Has anyone tried using Riot Shields? They're hilariously fun, and you get good points, but unfortunately your K/D suffers.

I liked the campaing, it had interesting cut scenes and good maps but Ill have to say that the multiplayer is a bit broken.
Im sorry to say that lightweight pro, marathon pro and commando pro class with tactical knive is really noobish class and it makes the game feel broken sometimes.
It just isnt fun because you can just slide like 5m really fast and hit like 3 guys with tactical knive before somebody has the time to shoot you.
Another noob class is akimbo shotgun classes primary weapon sniper so you can run faster and get the camosuit, secondary weapon those models or rangers with akimbo.
perks: lightweight pro, marathon pro and commando pro.
And the multiplayer is mostly running around and dying and getting k/d=0 or camping where its like k/d=20+
Well its just logical to camp if you dont want to die -_-
But the multiplayer is fun if you get to server where other players are trying to complete the objective and not to camp and kill only :-(
ofcourse tdm is about killing.
Oh and not to forget the thermalscope, its just sad when you get killed by person who uses it and spots you from locations where you normally wouldnt be seen. That happens normally in the wasteland map.
There are good and bad things in the multiplayer, but its still fun and addicting game.

This game is terrible. Save your money and just play MW2.
