* MakeMeWannaShout: The Screamers, one of the three base game special Zekes, unleashes ear-piercing screams that attract hordes of regular Zekes to you and your team. The only way to stop it is to kill the Screamers for good.

* ActionBomb: Bombers! Picture a crazy survivalist who loaded up on tactical gear and had no intention of succumbing to the virus; these guys wear panoramic night-vision goggles and a ''bomb vest''. They tend to announce themselves with a burst of garbled radio noise, followed by the beeping of their vest. The colors of the [=LEDs=] attached to their explosives denote how much time one has left to get out of dodge (yellow for 20 seconds, red for 5), or attempt a leg shot followed by a melee attack to defuse their bombs for some loot. Needless to say, having a Bomber blowing up in your face ''will'' hurt, as well as destroying any loot he might be carrying.

* AcceptableBreaksFromReality: Initially, only a handful of weapons could be silenced and the silencer itself came with various disadvantages to handling and damage. But after the GOTY edition patch, almost all weapons can be fitted with a silencer, with the disadvantages axed. Even such improbable ones as an anti-material gun or a double-barreled shotgun.
* ActionBomb: Bombers! Picture a crazy survivalist who loaded up on tactical gear and had no intention of succumbing to the virus; these guys wear panoramic night-vision goggles and a ''bomb vest''. They tend to announce themselves with a burst of garbled radio noise, followed by the beeping of their vest. Once the light on that vest turns red, there's nothing you can do to stop them from blowing up.

* ZombiePukeAttack: The recently added special Zeke, Infector, can only attack survivors with this, which is a [[OneHitKill insta-kill]] if the covered survivor doesn't clean it quickly via [[PressXtoNotDie button-prompt]].

** Juggernauts are similar to Bulls, except they knock over multiple survivors instead of grabbing just one, and have even more durability and no weak spot on their back.

** The Payload Rifle is what happens when you mix a Barrett M82 with .50 cal BMG Incendiary rounds, the result being a hefty weapon with enough power to kill scores of Zekes with ease at the bare minimum, and anything that isn’t killed from a bullet that can deal with a ''tank'' is turned into giblets and red mist by the following detonation of said round. Fixers can obtain a skill which increases its' magazine size and damage (maximum number of Zeke killed per shot) by 50%. Oh, and they also start the match with one of those on their back.

** Both Classic and regular Bullpup Rifles fire in burst and ''only'' in a burst. This means you have all the disadvantages of semi-auto (very slow rate of fire, unwieldy against hordes) and full-auto (massive use of ammo), without advantages of either.
** Prestige version of the Classic Bullpup Rifle takes it a step further. Once you are down to last six rounds in your mag, it receives a massive damage and penetration bonus. But since it's a burst-fire gun, that means two shots that only with perfect aiming and favourable situation will be anything else than total overkill of two targets. And then you have to reload anyway, making the power up a complete gimmick.

* DeadlyRotaryFan: During the finale of Jerusalem's last level, the squad can open up panels in the ground, temporarily revealing giant fan blades that chop up hordes.

** In the New York missions preview, we can hear a radio transmission from the United States Army that has prepared numerous amounts of artillery and other military hardware to annihilate the zombie hordes from New York and "just for the giggles". This brings up the memory of the Battle of Yonkers in the novel, where the US Army amassed a huge amount of military arsenals to defeat the New York hordes during the Great Panic, only to fail catastrophically.

** Snakebite SMG is a prestigious version of the regular, tier I SMG. You can empty the entire, 40-rounds magazine in ''one second''. It's as useful and practical as you think it is, given all ''other'' stats are unchanged.

* GunshipRescue: The JSDF manage to scramble a helo for the Cruise Ship finale, and it arrives to provide machinegun fire via one of the door guns towards the end of the final showdown.

* NeverSplitTheParty: The game is '''built''' on this trope. Get separated or lose track of your teammates and YouAreAlreadyDead. That said, the game ''is'' somewhat more forgiving in that regard than its inspiration ''VideoGame/Left4Dead''; a lone survivor has a decent chance of reacting to and handling the game's disablers, Lurkers and Bulls, whereas in ''Left 4 Dead'' disablers are more numerous, much faster, and much better at ambushes. Also, the durability of a Bull is aobut several dozen bullets, compared to the hundreds of bullets it takes to take out a Tank, so one can be handled by 1 or 2 survivors rather than requiring the whole group together. Large hordes during horde defense events ''will'' destroy separated survivors, though.

** Infectors have a projectile attack that can convert survivors into zombies if it's not dealt with quickly.

** Also, freshly zombified player characters or [=NPCs=] are ''slightly'' tougher than regular zombies, though the difference is fairly small.

* PeninsulaOfPowerleveling: With the "Horde Mode XL" update, the current fastest way to level up weapons is on the first stage of Moscow on the easiest difficulty where there's a ton of guns that spawn in the level that players can grab. Activate the defense horde mission, kill all the zombies until the experience needed for the gun that you are currently holding is maxed out, switch to a different gun found in the level, and repeat until all the guns that you have picked up are all maxed out. Then either just die or complete the mission and watch as the guns that you held all level up to the next level.

* AnAxeToGrind: Tashaun Burnell uses a fire ax as his melee weapon to kill Zekes that get too close to him [[JustifiedTrope Justified]] as he was a firefighter before the Zeke outbreak. The Aftermath update allows players to choose which melee weapon they want for any character.
