These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Broken Base: MOH 2010 and Warfighter have split the franchise in terms of whether they're worthy of the brand name, but the majority at least really don't like Warfighter, as it was the worst-received game in the franchise.
Medal of Honor: Doorfighter, after Miracle Of Sound made a song called it in reference to Warfighter's rather thorough system to how you breach a door.
Fridge Brilliance: Generally, the first level in any game is an easy one. But Frontline's version of Omaha Beach will kill you, repeatedly, if you don't take the right path, and it's not explicitly marked so it's pretty much guaranteed to require at least a few restarts. One suspects they did this (killing you a lot) on purpose to represent what storming that beach really meant.
Memetic Mutation: The Bread Is Deliciousnote In Frontline you could recover a small amount of health by eating freshly-baked bread, which would be accompanied by this message.
Your Disguise Has Been Blownnote Again from Frontline, in Operation Repunzel, the game apparently believes that, absent a reminder, shooting your way past four Germans and an alarm system will not seem like blowing your cover for the player.
Narm: The opening level of Rising Sun puts the player on board a battleship during the middle of the Pearl Harbor bombing, where they have to navigate the bombed ship by using a fire extinguisher to put out various fires in their way. Unfortunately playing on co-op reveals that instead of carrying the tank with one hand and aiming the nozzle with the other like any functioning human being, the player character instead leaves the hose attached to the tank and aims the extinguisher like a gun.
Snark Bait: Warfighter gets a lot of snark for its title, with some people saying it might as well be called Medal of Honor: Gunshooter.
For what it's worth, "warfighter" is the US Department of Defense's catch-all term for any individual personnel (armed or support) regardless of branch of service or nation of origin (so a Royal Marine seriving under the UK flag is also a warfighter). It is generally used when the other catch-all term, "service member", does not sound macho enough.
Tear Jerker: Medal of Honor (2010)'s ending. Rabbit dying slowly. In first person view. While your comrades are trying desperately to keep you alive until the helicopter arrives.
In WarfighterPreacher screaming in rage over Mother's death and also his funeral at the end
Panzerknacker Unleashed from MOH Underground. The first level had dogs that could be killed by 8 pistol shots or one shotgun blast. The 2nd level had zombies armed with automatics and ridiculous accuracy that explode when killed as well as armored knights that are always charging at you.
Uncanny Valley: Multiple reviewers have noted this regarding the pre-rendered cinematics by Digital Domain in Warfighter. Everything is incredibly photorealistic and could actually be mistaken for live-action... but the technology still can't get human faces quite right, and the result is incredibly jarring and unnerving. Preacher's wife and daughter get especially hit hard with this.
Unintentionally Sympathetic: The enemies in Warfighter seem to be seriously outclassed at every turn by the protagonists. The robot sections in particular got a lot of people annoyed that we were supposed to be rooting for the gun-armed killdroid when the enemy's only defenses against it were small arms and rocks.
The Woobie: Rabbit. Poor Rabbit. He falls from a helicopter, gets the building blown up around him, forcing Mother to drag him to safety, gets shot, jumps off a cliff, gets captured, escapes, gets captured AGAIN, is tortured, but then rescued, but finally succumbs to his wounds while waiting for a rescue helicopter. The worst part is that this all happened over a period of a few hours.
