Okay, so I've been playing MW3 multiplayer... for..... uhm.... 6, 7 hours straight.
And I'm loving every minute of it!The graphics are slightly better than MW2, but where MW3 REALLY shines is in the new weapons, the strike packages, and the balance of all of the weapons against each other. (At least so far)
Weapons: Shotguns are a primary class again. WOOOOOOOT. The Spas-12 is still awesome as a shotgun with a medium sized range when ADS, however it's not completely OP as if you miss, or they are farther away than a few feet it will most likely take 2 shots to kill someone, 3 if they are somewhere between mid and far away.
The assault weapons are pretty good, though to be honest I've mostly been playing with my shotties. (Those of you who played when we played CoD4 a lot know my favorite class
)
Strike Packages: This is a great addition to the game imo. You have Assault, Support and Specialist.
Assault is what everyone's used to, blah blah blah. Most of the kill streaks are pretty great at getting kills, but they reset when you die.
Specialist is pretty neat too, lets you unlock more perks as you get kills, different perks unlock at different killstreaks, even if they are in the same category. (You can choose 3)
Support is one of the coolest ones I've seen. It's amazing for a rusher like me, as it doesn't reset upon death, and theres a few kill streaks that can net you some kills if used right.
One of the funnest was the Boobytrapped Care Package, I've gotten up to 4 kills with one, with some clever manipulaton. (Pretending to grab it but getting killed while getting it, which is great cause the streak doesn't reset upon dead) Can also use a stealth bomber, and can also use a Osprey supported care package kill streak.
Also, so far I've yet to find an over powered gun. The shotguns are pretty good, but on an open map you'll get ahnniliated if they catch you in the open, and on close maps the range is short enough that it's usually a 2 shot kill for most of them. The snipers can quickscope still, though the power is down low enough that you have to get a solid body shot to 1 shot someone. The assault and SMGs are nice, UMP is still pretty good. They have nice power and clip size.
Really, I'm enjoying the multiplayer to pieces. It's definitely the second best multiplayer CoD game, if not better than CoD4, but I'm holding my breath to see what they higher level weapons are like.
Imo you should buy it if you like fast paced action multiplayer with balanced guns and kill streaks. But hey, that's just my opinion
