# F.E.A.R. 360 Recompiled

The Xbox 360 F.E.A.R., running natively on PC. 4K, evenly paced high frame rates, a controller in your hands.

> Unofficial. **No game data included.** Bring your own Xbox 360 disc.

## Why

The 360 version came out about a year after the PC original and is the more complete one: **Instant Action** mode, a dual-wieldable machine pistol and an extra bonus level that the PC never got. It has been stuck on the console ever since, at 720p and 30 fps. The plan is to free it, then add *F.E.A.R. Files* (Extraction Point + Perseus Mandate, 360) so the whole F.E.A.R. 1 package lives in one place.

## What it is

A **static recompilation**: the game's PowerPC code is translated to native x86-64 C++ ahead of time ([ReXGlue](https://github.com/rexglue/rexglue-sdk)), and a game-specific runtime stands in for the Xbox. It is not an emulator and not a decompilation.

- **CPU:** the 360's `default.xex`, recompiled. All game logic, AI and physics are the console's own.
- **GPU:** [fear-nx](https://github.com/infriker/fear-nx)'s Vulkan Xenos renderer, which fixed the menu and video corruption the stock ReXGlue renderer has with this game, plus our resolution scaling.
- **Your data:** the game files come from your own disc; nothing proprietary is in this repo.

## Status

| | |
|---|---|
| ✅ Boots, menus, intro videos, campaign, Instant Action | `port-nx` with `--nx_renderer native` |
| ✅ 4K: integer internal resolution scaling (3× = 3840×2160) | our patch to fear-nx's renderer |
| ✅ The game's own 2×/4× MSAA and 16× anisotropic filtering | on top of the scale |
| ✅ Frame pacing locked to the display: 80 fps on 240 Hz, every frame shown for exactly 3 refreshes ("Frame rate's feeling really good") | the game's vblank follows the display's real one (DXGI, any GPU vendor), each frame held to the fewest refreshes that keep it at or under 90 fps (72 on 144 Hz, 60 on 60 Hz); above ~90 the 360's tracer code breaks; `-FrameRate <n>` sets that limit ([PROGRESS](docs/PROGRESS.md#play-test-4-2026-10-22-display-locked-pacing)) |
| ✅ No white flash as a new area comes into view | textures still streaming in are waited for instead of drawn as the empty texture (to confirm hands-on) |
| ✅ Logic, gunplay, physics intact | 10-minute play-test |
| ✅ Impact smoke and bullet holes at 80 fps | the dust thins out as it should, and model animations run at exactly the time that passed (the engine dropped a fraction of a millisecond every frame); the big "rock" craters are the game's own bullet-hole decals, the same size at 30 fps; the haze hasn't come back (watching) ([PROGRESS](docs/PROGRESS.md#play-test-4-2026-10-22-display-locked-pacing)) |
| ✅ Chapter cards, intro text and credits drawn once and centred; no half frames at cuts | a clear the game does through an aliased surface now reaches the real one ([PROGRESS](docs/PROGRESS.md#two-tile-frames-doubled-cards-and-half-frames)) |
| ✅ Right stick without the 360's turn ramp (default) | "feels significantly better": the 360's stick tuning patched on the fly from your own data; `-LookRamp console` restores it ([PROGRESS](docs/PROGRESS.md#play-test-2-2026-10-22)) |
| ✅ Saving with any controller (to confirm at a checkpoint) | every controller drives player 1, the local profile that saves (a second XInput device used to make the pad player 2, who can't save) |
| ⏳ Movement may feel bouncier than PC | compare game-database tuning and 30 vs 120 fps |
| ✅ PC textures in place of the 360's low-res ones | a local pack built from your PC copy: **4,710 textures at 4× the pixels**, 81% of what the intro draws ([docs/TEXTURES.md](docs/TEXTURES.md)) |
| ✅ *PC Settings* and *Quit to Desktop* in the main menu | "looks awesome": two entries added to the game's own menu (under Options) open a settings panel (resolution, window, frame rate, texture filtering, PC textures, right stick, aim assist, animation timing; saved in your user folder) and a quit confirmation ([PROGRESS](docs/PROGRESS.md#main-menu-pc-settings-and-quit-to-desktop)) |
| ✅ One collection: F.E.A.R. and *F.E.A.R. Files* from one menu | "switcher works with controller and switch is fine between games": a menu before either game loads, *Switch Game* in both games' main menus, *PC Settings* and *Quit* in Files' too (`tools/launch.ps1 -Collection`) ([FILES](docs/FILES.md#the-collection-launcher-2026-10-22)) |
| ⏳ *F.E.A.R. Files* (Extraction Point + Perseus Mandate) | plays at 4K and 80 fps with its own PC texture pack (7,607 textures) and F.E.A.R.'s right-stick fix: "running really well… ran better out of the box than Fear 1 did"; next, the smoke plumes and an optimisation pass. The plan for one collection: [docs/FILES.md](docs/FILES.md) |
| ⏳ Linux | the renderer is Vulkan already; build untested |

## Build and run (Windows)

```powershell
pwsh -NoProfile -File tools/build-nx.ps1        # first time ~15 min: ReXGlue SDK from source + codegen + game
pwsh -NoProfile -File tools/launch.ps1 -Nx -Extra '--nx_renderer native'
```

Launcher defaults: fullscreen, `-Scale 3` (4K internal), `-FrameRate auto` (locked to your display's refresh, at most 90 fps), 16× AF. Options: `-Scale 1..3`, `-FrameRate auto|<20-240>` (the limit), `-Timer` (the old software vblank timer instead), `-Present auto|immediate|mailbox|fifo`, `-TexturePack <folder>`, `-LookRamp console|nodelay|instant|off`, `-NoSoftLock`, `-Windowed`, `-Extra '<more flags>'`.

**PC textures (optional, needs the PC version):** build a pack from your own PC install once (about 6 minutes, 1.3 GB, stays in the gitignored `private/`), then add `-TexturePack private/texture_pack`. Steps in [docs/TEXTURES.md](docs/TEXTURES.md#build-a-pack).

Put your own `default.xex` (title `565507D9`, SHA-256 `e7fccdf6…2792`) and `Game/` folder in `port/assets/` ([docs/RIPPING.md](docs/RIPPING.md); `python -I tools/xdvdfs.py <disc.iso> extract port/assets` unpacks an ISO). The SDK source recipe is in [docs/HANDOFF.md](docs/HANDOFF.md#how-it-is-built-and-run).

## Layout
