''Havoc'' Is a little-known FirstPersonShooter by defunct developer Reality Bytes, released in 1995. They made only two other games: a Mac-only VideoGame/{{Doom}} clone called Sensory Overload before Havoc, and a third-person HackAndSlash fantasy game called Dark Vengeance, after Havoc. It was advertised as a KillerApp for Windows 95, pushing that OS's graphical and networking capability. In the vein of ''VideoGame/{{Battlezone|1980}}'', Havoc put players in control of a combat vehicle and pitted them against hordes of foes.

The singleplayer campaign cast you as a sort of land-{{Pirate}}, a freelance [[UniversalDriversLicense tank commander]] wandering the battlefields of a [[AfterTheEnd post-apocalyptic Earth]] ruled by [[MegaCorp Mega Corps]] in search of useful loot and supplies. Your enemies are the {{Mooks}} of Tyrakian Global, one such MegaCorp. Their forces are spread across three major regions: The [[DeathMountain mountainous, rocky]] Badlands, the [[SlippySlideyIceWorld frozen Fallen Wastelands]], and the [[EldritchLocation bizarre,]] [[AmazingTechnicolorBattlefield colorful]] [[TheVeryDefinitelyFinalDungeon Tyrakian Territories.]] In each level, there are three [[MacGuffin Gate Keys]] to find, each guarded by a powerful SentryGun and numerous other foes. Find the keys, then find the exit. Do this for three levels and [[BossFight fight a boss]]. There are over 30 levels total and six Bosses. You have a ''wide'' variety of weapons to use, and a choice of three vehicles.

For its time, the game incorporated a number of cutting-edge features: Varied environments and terrain, terrain deformation, support for [[GogglesDoSomethingUnusual virtual reality goggles]] of the time, and cross-platform multiplayer between PC and Macintosh. The game worked on either system out of the box, and came with a multiplayer-only second disc that could be given to a friend. If you had enough discs to go around, 16-player deathmatches were possible.

[[IThoughtItMeant This game shouldn't be confused with]] either film called Havoc. Or the [[WreakingHavok Havok physics engine.]]

!!''Havoc'' provides examples of:

* AlienSky: In the Tyrakian Territories, the sky is pitch black.
* BonusStage: There's a bonus level after every BossFight. Collect [[PowerFloats floating]] [[PowerCrystal crystals]] and "HAVOC" letters for [[ScoringPoints bonus points.]]
** BrutalBonusLevel: It's incredibly difficult to actually gather all the crystals ''and'' letters, though this isn't necessary to progress.
* BossFight: Six total. Each is a different vehicle with wildly differing weapons and behaviors.
* CarFu: [[SubvertedTrope Subverted]], unfortunately. Ramming enemies ([[MalevolentArchitecture and terrain]]) tends to just damage your car without doing appreciable damage to them.
* CompetitiveBalance:
** FragileSpeedster: The green [[CoolBike BattleCycle.]]
** JackOfAllStats: The red [[HoverTank HoverCraft.]]
** MightyGlacier: The blue [[TankGoodness HyperTank.]]
* DeflectorShields: Your vehicle has these, though [[CallAHitPointASmeerp they're really treated]] as HitPoints.
* DeadlyDisc: [[ExactlyWhatItSaysOnTheTin The Disc Gun.]] Notable for it's very distinctive firing sound.
* DeathFromAbove: The powerful mortar cannon gives you indirect shelling capability. [[AwesomeButImpractical Its fairly hard to use, though.]]
* EldritchLocation: The Tyrakian Territories, seen in worlds [[DiscOneFinalDungeon 3]] and [[TheVeryDefinitelyFinalDungeon 6]], are markedly different from the other two zones. AlienSky, AmazingTechnicolorBattlefield, {{Bizarchitecture}} and [[AnimalMecha enemies resembling animals]] can all be found here, as can the game's two oddball bosses: [[EnergyBeings A living cloud of flame]] and [[spoiler: The [[OurDragonsAreDifferent Tyrakian]] [[BigBad Overlord.]]]]
* EnemyDetectingRadar: You have a convenient minimap in the lower-right of your HUD. Targets are ColorCodedForYourConvenience: Land enemies are red, air enemies brown, [[SentryGun sentries]] blue, static structures green.
* EnergyBeings: The third boss is a giant, living cloud of flame that spits fire at you.
* EnergyWeapon: The primary weapons are all this. In general, they possess a rapid fire rate and [[BottomlessMagazines infinite ammunition.]]
* {{EMP}}: The first boss fires projectiles at you that scramble your targeting and radar.
* FlashStep: The second boss can teleport around in addition to ordinary flight.
* FrickinLaserBeams: You begin the game with [[EmergencyWeapon a weak red laser gun.]] One PowerUp you can find makes it [[LawOfChromaticSuperiority blue and stronger,]] while another nets two lasers per shot.
* ImprobableAimingSkills: Of a sorts. A certain PowerUp vastly expands the range of the targeting brackets on your HUD, temporarily. Your shots auto-track enemies you keep within these brackets.
* InvincibilityPowerUp: The "Ultrashield" PowerUp has this effect.
* KillItWithFire: The slow-firing (relatively), but high-damage FireBall gun.
* LandMineGoesClick: A Thermite Mine dropper is available as a secondary weapon. Watch out, as some enemies and bosses can also drop these.
* MirrorBoss: The fifth boss uses an identical vehicle and weapons to yours.
* PowerUp: A staggering variety: [[HealThyself Shield bonuses,]] [[InvincibilityPowerUp Temporary invulnerability]], new weapons, weapon upgrades and ammo, the "[[ImprobableAimingSkills targeting bonus]]" and others.
* ScoringPoints: The game tracks your score, arcade-style. [[SpeedRun You receive a bonus for finishing a level quickly,]] [[EveryTenThousandPoints and can earn extra lives at certain scores.]]
* SentryGun: There are quite a few of these found on the ground and on walls, and they typically deal a lot more damage then mobile foes. A [[EliteMooks stronger, larger kind]] guards each Gate Key.
* SlippySlideyIceWorld: The Fallen Wastelands, seen in worlds 2 and 5. Characterized by open clearings, large stalagmites and enemies with skis.
* ShockwaveStomp: [[ExactlyWhatItSaysOnTheTin The Shockwave]] secondary weapon. It fires a seismic pulse forward, much like the Thumper weapon in the later 1998 ''VideoGame/{{Battlezone|1998}}'' remake.
* StuffBlowingUp: Hoo boy. The secondary weapons are all [[StuffBlowingUp explosive]] or otherwise highly destructive in comparison to the primary weapons, but have limited ammunition. Still, they are vital to your success, so don't be afraid to use them. But be careful, [[HoistByHisOwnPetard shrapnel from explosions can damage your vehicle.]] Keep a good distance from your targets.
* RandomlyDrops: Curiously enough, the weapons, like other [[PowerUp Power Ups.]] This means you might get a DiscOneNuke or be [[MinimalistRun stuck with the low-damage laser]] for one or more worlds. In addition, weapons used by bosses do not become available to drop until after said boss is beaten.
* RemixedLevel: You revisit each of the three worlds.
* VideogameLives: You begin with three, ScoringPoints [[EveryTenThousandPoints can get you more.]]
