I've clocked nearly 6 days play time of MW3 so far (yeah pretty ridiculous i know) and from this I've discovered quite a few cool things which don't seem common knowledge. Thought I'd let you guys know about them:
- USAS12 has built in extreme conditioning, gives extra sprint. And yes, this stacks so if you have extreme conditioning and a USAS you have buttloads of sprint
- silencer reduces the fire rate of the FAD and MK14
- underbarrel attachments (noob tube or masterkey) increase the fire rate of the CM901. Basically acts like rapid fire. EDIT: I believe this may have been patched out now.
- the L86 (and to slightly less of an extent, other LMGs) has near zero recoil if you put a thermal sight on it. I only tried it for a joke, thinking "lol this is gonna suck so hard" but ended up going 24-8 the first game I used it.
- the Deagle, MP412 and .44 Magnum all have a special 1.1x multiplies for head and chest, meaning they are 2 shot kills, if both bullets are within this area
- the extended mags attachment for shotguns increases the pellets per shot by 50%. In other words increases the damage you do by that amount which is pretty incredible. If you put damage proficiency (+40%) and ext mags (+50%) on at the same time you over double the power of each shot.
- unlike black ops, frags and semtex have the same damage and radius, so most of the time you're better off using semtex
- don't use hardline if you are also using assassin as your first specialist killstreak reward. It's stupid and in fact just delays all your perks by one kill instead of making them easier to get. You'd be surprised at the number of people I've seen using this setup, even popular youtube players/commentators. EDIT: some people seem not to understand. see posts #10 and #28 for further explanation
- in previous COD games your movement speed was determined by the weapon you were currently holding, hence (for example) LMG users would switch to a pistol when they wanted to run around. In MW3, your move speed is determined by your primary weapon, even if you have your secondary equipped. So there's no point switching weapons.
- akimbo skorpions are better than akimbo FMG9s. This is personal opinion I know, but fact is that the skorpions have no screen recoil at all, which means aiming is much much easier, and the range before damage drop off is over double that of FMG9s.
- after 8 kills when you get your specialist bonus, in addition to getting all perks, you also get all weapon proficiencies. You even get proficiencies which aren't normally available for your class of primary. For example you get the melee proficiency even if you are using an assault rifle. The only one you don't get is damage. So if your running shotgun with specialist killstreaks, you should definitely have damage on, since you'll get range at 8 kills anyway. Not so the other way around.
- one of the best ways to kill juggernauts is meleeing or throwing knifing them (5 melees, 4 throwing knifes)
- if you see a guy using a laptop (to control a killstreak reward) flash him twice before killing him. He'll be blinded even while he's controlling his pred/whatever, so you might deprive him of maybe several kills.
- when using akimbo pistols, fire all bullets from the right hand pistol except one. Then press both fire buttons along with the swap weapon button, all at the same time. The left pistol will fire fully automatic at it's maximum fire cap. Works best with the Five-Seven as it has large mags and one of the highest fire caps. EDIT: this is more of a cool trick than a useful tip. In game you're better off using the pistols normally.
- when using a killstreak reward which requires a laptop to control it, press the "switch weapon" button just as the laptop fully opens. When you finish controlling the killstreak and return to 1st person view, your gun will already by ready to fire, instead of you having to wait to put the laptop away first. This can come in pretty handy.
- booby trapped care packages can't kill you if you have a ballistic vest on.
- trophy system protects you from predators.
Well, that's pretty much it, hope I've helped you guys out. If anyone has any tips or easter eggs to add, I'll edit them into this post.
