I hate that I have to go to the main menu to change my items for my grenades, land mines, medicine, herbs, etc. I have played other games that does this and they can change the items by holding R1 and pressing a cursor or better yet a square to scroll the items. Like for grenades, I can scroll a particular slot for all the grenades that I have available in my inventory by holding R1 and pressing square to scroll left or circle for scrolling to the right.
The throwing animation is slow. Hold grenade button to throw farther, quick press to throw grenade closer. I can't even cook the grenades. I can't even throw a flashbang while still undercover. Can't do blind fire while undercover?
I'm one of those players that like fast phase gun trigger commando-style loud etc. The duck and cover remove the andrelaine rush feel for me.
