It is a standard FPS. It is a decent game.I personaly liked it.
Try it out for yourself.I personally don't listen to reviewers since in my opinion they are very biased.
It has a good story and a good single player campaign.
Give it a chance you might like it.
You never trust reviewers as someone said they are bias. Look at games that did get good reviews but at the end of the day these games were terrible. Look ETW it got very good reviews however it was a terrible game with lots of bugs. Only one independent reviewer gave it a bad rating and he copped a lot of crap from the developer for telling the truth.
