* ComplacentGamingSyndrome: Many people got through ''Bad Company 2'''s entire campaign only with the [=XM8=]/AN-94 loadout, occasionally switching one of them for an RPG or a sniper rifle.
** Multiplayer's not much better. Everyone uses the AN-94, M60, and GOL, all with Magnum ammo so they're capable of a OneHitKill at pretty much any range. The [=XM8=] + Under-barrel Shotgun is also a very powerful and easy combination to use. Blam the first person you see with the shotgun and instantly switch to the [=XM8=] to spray and pray anyone else.
* CrowningMomentOfFunny: Happens several times in Bad Company 1 (listen in on the first mission, when Haggard talks about Miss July and his cousin). Despite how serious Bad Company 2's campaign tries to be, it still has its comedic moments.
--> '''Haggard:''' ''"Shit, that tore it. Get outta my way, I gotta save me some cheerleaders!"''
** The game has a strangely-funny clanging sound that plays to indicate you've scored a headshot. Doubly funny is that, with some weapons, said headshots are not instantly fatal, meaning you can hear the sound ''repeatedly'' if enough bullets connect with the head.
** Hidden throughout the game are conversations the squad have, about the war, impending death, {{God}}, [[ArsonMurderAndJaywalking what superpowers they might have,]] the UFC, and who would win in a fight between HulkHogan and BrockLesnar.
-->'''Sweetwater:''' Religion confuses everyone. [[HollywoodAtheist Thankfully I am not held back by that superstition]].
-->'''Redford:''' [[ArmorPiercingQuestion So then what is [morally] good]], Sweet?
-->'''Haggard:''' [[ReligiousBruiser You're fucked. You're fucked!]]
** Assuming you're not a fan of the CallOfDuty franchise, the two jokes against Modern Warfare 2 (i.e. the "Special Ops douchebags with pussy-ass heartbeat monitors" and the "Snowmobiles are for sissies!" lines) are screamingly hilarious. Also, the parody of the [[NeverLiveItDown infamous]] [[ThatCameOutWrong "F.A.G.S." - Friends Against Grenade Spamming]] commercial ([[FunWithAcronyms "F.R.A.G.S." - Friends REALLY Against Grenade Spamming]]), where Sweetwater lampoons the idea of "celebrity endorsements" in general, [[spoiler: before the exasperated celebrity in question blows Sweetwater away with [[DeathFromAbove an attack helicopter]].]]
** The Bad Company 1 beta had a glitch where you could crush an allies light tank (the MEC one) by backing up into them in a main battle tank. Instead of just colliding and pushing the smaller tank, your MBT would literally ''drive up it and completely crush it- even causing the wreckage to disappear.''
* EvenBetterSequel: ''Bad Company 2'', especially the campaign.
* GameBreaker: The M60 in Bad Company 2. Even with its low rate of fire, its damage output at all ranges is still unrivaled by any other gun in the game. So overpowered that it and the 1911 got nerfed on the ''first'' major update.
** The Apache gunship, especially when the pilot zooms around in circles spitting out rockets, getting tons of kills ''without even having to aim''.
* GoodBadBugs: There was a bug which made almost all sound effects not play for a few moments in-game, especially when too many explosions or the like occurred at once near the player character. This gave an impression of the player character undergoing ShellShockSilence.
* HarsherInHindsight: DICE's constant mockery of the ''VideoGame/ModernWarfare'' series for ditching dedicated servers turned rather hypocritical after the launch of ''Bad Company 2'', when the servers DICE provided for the consoles couldn't handle the traffic load.
** DICE also mocked [=MW2=]'s lack of mod support and hyped up Battlefield's promised mod support a great deal. Turns out, DICE wont add mod support to their franchise either. It was explained in an [[http://kotaku.com/5485700/bad-company-2-devs-have-nothing-but-love-for-the-modding-community interview]] that this was due to limitations of the Frostbite engine, which was still a better explanation than [[VideoGame/ModernWarfare "We want you to play the game the way we made it"]].
* NightmareFuel: The BookEnds for ''Bad Company 2'' that show Russia's territory expanding are ''extremely'' unnerving. This probably isn't helped by the fact that their territory looks a lot like blood, seeping over the globe.
* PlayerPunch: [[spoiler: Flynn is shot down for the second (and final) time, just minutes after your squad rescues him and seconds after his GunshipRescue moment.]]
* ScrappyMechanic: Oh boy, where to begin?
** Almost all weapons (with the exception of grenades) usually wont work at point blank range if you're taking damage when you use them. Anti-tank missiles dont work ''at all'' if the player who fired them is killed before the missiles hit anything.
** Players with higher levels (from LV. 40 to 50) apparently run on JRPG rules, dealing extra damage to lower level players and taking less in return, [[LyingCreator despite EA stating they weren't going to do this.]]
** The tracer can lock on to any kind of vehicle, including the [[DeathFromAbove Apache]]. However, the Apache can fire a massive stream of rockets that will push back into hiding any recon class it doesnt kill outright. The ScrappyMechanic comes in from the fact that even if you manage to successfully tag the Apache, it can drop countermeasure flares that nullify the effect of the tracer ''before anyone can even lock on''. The only way to destroy it from the ground would be to fire at it yourself, which is about as easy as hitting a jet with a slingshot. For a while it was completely possible to win the match on your own by flying around the enemies' spawn spamming rockets.
** In the Vietnam expansion, machine guns fired from the boats can inflict more damage than similar weapons used in the vanilla game.
* TheyChangedItNowItSucks: Since the game was programmed with console audiences in mind, there's a lot of changes the Battlefield 2 PC community found annoying:
** In multiplayer, all characters now have bigger hitboxes than in the previous games, to make it easier for game-pad users to connect their shots (compared with Battlefield 2, which had smaller hitboxes). Unfortunately, this had the side effect of mouse using PC players being able to kill [[ImprobableAimingSkills at incredible distances]], sometimes ''[[BeyondTheImpossible around corners]]'', and caused the infamous [[FanNickname "sticky bullet"]] glitch.
** Gunships, which were massive [[GameBreaker Game Breakers]] in [=BF 2=], were nerfed and had their TV missiles removed, armor weakened, and can now take damage from any kind of weapon.
