Seriously? Infinity Ward. You have left realism. Now this is about the online crap. Not the bad-ass campaign.
So let me start off with Perks:
Sounds okay, but the ability to level them up? Whoa. Slow down. Yes, this is right. Now you can upgrade perks. And not like they are bad enough.
Defaults Perk Affects:
-Unlimited Sprint
-2 Weapon Attachments
-UAV Jammer
-Stronger Projectiles
Now, lets upgrade those:
-Faster Weapon Aiming
-???
-???
-Stronger Helicopter/Plane Damage.
Now, sounds cool, but when you upgrade perks, they default affects stay aswell.
Pretty cheap.
Now lets quickly move onto Killstreak things:
(The ones I remember.)
3-UAV (Everyone loves this)
4-Missle thingy (ADFDSAFSDFASD! From a 4 killstreak?)
4-Ammo Drop thing. (Seriously?)
5-Airstrike
7-Helicopter
13-AC130 Gunship
25-Nuke thingy that kills everyone.
Now, how easy is it to get a 3 KS? Simple
A 4 KS? Simple
5? Simple?
7? Average
13? Challenge
25. Hard, but a nuke? Please let this be a joke.
Now you go blabbing on and on and on. I spent 2 hours of my life reading about this. I left out the Campaign because it's badass.
But seriously.
Infinity ward can go find the square hole.
