Best parts are the Aim-Down-Sights and Mech teaser for me.
Also happy for the Pistol buff, i always love me a viable Pistol.
For the customization, i hope we something get cool scifi armors or something, instead of immersion breaking stock hats.
Now if this gets vehicles and loadouts. Id be very happy already.
Also if you want to "revolutionise" the game, hear me out ... "Snap-on-cover Mutator" , how about that huh... oh and in conjunction with an adjustable third-person-camera because i cant shoot squat with my head in the crosshairs.
And in terms of priority id put a Campaign at the very bottom of the to-do list. With offline-multiplayer and bots you can get infinite mileage. There is a reason players still play and enjoy UT2004 despite being over 20 years old now... because the industry gives us nothing.
