Just played this through recently despite owning it since launch. Really bad game, not even comparable in the slightest to the proper MW2 from 2009 which is easily one of the greatest games of all time. Atrocious campaign. Not even possible to complete on Veteran difficulty on the ghillie suit chapter unless you tried 300 times and get a lucky run. No skill involved, no stealth, dozens of enemies in armour, no checkpoints, just get destroyed in 1 hit no matter where you stand with absolute pinpoint accuracy. Think of the hardest game you’ve ever played and it’s got nothing on this game’s veteran mode. The gunplay & movement is slow & terrible too which means multiplayer is rubbish. (edited)
