is it possible to fail a mission and have consequences...other than losing the game.

Appreciate any answers to the above, Thanks
