* CharacterSelectForcing: As the game progresses, each of the three main playable characters (Juno, Vela and Lupus) goes through a specific route of three worlds (namely two planets and one enemy mothership) to reach Mizar's Palace. But in those paths, they will find obstacles or {{Locked Door}}s that can only be overcome with a character other than them (for example, Juno goes through Goldwood and finds a chasm that can only be traversed by Lupus with his JetPack flight, Vela goes through Sekhmet and finds a tunnel in a lava foundry that can only be traversed by the fireproof Juno, Lupus goes through Eschebone and finds a submerged entrance that can only be accessed by Vela, and so on).

** Eschebone is a LethalLavaLand planet, and in its first level Lupus has to venture through many areas filled with lava while dealing with powerful enemies. Halfway in the level, however, he will find a giant worm he can enter through by knocking it out [[FeedItABomb by throwing a bomb at its mouth]]. From there, the level transitions into WombLevel and the second level follows suit (though the boss battle against the Mechantids takes place in a wide volcanic area accessed by [[ToiletHumor exiting through the worm's anus]]. Much later in the game, it's possible to access to the third level, which takes place inside the worm's spinal cord plus the central nervous system, complete with [[ConspicuousElectricObstacle several electrical hazards]].

* SpaceZone: Despite its intergalactic setting, the game takes place primarily on different planets and the interior of large space vessels. As such, the only two levels that properly display this setting are the Spacestation (a wrecked, derelict vessel stranded in outer space) and the Asteroid (the one Mizar is taking to planet Earth, and also the VeryDefinitelyFinalDungeon).

* SoundtrackDissonance: A few strange examples:

** The underground cave in Water Ruin is a short run down a corridor to a hidden ship part, with no combat taking place or mechanical elements on show, yet here the S.S. Anubis theme plays with its dramatic melody and soundscape evocative of the mechanical level it's usually heard in. These three cases would double as LongSongShortScene if it weren't for the fact that they are all heard in full (and more sensible contexts) earlier in the game.
** During Asteroid, the unique and climactically urgent sounding theme is replaced by the theme of Eschebone for a single room - while Eschebone's theme becomes plenty dramatic as it goes on, you're unlikely to spend long enough in the room to reach that point, making it ill-fitting.

* UnderTheSea: Water Ruin, a planet that consists of a very large body of water, and has its ground parts destroyed due to the BugWar.

* SoundtrackDissonance: A few strange examples - during Walkway, a level with no music otherwise, the Rith Essa theme plays during the elevator ride back up to the surface, barely getting started before the 5 second ride is over.

Finally, the underground cave in Water Ruin is a short run down a corridor to a hidden ship part, with no combat taking place or mechanical elements on show, yet here the S.S.

A third-person shooter released by Creator/{{Rare}} in 1999 for the UsefulNotes/Nintendo64.

In December 2023, the game was added to the catalogue of UsefulNotes/Nintendo64 games available for the expanded subscription plan of the UsefulNotes/NintendoSwitch.

* EternalEngine: The game has the three cargo ships that are stormed respectively by the three main characters: S.S. Anubis (Juno, though Vela tried to take control over it until she was kidnapped), Sekhmet (Vela, this time succesfully) and Spawnship (Lupus). These serve as the dungeon levels of the game. There's also the Spacestation, a wrecked vessel that has been stranded in outer space for a long time, but it's only accessible during the latter half of the game and plays more like a MiniDungeon.

* TheFederation: The Federation, although only briefly mentioned in-game and in the manual.

* FinalBossPreview: When all three playable characters arive Mizar's Palace and enter the pyramidal spaceship of the eponymous BigBad, one of them (Juno) watches Mizar approach and tries to confront him with his standard pistol. Mizar laughs at him and then throws him an energy ball that incapacitates him, and then leaves. The other two characters (Vela and Lupus) confort him as he stands up again, and all three go forward to face the villain together. Surprisingly, Lupus manages to defeat Mizar alone, since the latter only intended to toy with him for the sake of intimidation; realizing this mistake, Mizar does a RageQuit and begins a plan to destroy Earth, kickstarting the second half of the game.

* HailfirePeaks: Eschebone is both LethalLavaLand and WombLevel.

* SingleBiomePlanet: Several planets have each a specific ecosystem that is common in their global geography. They are, in order of appearance: [[TheLostWoods Goldwood]], [[BubblegloopSwamp Tawfret]], [[ShiftingSandLand Cerulean]], [[GhibliHills Rith Essa]], [[LethalLavaLand Eschebone]], [[GreenHillZone Gem Quarry]], [[LevelInTheClouds Walkway]], and [[UnderTheSea Water Ruin]]. It's unclear if this also applies to Ichor, whose playable parts take place inside the Drones' military facility (thus being RemilitarizedZone levels), so we don't see how the rest of the planet is like (one of the last areas prior to the boss room suggests it's a blue desert like Cerulean, whose orbit happens to be close to Ichor's). The remaining levels are EternalEngine vessels (S.S. Anubis, Sekhmet, Spawnship and Spacestation; the last one doubles as GhostShip), Mizar's Palace (a TempleOfDoom), and Asteroid (the final level).

* NintendoHard: Since the game is a platformer-shooter hybrid on the UsefulNotes/Nintendo64, the controls can be quite cumbersome to deal with while enemies move around rapidly and try to riddle you with bullets. Explosions also eat up your health like crazy, so you can bet the game starts putting explosive-wielding-foes-around-corner surprises. And the CompilationReRelease in ''Rare Replay'' bringing more somewhat-modern controls to the table don't mitigate the difficulty.

* MsFanservice: Being the only female cast member, Vela was likely designed with a ''[[MostGamersAreMale certain audience]]'' in mind. She wears no helmet so we can see her blue hair, has a neckline along with the usual assets and of course a tiny skirt that gives panty shots (until she's upgraded, then she's wearing shorts).

* TheVeryDefinitelyFinalDungeon: Mizar's Asteroid, which can only be accessed when the legendary Tribal ship is fully repaired.

* TwentyBearAsses: The game requires you to collect Drone Heads to activate "cheats", which are just gimmicks really. 100 Drone Heads give you Rainbow Blood, 200 give you Jet Force Kids (younger-looking versions of the main characters), and 300 give you... wait for it... Ants As Pants! Yes, Rareware's mascot Mr Pants replaces all the regular Blue Ant Drones. However, you have to kill the drones in the correct way, or you can't collect their heads. You must either shoot their heads clean off with a weapon such as the Pistol, Machine Gun or even the Shurikens, or blow them to bits with explosives (which has the added bonus of making blood and body parts fly EVERYWHERE, making it somewhat hard to see where the head has gone if it bounces off the top of the screen while many other limbs and splashes of blood are flying around). For extra difficulty, to unlock the cheats, you must reach the thresholds ''with the same character'', which means the Mr Pants requires you to gather 300 heads with ''one'' character; the accumulated amounts between the three characters do not count.

** Jet Pads: Only usable after Juno and Vela have their armors equipped with {{Jet Pack}}s and Lupus' jet engines in his feet are enhanced, these pads provide fuel to the pads/engines to fly upward; if they run out of fuel, the pads can be stood on for a recharge. The pads' border marks are yellow as well.

%% * GettingCrapPastThe Radar: Due to overwhelming and persistent misuse, GCPTR is on-page examples only until 01 June 2021. If you are reading this in the future, please check the trope page to make sure your example fits the current definition.

* {{Bowdlerise}}: In the Japanese release, some violent elements of the game were changed. The tribals [[AlienBlood bleed blue]] instead of red, and you can't behead tribals and Drones at all.
