[[http://www.gearheadrpg.com/ GearHead]] is series of free ScienceFiction {{roguelike}}s that focus on HumongousMecha while still retaining some traditional DungeonCrawling elements.

Atypically for roguelikes, [=GearHead=] has plenty of important {{NPC}}s and a developed BackStory about the power struggles between totalitarian empires and opportunistic corporations. The game world is also remarkably open - the first game features several cities with factions to join and arena combatants to challenge. The games also utilise random plot generation for quests and main storyline alike - The Villain may be a criminal overlord in one game, and a totalitarian government's agent in the next.

The first game, [=GearHead=], focuses on the player creating a career in East Asia, near the fictional city of Snake Lake. The second game, currently under development, takes place in space instead.

!!Features examples of:

* AbsurdlySpaciousSewer: There's albino alligators in the sewers beneath Snake Lake. In fact, there's a small laboratory down there for studying them.
* AfterTheEnd: The Age of Superpowers ended in the [[NukeEm Night of Fire]], making most of the Earth uninhabitable. The Federated Territories are the largest chunk of inhabitable land in the world.
* AdvancedAncientAcropolis: The Ziggurat. Also a TempleOfDoom.
* AnimalMecha: Zoanids.
* TheAntagonist: Varies from game to game, but is always fairly dangerous. Typically somehow connected with Aegis Overlord.
* AppeaseTheVolcanoGod: One Pacific Islander tribe worships a volcano, and the village chief's virginal daughter is to be sacrificed to it. [[spoiler: Actually, it's an ancient LostTechnology supermecha that's mind-controlling the local villagers.]]
* BeamSpam: Averted. While energy weapons recharge automatically, overuse will cause them to heat up one's mecha.
* {{BFG}}: Omnipresent in the [=GearHead=] universe. Mechas commonly have big weapons, and some people carry personal scale weapons designed for taking out mechas.
* CharlesAtlasSuperpower: It's possible to build a BareFistedMonk who can tear mecha apart.
* CorruptCorporateExecutive: Elisha Kettel, though she's not the worst by any means.
* CriticalExistenceFailure: Averted. You can lose subsystems without dying.
* CyberneticsEatYourSoul: Spiritual characters tend to feel this way, though there is an in-game philosophy that allows you to reconcile spirituality with the loss of your humanity. If you haven't taken the trait, however, a spiritual character will suffer increased problems from cyberware rejection.
** Another trait, Cyber-Psycho, allows you to take rejection differently, damaging your mood and causing mental fatigue instead of physical rejection.
* DesignerBabies: In the backstory, the Idealists.
* DuctTapeForEverything: No matter how badly one's mecha is damaged, it can be fixed with enough duct tape.
* TheEmpire: Aegis Overlord. They are among the antagonists of the first game.
* EvenTheGuysWantHim[=/=]EvenTheGirlsWantHer: If you have the [[{{Bishonen}} Bishounen]] trait (which is actually gender-neutral), you can use Flirtation on both males and females to equal effect.
* ExperiencePoints: Somewhat atypically, experience can be obtained by using non-combat skills as well. Lockpicking and mecha repairing grant large amounts of experience, as do prayer and scientific experiments.
* TheFederation: The [[ExactlyWhatItSaysOnTheTin Federated Territories]].
* ForScience: [=BioCorp=]'s modus operandi.
* GeneticEngineeringIsTheNewNuke: The source of a lot of the monsters floating around the Territories.
* HollywoodAtheist: Due to MagicVersusScience, understanding the world through science precludes understanding the world through faith and meditation, and vice versa. (You can practice both skills, but your Spirituality-versus-Pragmatism meter will be "neutral" instead of having both strong faith and scientific understanding.)
* HumongousMecha: It is a mecha fighting game.
* ImpossiblyGracefulGiant: Any mech with MV 0 is literally as agile as a human.
* JackOfAllStats: Averted - a player who attempts to learn too many different skills will have to pay extra experience for training any of them, slowing their advancement.
* LevelScaling: Almost all encounters' difficulty is scaled according to the player's reputation. Loser players will not typically get to even try fighting strong bad guys.
* LostSuperweapon: A recurring element in the first game.
* LostTechnology: All over the place. About half of it is safe to use, if you're lucky.
* MacrossMissileMassacre: Swarm missiles.
* MagicVersusScience: Spirituality versus Pragmatism. This personality axis determines whether you understand the world through spirituality, mysticism and religion, or through science and reason.
* MagneticWeapon: Railguns and Gauss guns are both commonplace in [=GearHead=] universe.
* MegaCorp: Kettel Industries, [=BioCorp=], and [=RegEx=] from the first game. More in the second.
* MilitaryMashupMachine: A possible result of some tinkering with mecha designs.
* MundaneUtility: Riding a humongous death tank is a faster way to travel than walking.
* NamesToRunAwayFromReallyFast: [[spoiler: [[ClassicalMythology Typhon]].]]
* OneHitKill: Very common - several high-end weapons can total a mecha in one shot. This is also probably the reason why neither of the games enforces FinalDeath.
* RecycledInSpace: [=GearHead 2=]'s description in Ubuntu's package repository puts it this way:
--> gearhead - roguelike mecha role playing game
--> gearhead2 - roguelike mecha role playing game in space
* [[ReligionIsMagic Spirituality is Magic]]: Meditating at shrines can develop your experience and occasionally give you statistical boosts, especially in the Shrine Tour.
* ScienceFantasy: Some of the elements in the first game shade into this.
** Shrines have magical effects.
** [[spoiler: Ladon, the god of a Pacific Islander tribe, subtly manipulates the minds of the people into throwing their people into the volcano to be eaten. It's actually a gigantic pre-war superweapon.]]
** [[spoiler: The Ziggurat, an ancient technological structure from the Age of Superpowers, also functions as a memorial to the dead who are there, and the Shrine of the Heavens is at the top.]]
** Clan Ironwind has a prophecy about an outlander who will join the clan and lead it to greatness. [[spoiler: It is guaranteed to come true in some form, should you complete the quest (which is DummiedOut in the last release version). However, they mistranslated the prophecy, and [[ProphecyTwist it's impossible for the prophecy to come true in the way that they imagine it coming true.]]]]
* SideQuest: Some of these are precreated, others are generated based on the current situation. For example, citizens will offer mecha combat missions if they are under attack by a raider faction.
* SpiderTank: Arachnids.
* SplashDamage: Explosive weapons, naturally, can cause this. In a slightly different variation, weapons with the HYPER-flag deal the damage inflicted to the entire mecha, not just the targeted subsystem.
* SubsystemDamage: Mecha, animals, and humans are made out of individual body parts that can be specifically targeted. Destroyed parts need to be repaired before they can be used again.
* {{Transhuman}}: The Extropian philosophy is about abandoning one's humanity and upgrading with cybernetic implants.
* TravelCool:
** BaseOnWheels: Any walking or rolling mecha.
** CoolAirship: Any skimming mecha.
** CoolPlane: Any flying mecha.
** CoolStarship: In [=GearHead 2=], some mecha are spaceworthy.
* VirginPower: Subverted and parodied. TheChiefsDaughter is a virgin who is selected to AppeaseTheVolcanoGod, but virginity is not actually required. [[spoiler: If you "disqualify" her for the position, her father will sacrifice ''you'' to the volcano instead.]]
* WrenchWench: Hyo Lee, and you can also make your own character this.
* WretchedHive: Snake Lake Waterfront.
