Gaming as a Portfolio Theme: Documenting Iterative Map Design from Arc Raiders

Stop showing finished screenshots—start proving how you think

Admissions teams and portfolio reviewers in 2026 are tired of beautiful final maps with no evidence of how they were made. If your application to a game program looks like a gallery rather than a laboratory, you’re missing the single most persuasive signal: iteration. This guide shows exactly how to document iterative map design—using screenshots, version notes, and playtests—so your game portfolio tells the full story of your craft, not just the polished result.

Why process-first portfolios win in 2026

Over the last two admission cycles (late 2024 through 2026), programs and hiring teams shifted from aesthetic assessments toward behavioral evidence: can the applicant iterate, test, and respond to data? Schools want designers who can lead a level from blockout to balanced play. That means your portfolio needs to demonstrate how you think, not only what you made.

• Evidence beats claim: A series of annotated screenshots + playtest reports proves you learned and improved—far more convincing than a single “final” map image.
• Telemetry is standard: By 2026, even student projects use basic telemetry dashboards to show player flow and choke points. Admissions take notice.
• Short-form video is essential: Reels that compress iteration into 30–90 seconds are common on review sites and bring process to life.

Arc Raiders as a process case study

Embark Studios confirmed multiple new maps for Arc Raiders in 2026, deliberately experimenting across sizes for different gameplay experiences. That public roadmap provides a real-world frame: studios keep older maps alive to test new ideas and learn from player data. Use that mindset for your portfolio—document versions, keep old layouts, and show what those retained iterations taught you.

Design lead Virgil Watkins: maps will be “across a spectrum of size to try to facilitate different types of gameplay.”

What portfolio reviewers want to see (short list)

• Clear problem statement and design goals for each map
• Sequential artifacts (blockout → mid-prototype → polish) with annotations
• Playtest summaries that connect changes to player behavior
• Version notes or dev-journal entries that read like commits
• Visual comparisons and short video walkthroughs/GIFs

How to document iterative map design—step by step

1. Start with a one-line design brief

Before you make a single screenshot, write a concise brief that sets measurable goals. Example:

Design brief: “Create a 12–15 minute co-op extraction map that encourages flank-based play, reduces frontal chokepoints by 30%, and supports three distinct sightline ranges.”

This brief becomes the anchor for every artifact you add to the portfolio—screenshots, playtests, telemetry, and notes should reference the brief directly.

2. Use version control and a consistent naming convention

You don’t need Perforce to start, but you do need consistency. Name your files and folders so reviewers can follow a timeline at a glance.

• Folder: Project_MapName_Year
• File prefix: MapName_v01_blockout.png, MapName_v02_midproto.mov, MapName_v03_balance_notes.md
• Dev journal entries: YYYY-MM-DD_MapName_v02—short summary

Why it matters: Consistent names let reviewers quickly reconstruct the sequence of design decisions. You signal discipline and reproducibility—key traits of a good designer. If you’re worried about secure storage or team workflows, check hands-on reviews of secure creative team workflows like TitanVault & SeedVault for examples of versioned asset protection.

3. Capture the right visuals at the right times

Don’t just take pretty shots—capture function. For each major version capture:

• Blockout wireframe: Overhead orthographic and first-person screenshots showing flow.
• Navigation maps: Heatmap of intended routes, labeled spawn zones, and objectives.
• Mid-prototype video: 30–90s walkthrough with on-screen annotations (use OBS or a short recorded reel).
• Polish comparison: Side-by-side images (v01 vs v03) with markup showing where geometry, cover, or sightlines changed.

Prefer annotated images (arrows, X/Y markers, distances) over raw screenshots. For annotated layouts and fast portfolio-ready image layouts, hybrid photo and cloud workflows are helpful—see hybrid photo workflows that include edge caching and creator-first storage tips.

4. Write concise version notes like commits

Every saved version should have a short note (2–6 lines) covering:

• What changed
• Why you changed it (goal or hypothesis)
• Result of the change or what you will test next

Example:

v03 — 2026-03-14
Reduced central corridor width by 30% to encourage flanking. Added side stair at B to create alternate high-ground approach. Hypothesis: reduce frontal firefights and increase flank engagements. Plan: run 6 controlled playtests and collect pathing telemetry.

5. Run focused playtests and summarize them like case studies

Playtests are the heart of proving iteration. Run small, repeatable tests with clear tasks. For each test create a one-page playtest report:

• Test Setup: map version, number of players, mode, duration
• Objective: what you measured (e.g., % of players using the central corridor)
• Data: pathing heatmaps, time-to-objective, death location distribution
• Observations: player quotes, confusion points, unexpected emergent behavior
• Decision: what you changed and why

Modern tips (2026): use inexpensive telemetry tools or Unity/Unreal event logs. Even basic CSV export of position samples can be converted into a heatmap to prove change — if you plan to scale telemetry or monetize insights later, see high-level guidance on architecting edge analytics and data strategies that apply to lightweight telemetry pipelines.

6. Annotate videos and make micro-reels

Short, edited videos are the fastest way to communicate iteration in interviews and online portfolios. Create:

• 30s before/after split showing the problem and the fix
• 60–90s dev-journal highlight that includes a quick voice-over or captions explaining decisions
• Long-form (4–8 min) deeper breakdown linked for reviewers who want more

Use simple mini-set techniques for social shorts — pairing a compact visual setup and a small bluetooth mic or lamp can lift production value quickly; see an example mini-set workflow at Audio + Visual: Building a Mini-Set for Social Shorts. For capture hardware recommendations, consult a hardware buyers guide for streamers and consider low-cost streaming device options for fast exports (low-cost streaming devices).

7. Keep a public or private dev journal

A dev journal is one of the most persuasive artifacts because it converts tacit knowledge into readable evidence. Entries don’t need to be long—3–5 paragraphs is enough. Include:

• Design intent and hypothesis
• Key changes and why
• Playtest takeaways and metrics
• Next steps

Tip: include a short screenshot gallery at the end of each entry with captions that point to the lessons learned. If you’re packaging dev-journals or downloadable PDFs, look at creative-brand examples such as how art books and catalogs boost creative brands.

8. Use data but tell a story

Telemetry is powerful, but raw charts can be opaque. Translate data into decisions:

• Show a heatmap with a short caption: “Players avoided the west flank due to a blind corner—added lighting and a ramp to encourage entry.”
• Use delta metrics: “Frontal firefight percentage dropped from 48% to 22% after corridor narrowing.”
• Combine qualitative quotes from playtesters with figures—this strengthens causality.

If you think about selling aggregated insights or creating a paid dataset later, review principles in architecting a paid-data marketplace to avoid common pitfalls around security and audit trails.

9. Organize your portfolio page for fast scanning

Reviewers spend limited time. Structure each map case as a card or section that contains:

1. One-line summary (design brief)
2. Key artifacts (blockout + mid + final images)
3. One 30–90s reel
4. Playtest findings (one paragraph + 1 heatmap)
5. Downloadable dev journal or PDF (for deeper review)

Lead with the one-line summary and the 30s reel—those two elements determine whether the reviewer clicks to read more. Consider domain strategies if you plan to host multiple case studies or microsites—see guidance on domain portability for micro-sites and portfolio portability ideas.

Practical templates you can copy today

Below are ready-to-use templates for assets to include in your portfolio.

Version note template (2–6 lines)

v{n} — YYYY-MM-DD — MapName
What changed: [short list]
Why: [hypothesis/goal]
Next: [planned tests or changes]

Playtest report template (one page)

• Map / Version: MapName_v{n}
• Setup: Mode, players, duration
• Metrics: Heatmap image, % time in chokepoint, avg time-to-objective
• Top 3 observations: short bullets
• Decisions: what changed next

Dev-journal entry (sample)

2026-02-18 — StellaPrototype_v02
Goal: Reduce dead-end loops and improve sightline predictability for small-squad play.
Change: Replaced maze-like corridor on level 2 with a short oval route; added mid-height cover and a visual landmark near the objective.
Playtest: 8 players, 3 rounds — heatmaps show decrease in lost-player stops from 17% to 4%. Players reported “easier navigation” and used alternate route 28% of the time. Next: shift cover density and test again.

Privacy, credits, and ethics

If your playtests use real players, get consent to share clips. Anonymize player names and avoid posting voice recordings without permission. Always credit collaborators and tools (third-party assets, mods) in a small visible footer—this level of transparency signals professionalism. For privacy checklists when using AI tools and transcripts, consult privacy best practices at Protecting Client Privacy When Using AI Tools, and for legal hygiene around selling or licensing creative work to marketplaces see the ethical & legal playbook.

Tools and workflows popular in 2025–2026

• Version control: Perforce (teams), Git LFS (indies)
• Recording: OBS Studio for full captures; NVIDIA/AMD Recorder for GPU-accelerated captures
• Annotation & layout: Figma or Affinity for annotated images; Miro for flow diagrams
• Telemetry: Lightweight custom event logs + simple Python scripts or Tableau/Looker for heatmaps
• Portfolio hosting: Webflow, Squarespace, or a custom static site with embedded Vimeo/YouTube reels
• AI tools: Use AI-assisted transcription to convert playtest voice notes into searchable text; use image-upscalers sparingly to improve readability of screenshots (always mark AI edits)

Formatting and presentational tips

• Lead with a 30s show-not-tell reel
• Use bold captions for lessons—each artifact should answer “what I learned”
• Limit long-form pages to 2–3 maps per page for focused review
• Provide a downloadable PDF with your dev journal and raw data links for reviewers who want to dig deeper

Common mistakes and how to avoid them

• Only final screenshots: Add at least two earlier versions with notes.
• No measurable goals: Add a brief design brief with at least one metric you tracked.
• Too much raw data: Summarize key insights—put the raw CSV behind a download link.
• No playtest context: Always include test setup (players, mode, tasks).

Applying this to an Arc Raiders-style map

Imagine you designed a mid-sized Arc Raiders map inspired by the new 2026 roadmap. Use the following micro-plan:

1. Write a 1-line brief: “6–10 min co-op map that rewards verticality and split-team tactics.”
2. Create blockout and capture two orthographic shots plus player POV.
3. Run closed playtests (6–8 players) and capture heatmaps of player flow.
4. Annotate the central objective area and create a before/after reel showing how you fixed a dominant frontal choke.
5. Write a dev-journal entry connecting a metric change (e.g., flank usage +40%) to the design change that caused it.

Framing your work like this echoes how Embark iterates maps in production: keep older versions, measure, and deliberately try variants across size and scope.

Actionable checklist (start today)

• Create a one-line brief for one map and save it as a project root file.
• Capture and export three versions: blockout, mid, final—name them consistently.
• Run one 6-player playtest and generate a heatmap.
• Write a 150–300 word dev-journal entry and pair it with a 30s reel.
• Publish the case as a single card on your portfolio with a downloadable PDF dev-journal.

Final takeaways

In 2026, the most competitive game portfolios do one thing extremely well: they show iteration. Use consistent versioning, pair visual artifacts with analytics and short playtest narratives, and structure each map as a mini case study. Treat every screenshot as data and every reel as a hypothesis test.
