[[http://www.remar.se/daniel/herocore.php Hero Core]] is a {{Metroidvania}} ShootEmUp game by DanielRemar, the creator of VideoGame/{{Iji}}. It uses old-school [[DeliberatelyMonochrome black and white graphics]] and 8-bit music to relate the never-ending war between Flip Hero and the Warmachine Cruiser Tetron. Though [[NintendoHard quite hard]], it's a high-quality game with numerous bosses and endings.

Hero Core is also the sequel to an earlier game called Hero, also by Daniel Remar.

----
!!Hero Core contains examples of:

* ArchEnemy: Flip Hero and Cruiser Tetron.
* AttackItsWeakPoint: Almost every boss has these little circular bubbles for weak points. You quickly get used to spotting and destroying them. If you can't see any, [[BoomHeadshot shoot its head.]] Only a very few bosses subvert this pattern, and those are all about your size. The Annihilator has a second. If you can't hit the head because it's facing away from you, [[spoiler:shoot for the tail!]]
* AttackReflector: The Blade. Apart from cutting through dirt and metal, it allows you to reflect some of the enemies' shots. The reflected shots don't hit the enemies, but the Blade itself inflicts damage.
* BigBad: Cruiser Tetron.
* BittersweetEnding: [[spoiler:The threat of Cruiser Tetron is ended forever, but Flip Hero is dead as well.]]
** Doubly so since [[spoiler:the question of whether Cruiser Tetron created Flip Hero to try and kill himself for good or Flip Hero went rogue]] is never answered directly. If it's the former, [[spoiler:then the ending is bittersweet for both Flip Hero and Tetron!]]
* BonusDungeon: The Annihilation mode is one of these.
* BootstrappedTheme: "Annihilator Factory".
* BossBattle:
** AnticlimaxBoss: [[spoiler:Cruiser Tetron]] is actually quite easy compared to some of the other bosses. [[spoiler:The Living Warmachine]] can be, too.
** BonusBoss: [[spoiler:The Living Warmachine.]] [[white:(As well as Zero, the level 0 specialist)]]
** CoresAndTurretsBoss: Rocksmasher, Liquid Metal Processor, Grand Mother, and Star Splitter.
** CowardlyBoss: The Eliminator[=/=]Hunter-Killer.
** DualBoss: The Elites. Also [[spoiler:a MirrorBoss]].
** FlunkyBoss:
*** The Reaper Drone takes this to its logical extreme.
*** The Grand Mother is this on multiple levels -- it spawns Mothers, which are themselves {{Mook Maker}}s. The Guardian also has statues at the top of his room that come to life after you damage him enough, and the Liquid Metal Processor is a more standard example. Seems like Daniel really likes this trope.
** GetBackHereBoss:
*** The Eliminator. It [[CowardlyBoss even leaves the entire room after a certain time limit]].
*** The Reaper Drone at some points, especially if you can't kill his mook swarms before he starts moving and becomes lost in the crowd.
** SequentialBoss:
*** The Star Splitter, Guardian, and [[spoiler:Tetron]].
*** Plasma Hydra is a variation of this. Blow off one head, out pops the next! Fortunately, at most 3 heads in a row pop up (in Normal mode, that is). So, not quite sequential boss, but a case of sequential boss targets.
** ShieldedCoreBoss: The Liquid Metal Processor.
* BossInMookClothing:
** Annihilators take a ton of hits to kill, and spam absurd quantities of bullets.
** Warp Eidolons make creatures while floating around and [[BeamSpam spamming lasers]].
** Nodes on hard difficulty, spamming lasers as well, being surrounded by orbiting spheres and quite tough.
* BossRush: With hard-style bosses, as a bonus feature. As of 1.2, a version with (slightly powered-up) normal-mode bosses is possible as well.
* BrutalBonusLevel: Annihilation.
* BulletHell:
** Hard mode has elements of this. You can do this as well to a limited extent if you find the Expel ability. Just make sure to [[CastFromHitPoints keep an eye on your health]].
** Though the Plasma Hydra boss fight has shades of this, it becomes ridiculous in Hard mode.
** Annihilation's final boss fight.
** [[spoiler:reallyjoel's dad.]]
* CanonWelding: [[spoiler:Annihilation mode will seem familiar to fans of Daniel Remar's other big game.]]
** Subverted; the fact that [[spoiler:Annihilation takes place on the Ciretako]] ''looks'' like it's supposed to make [[spoiler:''Hero Core'' canon to ''Iji'']], but in his official guide, Daniel states that Annihilation mode isn't canon and [[TheWalrusWasPaul he just did it to get people wondering about it.]]
* CaptainSpaceDefenderOfEarth: Flip Hero.
* CastFromHitPoints:
** The Expel ability. [[spoiler:Applies to the Elite bosses, too. If they try to expel with one hit point, they can't -- they only get a question mark over their heads.]]
** The ultimate weapon of the BonusBoss is also this. [[spoiler:Because it's the [[InfinityPlusOneSword Massacre]], a weapon [[ShoutOut from Iji]] that also [[CastFromHitPoints Casts From Hit Points]] in that game.]]
* ChestBlaster: The [[HumongousMecha Guardian]] has a laser and something which obviously is a [[VideoGame/{{Iji}} MPFB Devastator]] built into its torso.
* CollisionDamage: Flip Hero suffers from this. [[spoiler:So do the Elites.]]
* {{Combos}}: How Expel is triggered. [[spoiler:↑↓←→ then either fire key.]]
* CutSong: Both the Core theme and the boss music have completely different alternate versions. Neither are used throughout the game.
* DestructibleProjectiles: Homing missiles.
* {{Determinator}}:
** [[spoiler:Cruiser Tetron could be this. His last stage involves him being barely able to fight, and only able to lift his gun briefly, but he's still shooting.]]
** [[spoiler:The normal ending reveals that Flip Hero hunts down Tetron again and again to protect earth, even though he rebuilds every time he's defeated -- unless Flip Hero finds the way to finally destroy him.]]
** Anyone who has completed [[NintendoHard Hard or Annihilation difficulties]] without cheating.
* DoorToBefore: When a destroyed Generator lowers a nearby Barrier, it will occasionally create a shortcut to a previous room.
* EasterEgg: Oh so many. [[color:white:The Best Times room, Expel, Shapeshift, the Zero Specialist, reallyjoel's dad mode, Trollis' grave...]]
* EliteMook: The Elites and the Hunter-Killer are powered-up versions of lesser enemies. [[spoiler:They offer a clue, and the ending reveals, that Flip Hero himself ''is'' one.]]
* {{Foreshadowing}}:
** One boss fight sets you against [[spoiler:near-perfect copies of your character.]] This plays a part in the Good Ending.
** The hidden mode is called [[spoiler:Annihilation]] for a reason...
* GenreThrowback: To late-70s, early-80s video games.
* GoodBadTranslation: The "retro" language [[IntentionalEngrishForFunny imitates this]].
* HarderThanHard: Annihilation (although it's easier than hard mode, really). [[white:Parodied with Reallyjoel's Dad mode.]]
* HealthDamageAsymmetry: Not actually in means of damage, but in means of fire rate and intelligence. Bosses -- with the elites (128 HP each) as the most striking example since [[spoiler:[[MirrorBoss Flip Hero is otherwise identical with them]]]] -- have health ranging from 50 or so to some hundreds of hitpoints, while Flip Hero has only 10-20.
* HereWeGoAgain: [[spoiler:In the normal ending.]]
* HeroicSacrifice: [[spoiler:In the good ending.]]
* HeWasRightThereAllAlong: You have to enter one boss room before he gets violent.
* HumongousMecha: The Guardian boss. Also [[BigBad Cruiser Tetron]] and Annihilators.
* ICannotSelfTerminate: [[spoiler:Cruiser Tetron is eternally locked in the cycle of dying at the hands of Flip Hero and being rebuilt and trying to destroy earth again. Killing him is the only way to end this, though it's questionable whether or not Tetron himself is a big fan of dying.]]
* IntentionalEngrishForFunny: One of the game's three language settings is "Retro!", and when selected it will display all messages and dialog in humorously-broken English.
--> [[CrowningMomentOfFunny This upgrade has increase my "level" 1. Remember eat vegetables also to grow strong.]]
* InterfaceSpoiler: Various questionmark items in the menu.
* InternalHomage: Remember VideoGame/{{Iji}}? Annihilation difficulty gives you a first-hand view of [[spoiler:Ciretako!]]
** ''Iji'' itself contained an homage to ''Hero'', the game to which ''HeroCore'' is a sequel.
** [[spoiler:Cruiser Tetron's second phase duplicates his attack pattern from the original Hero.]]
* KingMook: The Reaper Drone and Grand Mother.
* LavaPit: Averted. Lava (molten metal) can be flown through freely and only serves to shut down your weapon for a period of time.
* LevelDrain: To [[AvertedTrope avert]] this, Flip Hero didn't gain any levels and equipment upgrades before fighting his way through Tetron's asteroid. Which is why Annihilation is a MinimalistRun and LowLevelRun...
* LuckBasedMission: The behavior and fire patterns of several enemies is random. For instance, fighting the Guardian or an Annihilator-with-mook on hard mode is a lot easier if you get lucky with their movement.
* MascotMook: The Drone.
* MercyKill: [[spoiler:The final fight against Cruiser Tetron is implied to be one of these, as you free him from the endless cycle of hate that he's locked in. It's really driven home by the final form, where Tetron is unable to even stand, limited to lying prone in the corner and feebly trying to hold up his arm to shoot you.]]
* {{Metroidvania}}: It's a blend of this and ShootEmUp. Also a slightly unusual example, as none of the upgrades are required to reach the final boss, though getting there without the item received for killing your first boss requires using a secret move.
* MinimalistRun: See {{Metroidvania}} above. Furthermore, a BonusBoss is only accessible on one of these. Annihilation mode is also this. You don't get any upgrades from bosses, and it's much more linear.
* MistakenForGranite: Guardian's room contains some statues of standard enemy machines you fought many times. Appearing to be decoration, they actually are idle machines and aid the boss once he loses a certain amount of HitPoints.
* MookMaker:
** Spawners, which were the only {{Mook Maker}}s in the original Hero.
** Mothers are archetypal for this; however, other foes [[note]]Hunters create Spews, Warp Eidolons create Phazes. The first boss casually creates some Drones.[[/note]] have this habit, even if they only create Mooks as a side effect of, for example, [[spoiler:firing their WaveMotionGun.]] One boss even ''spawns'' Mothers, making it a FlunkyBoss on multiple levels.
** [[spoiler:Tetron is this]] in the back story.
* MultipleEndings: There are at least two endings to the game. [[spoiler:Beating the game with all computers used gets you the best ending.]]
* NintendoHard: Normal mode is fairly easy, but Hard is brutal. Annihilation is worse.
* NonLethalKO[=/=]DeathIsCheap: For Flip Hero, who has a built-in restoration unit. [[spoiler:Also for Tetron, except in the good ending.]]
* OneBulletAtATime: There is a limit of six (non-Expel) bullets at a time.
* OneSteveLimit: Subverted.
* PowersOfTwoMinusOne:
--> [[foldercontrol]]

[[folder: REALLY ]]
\\
[[/folder]]

[[folder: THREAT LEVEL [[Harder Than Hard 255 ]]
]]
* RankInflation: In the boss rush, there are ''five'' ranks above A: [[spoiler:"Hero", "[[VideoGame/{{Tyrian}} Lord of Game]]", "You can stop now", "Seriously", and "[[MemeticBadass reallyjoel's dad]]". The last few aren't intended to be achievable, but Daniel Remar put them in based on the ridiculous performance of certain [[VideoGame/CaveStory Sacred Grounds]] runs.]]
* RecurringBoss: You have to destroy several Generators to progress, just like in the first. Also, the Eliminator/Hunter-Killer, who attacks many times until you are powerful enough to beat him.
* {{Retraux}}: Up to two colors simultaneously!
* RoboticReveal[=/=]AndThenJohnWasAZombie: [[spoiler:In the good ending]], although this probably wasn't a secret to the ''characters''.
* SequenceBreaking: You can bypass most of the game and get to the final boss with [[spoiler:Expelling]].
** MarathonBoss: Fittingly, the Plasma Hydra in Hard Mode. Also, Tetron and the Guardian.
* SeriesMascot: Flip Hero seems to be this for Remar Games, seeing as he gets referenced in a few other games that have nothing to do with him and appears in the Remar Games logo in the ''Videogame/GardenGnomeCarnage'' Flash version. In a strange variant of the trope, he's not even from Remar's most popular game.
* {{Speedrun}}: DanielRemar [[http://www.youtube.com/watch?v=0CcVj3-xnls made one for the Normal and Normal Boss Rush modes]], as he did for VideoGame/{{Iji}}.
* SoundOfNoDamage: A high-pitched "ding", which also fell under MostAnnoyingSound before its volume was reduced in an update.
* StationaryBoss: [[spoiler:Tetron's final form, which, aside from being awesome, also makes it [[AnticlimaxBoss incredibly easy]].]] Also, Generators and the Plasma Hydra.
* TheDevTeamThinksOfEverything: Open the badass savefile in a text editor and it will threaten to erase your data if you try to change anything - [[MundaneMadeAwesome IN SONG!]]
* TookALevelInBadass: Everything in Hard Mode, especially bosses. And ''especially'' the Reaper Drone.
* TurnsRed: Inverted with several of the bosses, as Daniel Remar dislikes cheap shots. That is, all bosses that have multiple phases start with the hardest one. [[spoiler:Unless it's the [[ThatOneBoss Plasma Hydra]].]]
* [[UnwinnableJokeGame Unwinnable Joke]] {{Difficulty Level|s}}: The highest difficulty level, called "Reallyjoel's Dad", that is [[http://www.youtube.com/watch?v=gfM3vtVlCTw almost]] impossible.
* UselessUsefulSpell: Both the Expel ability and the Blade are pretty much useless in combat. However, both have a specific function in speedrunning, and the Blade can slaughter certain enemies and bosses. [[color:white:Also, Shapeshift is mostly for fun]]
* WallMaster: The {{Eversion}}-like hands suddenly coming out of walls in Hero Forever. They don't damage you, but "just" steal your flags (that's bad already, though, since collecting flags is the point of Hero Forever) and will really creep you out the first time you encounter them.
** One of them even takes you to an easter egg in Annihilation mode.
* TheWalrusWasPaul: Daniel has stated that one of the main reasons Annihilation mode [[spoiler:is set on the Ciretako]] is to create {{Epileptic Trees}}.
* WhyWontYouDie: Found in some {{Apocalyptic Log}}s in Annihilation Mode.
