Metroid (video game)

Nintendo · 1986

Metroid invented the 'ability gate' — but it gives you no map, no hints, and no mercy.

Metroid (1986) is a foundational action-adventure game where Samus Aran explores the planet Zebes, acquiring abilities like the Morph Ball and Screw Attack to unlock new areas. It uses nonlinear progression, mandatory boss fights (Kraid and Ridley), and a password save system. It is one of Nintendo’s major franchises and features Samus Aran, a Nintendo character with international recognition.

    A Planet Made of Doors

    You move Samus through hand-drawn 2D caverns on Zebes — a world built from doors, elevators, and looping geography.

  2. 2:35
    Abilities Are Architecture

    Every power-up changes what your body can do: curl, bomb, somersault — each unlocks a new kind of space.

  3. 3:46
    Bosses Are Keys

    Kraid and Ridley are hard stops — not story beats, but physical locks requiring specific tools to break.

  4. 4:44
    Combat Is Resource Mining

    You hunt Space Pirates not for plot, but for resources — energy, missiles, and the slow expansion of your own capacity.

  5. 5:43
    Exploration Is Recursive

    Backtracking isn’t filler — it’s the core act. You return not to fight again, but to see the same room with new eyes.

Worth your time?

Yes. Play the whole thing.

4/ 5
What works
  • establishes tight cause-and-effect between ability and access
  • makes geography feel physically consistent across revisits
  • turns boss fights into structural milestones, not just combat tests
  • uses enemy drops and storage tanks to scale player capacity meaningfully
What does not
  • gives map or navigation aid
  • provides tutorial or contextual hinting
  • offers session continuity beyond passwords
  • uses narrative to motivate progression
Play it if
  • players who treat environments as logic puzzles
  • players comfortable with ambiguity and repetition
  • players interested in the origins of ability-gated design
Skip it if
  • players needing clear goals or feedback loops
  • players who dislike backtracking without spatial payoff
  • players expecting modern UX conventions
The written brief2 min read

What the game is

Metroid is an action-adventure game set on the open-ended planet Zebes. Players control Samus Aran as she hunts Space Pirates through interconnected 2D caverns. Progression is gated by permanent power-ups that expand movement and combat options. It is one of Nintendo’s major franchises and features a Nintendo character with international recognition.

How it actually plays

The player controls Samus Aran in sprite-rendered 2D landscapes on the planet Zebes. She begins with only a weak power beam and basic jumping. Progress requires exploring interconnected caverns, backtracking through doors and elevators, and collecting permanent power-ups — Morph Ball, Bomb, Screw Attack — to unlock new paths. Defeating Kraid and Ridley is mandatory. Enemies yield energy or missiles; storage tanks and boss victories increase carrying capacity.

What works

The loop is clean: explore → find ability → revisit old areas → uncover new path → repeat. Each power-up changes how Samus moves and interacts with space — Morph Ball enables vertical tunneling, Bomb reveals hidden architecture, Screw Attack rewrites combat rhythm. The planet feels cohesive because doors, elevators, and enemy placement reinforce geography. Bosses Kraid and Ridley are distinct physical obstacles, not just damage sponges.

What does not

It offers no guidance. No map. No quest log. No visual feedback for hidden walls or passages beyond trial-and-error bombing. The password system forces repetition across sessions. Its nonlinearity is real but ungenerous: backtracking is frequent, and dead ends are indistinguishable from locked zones until you acquire the next ability.

Who it is for, and who it is not

It is for players who enjoy solving environmental logic puzzles with their bodies, not their eyes. It rewards observation, pattern recognition, and willingness to retrace steps. It is not for players who need signposting, narrative scaffolding, or immediate feedback. It assumes competence, not mastery.

Is it worth your time

Yes — if you want to experience ability-gated exploration before it had a name. It asks for patience, spatial memory, and tolerance for opaque progression. It does not ask for reflexes, speed, or precision timing. Its value lies in its structural clarity, not its polish.

Armored Core (video game)FromSoftware · 1997Armored Core (1997) is FromSoftware’s first mecha combat game. Players pilot highly modular Armored Cores across open desert bases and space stations, engaging enemies that appear from all directions. Customisation is functional: swapping leg units changes mobility; weapon choices define combat range. Credits earned from missions fund upgrades, but ammunition and repair costs are deducted even on failure. There is no hand-holding — no map, no waypoints, no enemy indicators. The loop is austere, spatial, and penalised.

Ecco the Dolphin (video game)Sega · 1992Ecco the Dolphin is an action-adventure game where the player controls a bottlenose dolphin navigating time-traveling plot-driven levels. Core mechanics include speed-based swimming, singing-based interaction and mapping, glyph-based puzzles, and survival constraints like air depletion and health management.

Kangaroo (video game)Sun Electronics · 1982Kangaroo is a tightly wound 1982 arcade platformer where vertical movement, joystick-based jumping, and face-to-face punching define every second of play. It delivers immediacy and clarity at the cost of variety and longevity.

Lost Ark (video game)Smilegate · 2018Lost Ark is a technically competent, gear-obsessed PvE MMO that delivers satisfying combo combat and vast content—but only if you accept its rigid, repetition-first design as a feature, not a flaw.
