Certain weapons (i.e., virtually all of them save the Modern ones) are, too. For instance, Rudolf's Rescue, Tommy's Typewriter. One of the very few exceptions is the Royal Knife, which they clearly couldn't think of anything for. The National counterpart, Konrad's Knife, is a bit of a stretch, too.
Further averted with just about every weapon released post-Tier 2 weapons. They all use their real life designation (for instance, Scoped M16, Micro-Uzi, M32, etc.)
Anachronism Stew: With the addition of the Medal of Honor and Dead Space weapons and clothing, this is game has everything from WWII-ish to modern times to futuristic mixed into one. At the get-go, though, it still had pirates and ninjas.
A-Team Firing: If you don't aim down the telescopic sight of a Sniper Rifle, it seems to be capable of hitting anything on your screen. Even if that part of the screen is behind your rifle's barrel.
Blown Across the Room: Explosives and tank shells will frequently throw infantry around, but the Soldier class' Blasting Strike will throw everything that's not the environment around — in fact, it's a Soldier's only real defense against tanks.
The Amassing Force widgets from the Wizard sets are... something like this. Both fire balls of magic; one repels infantry and vehicles, the other sucks them in.
Bribing Your Way to Victory: While Battlefunds do allow you to level up faster and gain more Valor Points from playing, they are otherwise used for strictly cosmetic items. Indeed, a couple of topics appeared on the forums about whether such items ends up attracting you to shoot at them...
Not to mention, Uber/Super weapons, which are buffed versions of the regular guns available for extremely high VP costs, or slightly more expensive than the Regular guns if you use real money.
Battlefunds also allow you to purchase special combat oriented widgets, but most of them are virtually identical to certain class abilities.
Car Fu: Once they get up to a certain speed, jeeps will instantly kill any enemy player they hit dead on, making this a popular tactic on certain maps.
There's a widget that briefly increases a jeep's speed and allows it to plow through enemies, enemy jeeps, and tanks with impunity.
Chewing the Scenery: Now with the new Barbarian emotes, you can SCREAM with bloodlust and ham with your arms spread wide and your mouth agape!
Color-Coded for Your Convenience: The Nationals and Royals clothing are all distinctly different, with Royal clothing having a larger portion of lighter greens and tans, and other "Good Guy" colors, while the Nationals have colder blacks, greys and blues - which likely contributed to the removal of National clothing that was forest green.
The accessory store has (very expensive) peacocks on sale, both for Royals and Nationals. The Royal variety looks like your typical Real Life peacock, whereas the National one is cyan, with blood-red tail feathers.
Also AFK killing. Killing a player who is standing idle while the person is away to do something for a minute.
And Noob Bashing. High-leveled players killing lower-leveled players.
Continuity Nod: Incidentally, to prior Battlefield games. Long before Heroes was even on the drawing board, players in Battlefield 1942 could be seen (if rarely) standing on the back of jeeps and tanks (the shape of the tank's turret also granting cover), and riding on the wings of airplanes (though, you'd fall off if the plane turned over.)
Cool Guns: While the Thompson is a perfectly common gun inside the WW2 setting of the game, the better level 10 version adds the rarely-used drum magazine with a grip on the front.
Composite Character: After a fashion — the three classes are each an amalgamation of the standardized classes from other Battlefield games.
Critical Hit: The damage multiplier of them varies, they appear in orange numbers and chances of them happening is pretty slim in a single firefight - unless you use Poisoned Blade for knives...
Does This Remind You of Anything?: The National Army...let's see...their flag is red, with a black skull and crossbones, they wear collared, buttoned jackets, and they have a red armband on their left arm in the concept art. Well?
Excuse Plot: The game's war has currently been explained to have been declared by the Royals on the Nationals after the Nationals took the gold in Olympic Cycling, making it even more Serious Business then it usually is (Oh, and a Royals' newspaper claims the Nationals mocked their king's mustache during peace talks).
There are occasional little side stories accompanying new stuff that the next patch will feature, even a small comic once, but they haven't gone very far and are entirely unneeded for enjoying said new stuff.
To be perfectly fair, it helps that most sources (including Nationalist ones) indicate the Nationalists cheated to win the race. And so obviously they must be punished for such unspeakable perfidy, right?
Military Maverick: The description of the Royal "Leet Hero" set spells it out quite nicely.
More Dakka: All the classes have some means to acquire an automatic (or burst fire) weapon for close quarters combat. This ranges from a pistol that's basically the Mauser C96 in Luger, Colt or Revolver form (unless it's the National version, which IS a Mauser C96), to machine guns that sound an odd amount like a minigun, with several variants of SMG sitting between them.
Ninja Pirate Robot Zombie: There are a variety of types of clothing to buy with real money, and nothing is stopping you from combining them.
No Celebrities Were Harmed: According to one of the loading screens, each class was based on a particular movie star. While it doesn't give details, the game encourages you to guess.
The Burly Bruce (Bruce Willis) and Savage Sly (Sylvester Stallone) sets are obvious enough that guessing isn't necessary.
The Smooth and Thuggin' sets are both based on Michael Jackson; specifically, his appearance in the "Smooth Criminal" and "Beat It" videos. Their original run as Valor Points clothing likely solidifies that they were to commemorate Micheal Jackson's death.
One-Hit Kill: Deliberately avoided as much as possible, though running over people with vehicles or shooting Commandos in the head with the most damaging sniper rifles while using the Piercing Shot ability may do so.
Parrot Pet Position: There are pets purchasable in the store that ride on the player's shoulder. (Royals get a monkey and eagle, Nationals get a king cobra, parrot and robot monkey. Both factions get snapping turtles and peacocks.)
PVP Balanced: Shooting a sniper rifle without aiming using its scope is incredibly inaccurate - it can somehow shoot a bullet behind your character. Most weapons also have an effective range which do less damage out of that range, whether too close or too far.
Reptiles Are Abhorrent: The "evil" army, the Nationals, have king cobras as pets, while the "heroic" army has a bald eagle.
Revolvers Are Just Better: The lvl-10 versions of pistols which have a better chance to critically hit and a larger magazine.
That's only the Royals. The Nationals get the completely different, stripper-clip fed Mauser C96 'Broomhandle' - which, if you think about it, is basically a Nazi Revolver.
RPG Elements: You have a set amount of characters you can make per account, you choose one to play with at a time, with their own persistance - they level up and choose the abilities they use and their effectiveness. It's like an MMO with no NPCs, though the game's currency is counted for your account rather then individual characters.
Rule of Fun / Rule of Cool : More or less the entire game - your Hit Points are far greater than in other Battlefield games to make it easier to survive, the third-person' allows you to look at your character, everyone has some capability of fighting tanks on their own, you are still awarded experience points based off your efforts instead of actual kills or point captures, you can ride on a plane's wing...
Rummage Sale Reject: This is a fairly commonplace among the players who shell out the BF necessary to completely customize a character's appearance. "Fashion Victim Awards" are held periodically to "honor" the most garishly clad Heroes, with their ridiculous get-ups going on sale at the Hot Deals section of the site.
One update added a "randomize" button to the Appearance section of the in-game store, which randomly selects items from each field for your character to wear. More often than not you end up with an at best laughable ensemble.
Scratch Damage: Averted with tanks, who require specific weaponry to damage them. Played straight with the prospect of using a gun out of its specialized zone (using the Long Range SMG close up, for instance), in that you'll do 1-6 damage per hit. Unless we're talking about sniper rifles, which do fairly good damage at all ranges.
Selective Historical Armoury: As one might expect from such a game, 'cooler' weapons are used, and rifles are only utilized with scopes - there are no guns that would have been more standardized in terms of being issued in WW2. No M1 Garands with only iron sights, M1 Carbines. Browning Automatic Rifles, Kar98s, M3 'grease guns', MG42s...
And then the Modern weapons come along and complicate matters even further. A Micro-Uzi?!
Sniper Pistol: Soldiers and Commandos may use a pistol which is one, but does less damage at a closer distance and the other pistols, made for closer ranges, are not. In fact, Soldiers' submachineguns are generally capable of hitting things from far away with reasonable accuracy, they just deal much less damage.
Speaking Simlish : The player characters don't actually speak all that much ingame, except for a muffled "Hello" (spoken with a stereotypical accent). For the most part, they just express themselves with overexaggerated interjections and gestures.
You can even use your hard-earned experience points to buy them new additional gestures. These are used either to suggest a new combat tactic to the others, call for help/backup, or taunt the enemy — especially immediately after you've killed one.
Spiritual Successor: Battlefield Play 4 Free, which is an updated version of Battlefield 2 with elements of Heroes and Bad Company 2. It's considerably less humorous than Heroes, but incorporates many of the same elements.
War Has Never Been So Much Fun: The game has generally bright environments, looks cel-shaded and has soldiers which hop around firing weapons with silly names, making muffled noises and exaggerated expressions while potentially dressed like werewolves, ninjas, zombies, paratroopers, something like Michael Jackson in a music video of his, knights, or everything in between.
White And White Morality: Neither faction actually seems to be bad. Nationals are generally more sinister in appearance, but that's about it.
Wronski Feint: It's possible to pull this off with a plane, though tricky. Usually, however, it is done not to trick your opponent into crashing their plane but to perform wingclips.
Standard Status Effects: Players low on health will have their health symbol flash red as a Critical effect, with further damage done against them to be seen as red numbers by the players who hit them.
Status Buff: Bandages Heal Thyself over time as a Regeneration effect, Wrenches does the same for the vehicle you're driving. Sarge's Stamina Boost is a static Max Health buff.
Aura Vision: Using the Mark Target ability to... mark a target... causes your team to see that target as a white outline for the duration of the ability if they normally would be incapable of seeing it.
Booby Trap: The Troop Trap can be laid down to damage enemies and vehicles alike, but may be shot from a distance to avoid them. An unwary Commando hanging around his own Troop Traps can easily find himself literally Hoist by His Own Petard if enemy fire swings his way and sets them off (or if they go undetonated for too long, in which case they go off on their own) — the explosion wouldn't do any damage in that case, but the fall might if he doesn't deploy his parachute.
Fragile Speedster: The Commando class moves the fastest out of all classes, and relies on its stealth ability and caution to stay alive. He becomes the Fragile Superspeedster when he uses his Elixir ability.
Glass Cannon: The Commando can do a high amount of damage at one time, but has the lowest amount of health of the three classes.
Katanas Are Just Better: Katanas were added in late November 2011 to complement the Heroes of the Rising Sun sets. They're the most powerful, longest-range melee weapons, though they swing much more slowly than the knife or the machete. And in case you were wondering, they're just as useless against tanks as any other non-explosive weapon.
Knife Nut: The knife is one of the signature weapons of the class and is actually pictured on the class insignia; very few Commandos go without one (or a machete at least)
Kukris Are Kool: The Halloween 2011 update featured the addition of machetes as a replacement for knives. The Royal machete is just that, but the National version is actually a kukri.
Status Buff: The Piercing Shot ability is a Strength one, but for sniper rifle shots. Elixir is a Speed one that increases movement speed (and provides a small shield that absorbs damage, effectively a Max Health boost much like Hero Shield). Poisoned Blade increases a knife's chance to Critical Hit by a considerable amount.
Standard Status Effects: The Poisoned Blade ability causes the wielder's knife to do extra poison damage over time. Troop Traps also have a poison effect on enemies.
Useless Useful Stealth: The Stealth ability is necessary to not get spotted and wiped out by the other classes if you play as Commando, with your low Hit Points...
BFG: The Gunner's schtick - running-and-gunning with what would be considered medium machine guns in real life (so, you wouldn't be able to do so in real life) and rocket launchers.
More Dakka: As redundant as it seems, Gunners, particularly those who build themselves around Double Machine gun builds, Generally using the accurate and rapid machine guns (The latter of which has names like the "Cheeser" or "Backscratcher").
Taken to extremes later on. The Super and Uber Machine Guns are a VICKERS and an M2 BROWNING, and the Super/Uber Rocket Launcher is SHIP CANNON.
And then they topped themselves again with the Drake's Fire/Dragon's Fire launchers, which actually fire huge cannonballs.
Exploding Barrels: Its own spin - instead of luring enemies toward one, or waiting until it's a really good time to shoot one, the Gunner class has a skill which allows them to throw explosive kegs that blow up after one shoots it. There are otherwise none in the game.
Lightning Bruiser: His only drawback is his speed...but that is remedied with the "Leg It" ability. Indeed, this is among the most-used of Gunner abilities.
Mighty Glacier: The Gunner class moves the slowest, but is very dangerous via frontal attacks alone.
Rocket Jump: With the added bonus of not hurting yourself and a parachute - it allows a Gunner to hop onto roofs and fire down on people below them. Often coupled with a barrel for added oomph, tossing the player considerably higher.
Status Buff: Leg It increases the Speed of you and nearby allies for a short time, and the Frenzy ability increases machine gun Accuracy and heals for every 4th hit while the ability is active (and damage at later levels, making it also a Strength buff). The Explosive Keg ability does the opposite of the Status BuffSpeed effect to those hit by it (It slows them down). Hero Shield is a Health buff in that it creates a shield that effectively increases the Gunner's maximum health.
