- 75Reviewed by NoelGood game but shortI love the story line and missions, but the campaign side is over too fast. I completed it in a day.The Pros
- Great graphics and different game modes.
The Cons- Too short. Not worth the same as other priced games (that take longer).
- 100Reviewed by DanielAmazing stunning graphics shame about the multiplayerSo when the news of MW2 got announced I was excited because we see the return of task force 141, not going to spoil the campaign but it was amazing but the other side which is multiplayer it's just the same level up business as 2019 modern warfare, cold war and vanguard it gets boring when you know you can't prestige again when the level resest and that frustrates me because it doesn't show how well you ranked and that's my only issue with the game but this cod title is amazing again and that's why recommended it(sorry if my review doesn't make sense or struggle to understand I suffer really bad with dyslexia)The Pros
- Campain, graphics, multiplayer
The Cons- Level up system
- 100Reviewed by Arron chattaway#0198649795 Call of duty MW2 CROSS GENI brought this game and was very happy how fast I got the code and how easy it was to redeem the code on my Xbox best service I will always use cd keys as the first place to get my games and everything for my XboxThe Pros

- 100Reviewed by EthanWorked wellIf anyone is sceptical if this website can be trusted well it can and the code worked great
- 100Reviewed by VernonWorkedSaved me about £30 not badThe Pros
- Fast
- 50Reviewed by LeeCampaign incredible, multiplayer very sweatyI think this is just how the new COD's are, but the multiplayers are ridiculously competitive. It's as if everyone is playing in the COD league. Although I'm a very experienced player, I still find myself struggling, being in full time work and a full time student I don't have the time to commit to the game as everyone else. The new attachment system is a joke for casual players. I have roughly 25 hours in multiplayer as of 11th December and I haven't even found a good loadout kit for warzone because I've only levelled up 10 guns to max. I can't even have fun in multiplayer because as a casual player I'm forced to use weak weapons to level up in the little time that I have to play. If you have a lot of time to dedicate go for it, if not, it's a waste of money just for the campaign, which is excellent by the way.The Pros
- Campaign is unique and very fun
The Cons- Time to kill is very fast in multiplayer
- New attachment system is a joke
- A lot of bugs and crashes

- 100Reviewed by RobIt worked for me, but there was a scareThis was amazing and it worked, but the code didn’t work at first when redeeming it through Xbox console/store itself, just in case you run into this problem, try to redeem from Xbox site through web browser before contacting cdkeys for help.
