''[=MechAssault=]'' was a ThirdPersonShooter MechaGame developed by Day 1 Studios and published by Microsoft for the {{Xbox}} in November of 2002. ''[=MechAssault=]'' was initiated when Denny Thorley of Day 1 Studios approached Jon Kimmich of Microsoft about developing an original ''[=BattleTech=]'' game built from the ground up to support console play.

The game is set in the late 31st Century of the ''TableTopGame/BattleTech'' universe, sometime after the Word of Blake occupation of Earth in 3058. The PlayerCharacter is an unnamed VideoGame/MechWarrior of the elite [[NamesToRunAwayFromReallyFast Wolf's Dragoons]] [[PrivateMilitaryContractors mercenary company.]] Together with [[MajorlyAwesome Major Natalia Kerensky]] and [[TheEngineer Lieutenant Foster,]] the Mechwarrior [[SendInTheSearchTeam has been sent to investigate]] the [[DistressCall cessation of communication]] on the Periphery world of Helios. When they get there, their DropShip is shot down and they discover that the planet has been occupied by [[KnightTemplar the militant fanatics of the Word of Blake jihad.]] The team must salvage new gear, fight off the Blakeists and find out why they're on Helios in the first place.

A sequel, ''[=MechAssault=] 2: Lone Wolf'', was released on December 28, 2004.It picks up right where the first game left off, with the heroes recuperating on the planet Dante. The Blakeists soon make a return, in search of the MacGuffin that the team found in the first game. They soon meet up with a PirateGirl whose Jump Ship can take them to other planets, so they can pursue the Blakeists and find more [[MacGuffin MacGuffins.]] This installment added [[YouHaveResearchedBreathing the ability to get out of your 'Mech]] and into other 'Mechs, as well as battle tanks, [=VTOLs=], and PoweredArmor.

Both games featured online multiplayer over XboxLive in the form of modes like Deathmatch and CaptureTheFlag. The second game also had a persistent "Conquest" mode in which players battled for control of territories over the course of many matches.

There was also an installment on the NintendoDS, ''[=MechAssault=]: Phantom War.'' It is unrelated story-wise to the Xbox games, instead set many years later after the collapse of the HPG Network and staring a named protagonist, Mechwarrior Vallen Price. [[SoOkayItsAverage It was less well-received]] then the Xbox games, due to a lack of multiplayer and issues with the controls.
!!This game provides examples of:
* ActionGirl: Major Natalia Kerensky, your commanding officer, at least, [[InformedAbility she's supposed to be.]] She ends up being more of a BadassInDistress. She's a competent [[CoolPlane VTOL pilot]] if nothing else.
* AlphaStrike: An ability of all assault class mechs in the sequel
* BottomlessMagazines: Your weapons have unlimited shots unless you've upgraded them with a PowerUp. When that runs out, the weapon will revert to this state.
* BossInMookClothing: Enemy mechs can be this, especially when you're fighting multiple ones at once.
* CanonDiscontinuity: "Considered apocryphal", to quote the [=BattleTech=] wiki. This is in line with the policy of [=BattleTech=] canon in general, wherein any inconsistencies are considered to be [=ComStar=] deliberately screwing with the records.
* ChargedAttack: [[{{BFG}} PPCs]] work this way as opposed to a cool-down as seen in the ''VideoGame/MechWarrior'' series. The heavy missile weapons used by certain mechs, possibly Arrow [=IVs=], also work like this.
* CoolPlane: The second game has player-usable VTOL aircraft, armed with missiles and able to pick up and carry a variety of objects. This comes into play more so in the multiplayer, [[DeathFromAbove where they can carry bombs.]]
* CoverIdentityAnomaly: One mission in ''[=MechAssault=]'' has the player pilot a captured enemy Thor into a Word of Blake base to download some intel from their computers. The disguise almost works, until one of the Blake officers asks you to transmit your ID code or be fired upon. Fortunately, they wait just long enough for Foster to download the intel.
* DefeatEqualsExplosion: Even more so than the ''VideoGame/MechWarrior'' games. Every mech that dies explodes in a violent explosion and can easily cause a massive chain reaction if many others(even you) are near it
* DismantledMacGuffin: The Data Core found at the end of the first game proves to be one of a set of five, created by Jerome Blake, the founder of the [=ComStar=] company. Exactly what they contain is unclear, but they are used several times to [[PlugAndPlayTechnology supercharge current technology.]] This later becomes a plot point in the game's sequel.
* TheEngineer: Lieutenant Foster. He's a bit of TheDitz, but like many technicians in TheVerse, he can turn a pile of molten slag into a working BattleMech [[BigDamnHeroes in time to save your bacon.]]
* EveryoneCallsHimBarkeep: The protagonist is almost always just called "Mechwarrior."
* FeaturelessProtagonist: The main character of the original game. Averted in the sequel, which has him as a male HeroicMime. His eyes are hidden by a visor, though you can see them in the cover art.
* FinalBoss: The Ragnarok mech. Not only does it have Gauss Cannons, the best lasers, and a weapon called the ''magma gun'', it also has an energy shield. Later becomes BossInMookClothing when the final level of the second game has you fight multiple ones.
* FrickinLaserBeams: Pulse laser shots travel like your average "laser" projectile, while lasers shoot visibly-moving beams. Both types are, at least, as fast as bullets.
* GiantEqualsInvincible: Harmless infantry enemies are excused in that they're members a fanatical cult who aren't afraid to die.
* HoldTheLine: [[ExactlyWhatItSaysOnTheTin The level "Holding the Line"]] in the second game. You use a SentryGun to hold off incoming tanks and light mechs, but eventually things get hairy and you have to fall back to your DropShip- where foster has prepped [[WhosLaughingNow the Star Adder]] you recently salvaged.
* HumongousMecha
* IdiosyncraticEpisodeNaming: The second game's levels all have names.
* LethalLavaLand: The setting for the last six missions in the first game
* LostTechnology: The Data Cores likely contain Star League-era tech, given the fact they were created by the founder of [=ComStar=].
* MadeOfExplodium: Mechs,PowerArmor,Tanks,Buildings,Cars,Spaceships.It's guaranteed that a lot of things are going to explode throughout your playthrough
* MadeOfIron: Whatever those data cores are made out of, they sure will survive. The final one takes this UpToEleven when it survives [[HolyShitQuotient a spaceship]] getting dropped on it and doesn't even looked scratched.
* TheNicknamer: Natalia, who has names for the Mechwarrior and Foster. "Tiger" for the former.
* {{Overheating}}: As in ''VideoGame/MechWarrior'', weapons generate heat when fired, with EnergyWeapons generating much more then ballistics or missiles. Unlike in Mechwarrior, however, overheating your 'Mech will not force a shutdown or [[StuffBlowingUp blow it up-]] you will simply be unable to fire until the heat meter drops out of the red.
* PoweredArmor: Seen in both games, but pilotable in the second. Clan-type Elementals appear, as well as an experimental suit created by Foster with the help of a Data Core. In addition to a nasty mortar attack that can one-shot tanks, it has a "[=NeuroJack=]" feature that facilitates the hijacking of enemy 'Mechs.
* PowerUp: The most visible indication of this game's arcade-style nature, in contrast to ''VideoGame/MechWarrior''. [[HealThyself Green health pickups]] abound, as well as [[ColorCodedForYourConvenience blue, red and yellow]] ammunition pickups, which power up your energy, missile and ballistic weapons, respectively.
* PressXToDie: In the multiplayer Grinder mode if you play with a friend you are able to walk around as a regular human. Press a certain button? LudicrousGibs!
* PressXToNotDie: The hijack mechanic has you do this to eject the enemy pilot. It's also use to operate consoles while on foot.
* RealSongThemeTune: ''[=MechAssault=] 2'' has "Getting Away with Murder" by Papa Roach.
* RuleOfSymbolism: Invoked by Foster when trying to figure out where the last two Data Cores. He discovers that the star systems where each of the five were hidden form a constellation of the [=ComStar=] logo.
* SequelHook: How the second game ends. Sadly, [[ScrewedByTheNetwork a third is probably]] [[ExecutiveMeddling never going to get made]] because the [[AuthorExistenceFailure creator(Day One Studios) was bought out]].
* ShoutOut: There's a bunch in the level names in the second game.
** One of the last levels is an arena battle. The name of this level? "Film/{{Gladiator}} [[TakeThat has Nothing on Us.]]"
** One cinematic is called "[[TheWizardOfOz We're not in Kansas anymore.]]"
** Another is [[Franchise/IndianaJones I Hate Snakes]]
** Yet another is [[Music/ThePolice Sending out an SOS to the world]]
* SkeleBot9000: The FinalBoss of the second game is what looks to be an unholy fusion of an ''Atlas'' and the [[spoiler: human reaper embryo]] from ''VideoGame/MassEffect2'', and it's supercharged with ''all five'' Data Cores. It looks scarier then it is, though- the strategy to defeat it involves AttackItsWeakPoint and the aforementioned hijack mechanic.
** Then again, it ''is'' only about 1/3 finished, with no pelvis or legs. Presumably if it had been finished, it would have been an absolute unmitigated ''terror'' on the battlefield.
* TanksForNothing: Enemy tanks are really only a threat in large groups, though the Rommel tanks you can drive are more effective. They sometimes come equipped with [[InvisibilityCloak "Null Sig"]] tech and have [[SniperRifle a zoom feature]] on their cannons.
* TooDumbToLive: It's a really, really bad idea to get out of your 'Mech or other vehicle if there are any enemies around. Naturally, [[ButThouMust you HAVE to]] [[StealthBasedMission in certain areas.]] You have demolition charges, and enemies cannot see you unless you're literally right in front of them, so it's not as bad as it sounds.
* VideoGameCrueltyPotential: You can kill random groups of infantry who are TooDumbToLive in many ways: [[MoreDakka Machine Guns]], [[NoKillLikeOverkill fully upgraded missiles]] or just walk right over them.
* VoiceWithAnInternetConnection: Both Kerensky and Foster.
