Stuff that was AMAZING in the PC Multiplayer demo (haven't gone MP on retail yet):
1) Ability to aim down sights on-air after a Power Jump (enables headshots after a powerjump, makes for more dynamic playstyle, throws your enemy's aim off and it's just awesome!). The way it is now, you just spray bullets from the air like a goddamn idiot!
2) Ability to Sprint while reloading a weapon (enables you to sprint-get the hell out of there when the automatic reload kicks in or when you are caught off-guard while reloading). Is Alcatraz REALLY too stupid to do two simple things such as reload and sprint? I can do it in real life, for christ's sake... He's a Marine in a NanoSuit!
These two things alone made the entire game SO MUCH MORE DYNAMIC. I would LOVE to see these in the Single Player Campaign! They were in the Multiplayer demo, so what the hell gives?! The ability to play the campaign with a dynamic playstyle akin to Crysis 1's Speed Mode simply made the entire game for me. Now I feel like I was misled into buying the game by false advertising.
Is there any way to enable these two abilities through console commands or something like that?
NOTE: I have also found incredibly strange that the Marshall shotgun (AND THE MARSHALL SHOTGUN ONLY, NO OTHER WEAPON IN THE ENTIRE GAME) allows for sprinting AND sliding while reloading! (no on-air ADS after powerjump though).
NOTE 2: It would also be amazing to be able to Aim Down Sights during a Power Slide...
