1. Now this one I believe may already be in the game and it is a destructive environment. now i dont mean to say just the ability to shoot down a couple of Cm's off a traffic blocker or to shoot down a small tree i mean full blown destructive environments like: destroy walls cover, vehicles, and perhaps even the ground whether from a city street or a buildings floor.
2. Dual Wielding. (just for giggles)
3. Online i believe that you should have more health. Now I am not saying you should have to empty an entire mag into a guy but maybe a little more than 3-5 shots to kill a guy maybe it might take 6-8 with some guns or some thing i personally believe it could make the game a little more unique and a little different. I also believe it would make the game that much more competitive because it seems to me that a lot of competitive games like: Halo, Gears of War, and Killzone give the player more health so that they might go on to do a great many things and what not.
4. Finally parkour. Parkour in a nano super suit would probably be the coolest thing that i have ever seen in my entire life especially with the first person view. and it could even maybe change up the gameplay that much more.
5. Prone would be neat.
6. Two separate streaks one for the kills that you get and these would give you items beneficial to your team like UAV and Couter UAV or maybe even ammo drops or something. And "tag streaks" if you will that would give you more personal killstreaks like gun ships or orbital strikes. I say this because at many times I don't get tags just because I am sniping or they are just to far away for me to care.
I would like to re inform you that these are simply suggestions not forced statements, just things that I think would spice up the gameplay and be something new feed back would be great and please keep the harshness to a minimum this is for the sake of being heard. Thank you for reading this essay. (If you did)
