How do I see how badly my pilot is damaged because I can't tell how bad it is?
For pilots I'm not 100% sure, but the Mech has a health bar in the images at the bottom. Also has a blue>grey body part indicator and you can select a Mech and press "i" or open the info tab to get a better look at the damage
I noticed the old MCG pilots are in this because I see the files, but do they unlock in the Carver V campaign or is it only other ones?
Not in the Carver V campaign I believe, but they are in other missions..
Is there a way to fix the pilot videos because since I bought this game when it came out and throughout all installations, the pilot videos show up but it is just a still image and not a video. What is up with that?
Not a clue, I think the videos are broken, can't say I ever noticed
Is there a list of all the major changes of game play from vanilla and not just the differences from the previous patches?
There is a plain text file in the main install folder called "version.txt" .... this shows all the major changes to the stock MC2 from MCO ver 0.030 (28012011) to the current version. This file in its entirety is all the changes made, there is no "bullet-point shortlist"....
Hope those answers were helpful ....
