 - Frontmatter is one `key: value` per line; lists are `[a, b]` or indented `- item` lines. A key given twice is an error. Entry files may not contain emoji.
 - `grid_dimensions` / `camera_perspective` / `hardware_tags`: optional metadata for 2D and UI entries. `3d` and `characters` entries leave `camera_perspective` out: it describes a 2D camera, and those entries have none.
 - `maintenance`: optional, `archived` | `inactive` (V22). Set `archived` when the source repository is archived, and `inactive` when it has had no push for over three years, with a dated `- Maintenance:` line in Notes saying what you read. Leave it out otherwise. The weekly link check reports a GitHub source whose state no longer matches.
+- `engine_lock`: optional, `unreal` (V23). Set it only when the licence restricts use to products built with that engine, as Epic's "UE-Only Content" listings do, and quote that line in Evidence. The site shows a **UE only** badge. Leave it out for content that is merely *made for* an engine.
+- `ue_versions`: optional, the Unreal Engine versions the source itself states, as `5.4`, `5.4-5.8` or `5.4+` (V23). Say in Notes where the range came from (README, `.uplugin`, release names, listing). Never infer it.
+- Unreal plugins use `subcategories: [unreal, ...]` and `formats: [unreal-plugin]`; Unreal projects and content packs use `formats: [Unreal]`. The validator rejects a GPL or LGPL licence on either, because the Unreal Engine EULA forbids combining the engine with that code (see [`docs/unreal.md`](docs/unreal.md)).
 - `url`: an `https://` address (`http://` only where the source has no https). Other schemes are rejected.
 - `verified`: ISO date (`YYYY-MM-DD`) of your last license check. It must be a real date, no later than tomorrow in UTC, and no newer than the newest date in `## Evidence` (V8): a new `verified` date needs a new dated Evidence line from the same check. Dates inside URLs do not count as Evidence dates.
 - `status`: `active` | `needs-review` | `deprecated`. A `deprecated` entry needs a `- Deprecated:` line in its body giving the reason (V9). `active` means the licence, the commercial stance and the credit requirement are all settled: an `unknown` in `license`, `commercial` or `attribution_required` keeps an entry at `needs-review`. The validator enforces this (V14), and rejects `formats`, `subcategories` or `tags` values that differ only by case, punctuation or a trailing "s" from one already in use (V13).

+# Cropout Sample Project
+
+Epic's free top-down casual RTS sample: a family-friendly farming and village game built to show cross-platform best practice from low-spec mobile up to consoles and PC. It demonstrates Common UI, Enhanced Input and Geometry Script, and is built in Blueprints. Delivered as an Unreal project through Fab and marked UE-only.
+
+## Notes
+
+- Contents: Blueprints, materials, VFX, stylized characters, buildings and procedural island generation for a small resource-gathering RTS
+- UE versions: the Fab listing's "Unreal Engine versions" field read 5.2 – 5.8 on 2026-10-13 (first published June 2023, last update September 22, 2026)
+- Licence: Fab Standard License, free on both tiers, and the description states "UE-Only Content - Licensed for Use Only with Unreal Engine-based Products", hence `engine_lock: unreal`. The stylized art cannot be exported to other engines
+- Redistribution: this is Epic content and may not be redistributed in source form or committed to a public repository. Epic's content licence says you "may not Distribute Licensed Content in source format to third parties except to employees, affiliates, and contractors who are utilizing the Licensed Content in good faith to develop a Project on your behalf"
+- Gotchas: the project is pure Blueprint, which makes it approachable but means logic changes are graph edits rather than code diffs; touch and gamepad input paths both exist, so test both after edits. Epic's landing page is unrealengine.com/cropout

+# Fab Free Listings and Limited-Time Free
+
+Fab, Epic's asset marketplace, has two kinds of free content. Permanently free listings are found with the search page's Free filter and come from Epic, Quixel and third-party sellers. The Limited-Time Free program makes a few normally paid products free for two weeks, with a new set every two weeks; the current set is on the [Limited-Time Free](https://www.fab.com/limited-time-free) page. This entry points at both; individual giveaway items are not catalogued here because they change every fortnight.
+
+## Notes
+
+- Licence varies per listing: most carry the Fab Standard License, some carry CC-BY (credit required), and some Epic and Unreal-specific listings add a "UE-Only Content" line that restricts them to Unreal Engine. Read the Details panel and description of each listing before you rely on it
+- Standard License listings: commercial use allowed, no credit required, not limited to Unreal unless the listing says UE-Only
+- No redistribution for Standard License listings: the Fab EULA summary says you may not "Resell or redistribute the asset for free on a standalone basis or allow others to do the same". Do not commit Fab downloads in source form to a public repository
+- Limited-Time Free items must be claimed inside the two-week window; the free price ends on the stated date (for example "Until October 20 at 9:59 AM ET" on 2026-10-13)
+- Many free listings are Unreal-only by format even when the licence is not, because they ship as Unreal projects or asset packs
+- Epic's own free packs are catalogued separately: [megascans-starter-content](megascans-starter-content.md), [electric-dreams-environment](../environment/electric-dreams-environment.md), [paragon-characters](../characters/paragon-characters.md)
+
+## Evidence
+
+- Live Epic forum announcement [Fab Limited-Time Free Content](https://forums.unrealengine.com/t/fab-limited-time-free-content/2738884) (2026-10-13): "We’re partnering with Fab creators to offer select content free for a limited time on Fab. We will be releasing new free content every two weeks. Limited-Time Free products will only be free for two weeks"
+- Live [Limited-Time Free on Fab](https://www.fab.com/limited-time-free) (2026-10-13): "Limited-Time Free (Until October 20 at 9:59 AM ET)", listing three products from third-party sellers
+- Live [Fab search, Free filter](https://www.fab.com/search?is_free=1) (2026-10-13): results mix third-party listings shown as "-100% Free*" and Quixel Megascans listings shown as "From Free"
+- Live [Fab EULA](https://www.fab.com/eula) (2026-10-13): Standard License "Use the assets commercially or privately"; "You may not: Resell or redistribute the asset for free on a standalone basis or allow others to do the same"; "You are not required to give credit to the publisher you acquired the Fab asset from"; "CC-BY (Creative Commons Attribution License) The usage is governed by the terms of the Creative Commons license."
