Help me find the game!

Greetings to all the local forumers! I'm hoping for your help in finding the name of the game! I would have been able to find it myself, but unfortunately when I played it, I was just a kid, and I had trouble getting through it. I had already contacted chatGPT, but he did not give any good advice. I remember that the game was a shooter (most likely a linear) from the first person, as the protagonist goes into the lab (Most likely there was a zombie virus), and after the end of the mission in the lab and the GG goes into the elevator with 2 partners, partners chops off the head with a green laser. And something had to be done to keep the GG from getting his head cut off as well. This is one of the prologue scenes. Further I do not know how the plot develops, because all the time dying in the elevator. The year of release is probably 2008 to 2012. I was playing on the pc at the time. Other platforms do not know. I also remember that the game had a good graphic.
There is a list of games that offered chatgpt, but these are not the games: (Maybe Fir 3 comes to me, but in my memory style was different)
Thank you in advance for your help, and I already thank you that you decided to spend on me his dear time!
