keep in mind this isnt the full level, also keep in mind the difficulty the level is on, plus, those teammates WILL kill you if you fire on them, they wont for a single stray shot, cod is trying to mix whats cool and at the same time, make it more immersive, its immersive in the sense tht you feel your doing something wrong, other than that, logically it isnt all that 'real' nor did i say it was, i also dont get offended that easily

this video isnt the full mission also, because you get heavy resistance from swat later on, also, you may thin the reaction time for the guard at the elevator door was slow but in reality, i doubt regular guards keep guns at airports, turning around to look at elevator that i see every day but now i notice huge ass guns, i dont think my reaction could be anything significant, so it wasnt about the realism of the scene, was about the fact that the game actually made you feel bad[atleast the firsttime playing]

cod really isnt known for replayability, atleast not in my eyes and thats because they script almost all their events
