We shall see. I haven't thought of too many mods to make just yet.
Mods that I'm mulling over...
Make the cars you see in maps drivable, carry passengers
A rappelling perk, so you could rappel down buildings and climb up buildings
Throwing knives
A helicopter that could hold passengers, maybe be flyable
what about instead of having grenades or claymores you can pick "sticky Camera" and you can stick one to a wall and have a little screen show you wnat it sees or even the "snake" that they use to see around corners and through doors
