UNFORTUNATELY drag the game down a few things: The story is .... almost non-existent and totally boring, your character has no character. The fights are completely unpretentious, I have played at the highest difficulty and was not required. And then the end .... the last level and the end are among the worst in history. I sat in front of the TV and thought only "Yikes ... like, over?". No boss, no great final battle, I have the BFG (strongest weapon in the game, you get the last level) not once fired because I wanted to save it for the end ... and then the game was over. There was no resolution of the story, only a meaningless nothing-video sequence.
Conclusion: As Shooterfan you can play it because the mechanics fit and it works well. But you also will not miss anything if you do not.
