In this game you are Rad Gravity, a futuristic heroic spaceman. A mad scientist disrupts the peaceful universe and it is your job to visit various planets to re-establish contact between all the worlds. Sights vary between verdant planets, lava pits and hazardous jumps, with gravity variations and craters.

  • Introduction
  • What it is: A sci‑fi platform‑adventure game where space hero Rad Gravity and the lone active Compumind (Kakos) try to re-activate the galaxy’s other Compuminds. Developed by Interplay and published by Activision on NES. (Manual, Wikipedia)
  • Why it matters: A Western‑made NES oddball with big ideas—planet hopping, an infamous reverse‑gravity world (Turvia), and a hub ship for free routing as you find coordinates. (Wikipedia, Take On The NES Library)
  • “This doesn’t look like an NES game” (Art & Presentation)
  • Western palette & shapes: Big, chunky sprites; loud neons on Cyberia; grime greens on Effluvia—reads more like Western computer art than Famicom house styles. (Take On The NES Library)
  • Discuss now: Use this opener to kick off a quick riff on Western‑developed NES titles that felt tonally different—e.g., A Boy and His Blob, Maniac Mansion.
  • What kind of media (movies/TV) is similar to Rad Gravity
  • Saturday-morning space opera: Scrappy hero + chatty computer buddy feels like Flash Gordon and Galaxy Rangers
  • Comic Book Manual Story
  • Premise: In the far future, galactic civilization ran on AI brains called Compuminds. Agathos, once a human, now a giant brain, rules over the galaxy. He turned the AI brains offline; only Kakos remains to guide Rad to re-activate the rest.
  • Release, Credits, & Context
  • Release: US Dec 1990; EU/AU 1991 (Mattel in AU). (Take On The NES Library)
  • Developer/Publisher: Interplay Productions / Activision. (Wikipedia)
  • Key creative / OST: Credits include Brian Fargo (design/program), Bruce Schlickbernd (art), and composers David Warhol & George Sanger. (Wikipedia)
  • Banter weave‑in: Cue a chiptune craft sidebar—play 15–20 seconds and compare Western NES sound to Capcom/Konami schools. Does Warhol/Sanger read “space opera” or “Saturday‑morning sci‑fi”? (Credits on Wikipedia)
  • Structure
  • Loop: Pick a world from the ship monitor, grab codes/parts, reactivate that world’s Compumind, beam out, unlock the next coordinates. (Manual)
  • Agency: You can discover multiple coordinates and route your own order (within reason) before the Telos finale. (Take On The NES Library)
  • Kit growth: Start with short-range saber, then blaster, crystal bombs, armor—small expansions that change how you tackle chokepoints. (GameFAQs – FAQs)
  • Discuss now: Is this closer to Metroid’s authored route or The Guardian Legend’s hub freedom? Where’s the sweet spot? (Refs: Metroid manual, Guardian Legend)
  • Planet‑by‑Planet Flavor (set pieces, quick tips, and built‑in segment ideas)
  • Planet identity via tilesets: Every world re-skins the rules with bold, readable motifs (cloud catwalks on Vernia, lava ledges on Volcania). (VGMaps – NES)
  • Cyberia — Neon corridors, turret lines, beginner secrets. (Manual, GameFAQs)
  • Effluvia — Toxic trash world; falling‑junk cadence; use vertical shafts to funnel enemies. (Take On The NES Library)
    • Banter tie‑in: “Trash‑punk 1990” — pollution chic across late‑’80s media and how NES palettes sell “gross” with a few tiles.
  • Turvia — Entire planet drawn upside‑down; gravity reversed. Inputs are normal but collision is mirrored—practice “ceiling” ledge checks. (Wikipedia)
    • Segment idea: Inverted Level Hall of Fame — compare to Strider’s ceiling boots and Mega Man 5 – Gravity Man’s flip where art stays upright. Which is kinder, and why? (Refs: Strider, Mega Man 5)
  • Sauria — Jungle with aggressive hatchlings; bombs trivialize nests. (Take On The NES Library)
  • Vernia — Cloud city; wind‑feel scroll and thin catwalks—tap jumps. (VGMaps, Take On The NES Library)
    • Segment idea: Wind levels we love/hate — bring in Ninja Gaiden II’s gust rooms for readability talk. (Ref: Ninja Gaiden II)
  • Asteroid Belt — Derelict ship interlude; pockets of low‑ceiling platforming. (VGMaps)
  • Odar — Underground maze; mark ladders mentally—lots of loopbacks. (Take On The NES Library)
    • Segment idea: Mapping on paper — compare to Metroid notebook maps from childhood. (Ref: Metroid manual)
  • Utopia — Two‑sided planet (surface/underside) with factory below; dead‑ends teach route logic. (Take On The NES Library)
  • Volcania — Lava timing + projectile spam; learn safe ledge stutter‑steps. (VGMaps, Take On The NES Library)
    • Banter tie‑in: Risk budget talk—compare to lava/attrition set‑pieces in other NES action (e.g., Castlevania’s clock‑tower‑style stress math).
  • Telos — Final planet; Agathos showdown after Compuminds are online. (General plot: Wikipedia)
  • Passwords & Progression
  • Passwords: Necessary. Whole game only has 1 life (GameFAQs passwords)
  • Soft order suggestion: Cyberia / Effluvia → Sauria / Turvia → Vernia / Odar → Utopia / Volcania → Telos. (Routing notes: Take On The NES Library, GameFAQs)
  • Difficulty & Mastery
  • Friendly Fire - Enemies can kill each other
  • Is there enough gravity manipulation to warrant the title?
  • Short answer: Mostly no—except Turvia.
  • Is there enough Radness to warrant the title?
  • Name & era tone: “Rad” is pure 1990 energy—quippy manual blurbs, neon cityscapes, and a hero with a saber
  • In practice: The attitude reads more goofy pulp
  • Segment angle: Define “radness” with a checklist (stunt, style, soundtrack sting). Does Rad hit 2/3?
  • “The music is terrible”
  • Fun Facts & Trivia
  • No Japan release: NES‑exclusive in the West (later EU/AU distribution). (Take On The NES Library)
  • Composer duo: David Warhol & George Sanger share credit—title track has a cult following. (Wikipedia)
  • Strider vibes: Press often compared Rad’s sword + upside‑down stage to Strider’s ceiling walk. (Wikipedia – Strider)
  • We’ve orbited every oddball planet. Do we land this one on the ESSENTIAL GAMES LIST?
