Alpha 8.5 — Alien Force Aliens & Ten Languages

• Alien Force aliens: Chromastone, Jetray and Goop on All Aliens page 4, with their own attacks, effects, R3 ring pictures and holograms. Jetray glides and double jumps; Goop double jumps. In the launcher, Setup → Import Alien Force aliens builds them from your own extracted Ben 10 Alien Force: Vilgax Attacks Xbox 360 folder, as the Four Arms import does.
• Ten languages: English, Arabic, German, French, Spanish, Italian, Portuguese, Turkish, Russian and Japanese, in the launcher (Saves & Languages) and in the game (Options → Video → Language), shared and changed live. Menus, HUD, tips and dialogue follow the language, including Arabic, Russian and Japanese through a new overlay, and Enhanced Cinematics subtitles. Translations ship with the game; nothing extra to download.
• Ultimate balance: Ultimate light hits deal 0.35 (normal aliens 0.2) and special abilities 1.75, so they no longer one-shot ordinary enemies. Each Ultimate ability spends 4, 6, 8 or 10 seconds of Ultimate time, and four Ultimatrix prongs show on the HUD while an Ultimate is active.
• Field of View: −20° to +30° for gameplay, under Options → Gameplay or in the launcher. The music overlay shows song titles in any script.
• Fix: landing a Big Chill glide no longer crashes.

Known issues: Chromastone shows a graphical glitch in The Catacombs. Portuguese and Turkish game text is not translated yet, and the Arabic, Russian and Japanese text is not professionally reviewed.

Building: after code generation run tools/apply_game_integration.py, tools/apply_text_overlay.py and tools/apply_form_effects.py. Back up native-rex/generated/default before editing ben10_manifest.toml, because the build regenerates it.

Alpha 8.2 — Mouse Menus, Music Integration & Modern Button Icons

• Mouse in menus: an Omnitrix cursor replaces the Windows pointer in menus and turns red in Play as Albedo mode. Hover and click work in the stock menus, the pause menu, the Options pages, Level Select and the Upgrades wheel. The R3 form wheel supports hover.
• Keyboard and Mouse: the "Keyboard" button icon option is renamed "Keyboard and Mouse". Prompts show keycap and mouse images for your current bindings. The Controls page now has one custom profile, with Restore defaults.
• PC mouse camera: the camera turns with mouse movement like a PC game, independent of frame rate, with adjustable sensitivity and no speed cap.
• Smart Music Integration: detects Spotify and other players through Windows media controls. Press M or View / Share during gameplay to open the music overlay. It shows title, artist, album art and progress, with Previous (LB / L1 / Q), Play-Pause (X / Square / Space), Next (RB / R1 / E) and Close (View / Share / M). The game keeps running while it is open, and its input does not reach the game.
• Audio ducking: while music plays, the game audio fades down smoothly and fades back after the music stops. Set the amount with Music priority in the music overlay (0% = off). Windows and Spotify volumes are never changed.
• Sound settings: the in-game Sound page adds Music Integration. The launcher has a new Sound tab with Music, SFX and Voice volume and Music Integration.
• Modern button icons: new Xbox and PlayStation face, bumper, trigger and stick icons in the stock menus, HUD prompts, QTEs and text prompts. Auto follows the connected controller.
• Options badge: the Options pages show the original Omnitrix badge again. The launcher extracts it from your game files, with a red version for Albedo mode.

Known issues: Ultrawide is not supported.

For an Alpha 8.2 build, compile both launcher bridges with --hero-time --gpu-diagnostics --performance-alpha5 --ultimate-voices --discord-presence, adding --four-arms for the optional bridge. Install the SDK with the updated sdk-patches/rex-sdk-local.diff. The button icon resources are generated by tools/build_modern_button_icons.cs and tools/build_keyboard_prompt_sprites.cs.

Alpha 8.1

• Play as Albedo: Both Way Big appearances swap live when you resume the final fight. Ben fires green and Evil Way Big fires red, whichever side you play.
• Final boss HUD: Restored the sharper Ben Way Big portrait with the Potis Altiare badge. The health bar stays yellow.
• Fixes: Restored the Alpha 8 graphics profile, fixed final-fight pause behavior and button prompts, and improved cinematic ZIP subtitle matching.

For an Alpha 8.1 build, compile both launcher bridges with --hero-time --gpu-diagnostics --performance-alpha5 --ultimate-voices --discord-presence. Add --four-arms for the optional bridge. Stage tools/way_big_portrait.rgb beside prepare_albedo_textures.py in the importer.

Alpha 8 — Reworked Options, 120 FPS & Enhanced Cinematics

• In-game Options: redesigned the Options hub and the Gameplay, Sound, and Video pages. Gameplay groups the standard and extras settings on one page. Video combines display, button icons, and graphics. Credits are available from the main-menu Options hub.
• Video and performance: added a 120 FPS frame-limit option and individual controls for internal resolution, anti-aliasing, texture filtering, sharpening, and screen bloom.
• Launcher: added Gameplay settings shared with the game, separate artwork for Home and Settings, and installed-content checks for Four Arms and the enhanced cinematic pack.
• Enhanced Cinematics: optional in-game playback of 19 clips in 1080p/60 FPS MP4, with subtitle tracks, keyboard/controller skip, and volume linked to the game's Windows Volume Mixer setting. Enable it under Launcher Settings → Video after importing the ZIP. Turn it off to use the original cinematics. Download the Enhanced Cinematics ZIP.
• Menu fixes: improved Albedo theme colors and pause-menu row spacing, and restored the main-menu Ultimatrix backdrop after using Cheats.

Known issues: 120 FPS depends on the scene and hardware, with drops reported in The Amazon. The crank prompt above Humungousaur can still show the Xbox icon under PlayStation or Keyboard. A gameplay crash is still under investigation.

Alpha 7.1 - Button Icons, Albedo Fix & Game Icon

• Launcher and startup: redesigned launcher and settings screens, an optional Skip Intro setting, and a fixed Quit to Launcher action in the pause menu.
• Ultimate Omnitrix: restored the red and yellow HUD accents during Ultimate transformations.
• Performance: carries forward the Alpha 5 frame pacing fix, tested locally at 30 and 60 FPS.

Alpha 6 - Ultimate Voices & Discord Rich Presence

Community Alpha 6: Download the installer and read the release notes.

• Ultimate voice lines: restored the Hero Time name callouts for all five Ultimates using their original recordings.

Alpha 5 - Performance & Installer

• Performance: fixed a CPU-side slowdown that dropped a heavy area to about 15 FPS. It now holds 30 FPS, and 60 FPS where the hardware allows.
• Single installer: one EXE with the launcher, native runtime and dependencies. It contains no game files; you prepare the game from your own ISO.

Keyboard and controllers

Controllers are supported natively through the SDK SDL backend, including XInput-compatible controllers. Button icons can be set to Xbox, PlayStation, Keyboard and Mouse, or Auto under Options → Video. Contextual actions follow the original game.

Keyboard	Xbox input / purpose
WASD	Left stick: movement
Arrows	Right stick: camera
Space or semicolon	A: confirm / jump
Backspace or apostrophe	B: back / original B action
L / P	X / Y
Q or I	LT: alien wheel
E or O	RT: abilities; next wheel page while LT held with All Aliens ON

With All Aliens ON, hold Q and tap E to cycle pages. The mouse turns the camera during gameplay and points and clicks in menus. Rebind keys under Options → Gameplay → Customize Keyboard and Mouse Controls or in the launcher. Mappings checked against the SDK keyboard driver and launcher configuration; not every contextual keyboard action has been playtested.
