Underworld Adventures for MorphOS
=================================

Underworld Adventures is an open-source recreation of the engine behind
Ultima Underworld: The Stygian Abyss (Blue Sky Productions / Origin, 1992).
It reads the files of the original game and plays them in 3D with OpenGL.

The engine was unfinished. For this port the game rules were written anew:
doors, combat, creatures, magic, inventory, conversations and the main plot.

This version plays Ultima Underworld 1 only, not Ultima Underworld 2.

THIS ARCHIVE CONTAINS NO GAME DATA. You supply it yourself, see below.


SUPPLYING THE GAME DATA
-----------------------
Copy the files of the PC version into the uw1 drawer, whole: everything that
sits next to UW.EXE (CRIT, CUTS, DATA, SOUND). The GOG release and an original
install both work.


HOW TO RUN IT
-------------
Copy the UWAdv drawer on a writable volume and double-click the UWAdv icon.
Screen resolution and fullscreen are set in uwadv.cfg.


GOOD TO KNOW
------------
- Trading has no window: the objects shown to a character are chosen for you.
An object held on the mouse pointer is offered first.
- There is no MIDI music on MorphOS: only a few tracks play.


DRAWER CONTENTS

CHANGELOG
---------
1.1 - the character you create is kept (it was replaced by default values)
- much less getting stuck against doors
- no more crash when using a key twice
- first kill no longer jumps to level 16
- portcullises are drawn with bars, not as a stone wall
- holding a combat key now charges the attack
- the panel chain and F7 work
- Return in the main menu with nothing selected: no more black screen
- a new game starts with an empty inventory
- an object held on the pointer stays visible after loading a game
- "You have died" stays on screen for 3 seconds
1.0 - first public release
