''Heavy Barrel'' is a 1987 overhead RunAndGun UsefulNotes/ArcadeGame by Creator/DataEast. It was ported to the UsefulNotes/{{NES}} in 1990.

[[ExcusePlot Terrorists have seized the underground control complex of a nuclear missile site, and it is up to one or two players to infiltrate the base and kill the enemy leader]]. Improved weapons and grenade powerups are made available within the game, either in plain sight or within crates that must be unlocked using keys. Additionally, crates may contain orbs or one of the six pieces of the [[{{BFG}} Heavy Barrel]] [[GameBreaker superweapon]].

The Heavy Barrel is [[IKEAWeaponry found in six pieces]] and is an energy cannon capable of destroying any enemy in the game with a single shot (except the final enemy, and possibly one other boss that may have required two shots). The weapon has a wide arc of fire and can be fired as fast as the player's trigger finger permits, but after 30 seconds (99 in the NES version) its use is exhausted, at which point the bearer reverts to his previous weaponry.

A similar game, ''Midnight Resistance'' was released by Data East in 1990, and ported to the UsefulNotes/SegaGenesis. It was often touted as a sequel to ''Heavy Barrel'', due to a similar control scheme (only with a side-view), graphics, and sound effects.
!!'''Tropes used for this game:'''

* {{BFG}}: The Heavy Barrel superweapon is definitely considered this. And a kickass one to boot it is an instant kill on pretty much every enemy except the FinalBoss (Who doesn't last that much longer anyway).
* BottomlessMagazines: Your weak starting weapon, and the Heavy Barrel. Unfortunately, the Heavy Barrel lasts for only 30 seconds.
* ChainReactionDestruction: Makes one wonder what kind of explosive material are concrete walls built of.
* DegradedBoss: The second stage boss (some elevator claw machine thing) appears as a miniboss in one of the later levels. And you have to fight ''two'' of them.
* [[DifficultyByRegion Difficulty By Console]]: The NES version is ''a lot'' easier then than the original arcade version.
* DisappearsIntoLight: Most normal soldiers die like this.
* DolledUpInstallment: [[http://www.youtube.com/watch?v=gcAtSdl8YcA Chip and Dale 3]], which is the NES version of ''Heavy Barrel'' except the player characters are replaced by WesternAnimation/ChipAndDale with guns!
* EpicFlail: The Hyper Ion Ball, a grenade substitute that whips around the user in a circle.
* ElevatorActionSequence: Many of the stages feature these (in fact, all the underground ones). Stage 2 has you fight a boss during one!
* FlashOfPain: Hitting stronger things brightens them up.
* FollowTheLeader: Data East's version of ''VideoGame/IkariWarriors''.
* IKEAWeaponry: In order to use the Heavy Barrel, you will need to obtain its six parts.
* KillitWithFire: The flamethrower weapon, arguable the best one to beat tough enemies and bosses with (excluding the heavy Barrel)
* MoreDakka: The Heavy Barrel weapon uses this to deal tons of damage. Would be a GameBreaker, if not for the fact that you can only use it for ''30 seconds''.
* OneHitKill: The Heavy Barrel against most regular enemies.
* OneHitPointWonder: Your character can only take one hit to die.
* OrbitingParticleShield: As shown in the picture
* SpreadShot: One of the improved weapons you could obtain. Getting red bombs also made your bombs explode in an eight-way burst.
* StalkedByTheBell: In the arcade version, taking too long in one area would result in multiple red bombs (which explode in a '''very deadly''' eight-way blast) continuously being thrown into the arena until you moved on or got killed. Worst of all, it can happen during the battle with the FinalBoss.
* SuperMode: Partially. When you get the HEAVY BARREL!!!, your attack becomes a devastating OneHitKill to most enemies, but you can still be killed normally.
* TheVeryDefinitelyFinalDungeon: Normally, there are two regular background musics, one used in [[http://www.youtube.com/watch?v=5OoYltfuKiU open air areas]] and another used in [[http://www.youtube.com/watch?v=wf0It_TQ7x0 underground levels]]. You know that you're in the final stage when the background music is ''[[http://www.youtube.com/watch?v=h6IUapSs3H4 this]]''.
* AWinnerIsYou: The ending is definitely this.
* WolfpackBoss: The bosses of the second-to-last stage are two robotic enemies that shoot fireballs at you. Later, you have to fight against three of them.
