GitHub - freealbion/freealbion: A remake of the classic BlueByte RPG Albion.

What’s included so far:

most of the 2D and 3D map rendering (event based animations are missing; also no event based tile exchange)
walking 2D and 3D NPCs (random and along a given path)
basic player movement and collision detection (needs more reverse engineering though)
3D graphic enhancements: real dynamic lighting for each light source/object, hqnx graphics (up to 4x), anti-aliasing and mip-mapping
clock and compass
rudimentary event handling (map changes)
day/night cycle on 3D maps
cross-platform ;)

What’s not included and Known Issues:

Requirements:

OpenGL 3.2 Core and OpenCL 1.0/1.1 capable graphics card and drivers (i.e. GeForce 8+ or Radeon HD4+)
Windows: NT 5.1+, OS X: 10.7, Linux: any that is capable of the above
2 GB RAM are recommended (it can use up to 1 GB of RAM when generating the HQ4X textures)
256 MB VRAM minimum (only use 1X or HQ2X scaling, don’t use SSAA)
512 MB VRAM are recommended (can use HQ4X, but 1 GB+ is recommended when you want to use HQ4X and 1080p+ SSAA)
Albion v1.38 CD XLD files and main.exe
Mouse and Keyboard (no, there’s no touch version, yet)

How to get it:

Windows and OS X: http://albion2.org/dl/albion_pr1.zip
Linux: a binary distribution is rather difficult, so you’ll have to build it yourself

Build Instructions:

install/build a2elight (https://github.com/a2flo/a2elight/blob/master/README.textile)
on Windows/Linux: run “./premake.sh gcc” or “./premake.sh clang” and “make”
on OS X: open albion.xcodeproj and build it

Installation and General Advices:

on Windows/Linux: download and install the latest graphic card drivers (NVIDIA: http://www.geforce.com/Drivers, AMD: http://support.amd.com/us/gpudownload/Pages/index.aspx)
copy your Albion CD XLD files and main.exe to “albion_pr1/data/xld” (for file/folder structure read the readme.txt in that folder)
edit “albion_pr1/data/config.xml” to your liking (open it in an appropriate editor, notepad is not of them!)
VSync should always be enabled (you’ll get weird behavior on 2D maps otherwise)
Fullscreen is recommended for best performance (also set your fullscreen resolution)
Loading and Start-up times are high when using HQ2X or HQ4X, don’t panic
AMD/ATI drivers are known to act weird (if you’re experiencing bad performance on your high-end card, try quitting and starting the game again)

Controls:

WASD or arrow keys for walking
ESC to quit the game
C to toggle collision detection
+/- to increase/decrease day time
in 3D: right click to toggle camera rotation using your mouse
in 3D: V to toggle between “free cam” (flying) and “normal cam” (pinned to the ground)
in 3D: R to reset the camera+player rotation and position
Q to toggle debug texture display (use in combination with keys 1 – 7)
