Free ultima software for linux

XU4 is a remake of the computer game Ultima IV. The goal is to make it easy and convenient to play this classic on modern operating systems.

XU4 is primarily inspired by the much more ambitious project Exult. Linux is the primary development platform but it gets ported to Windows and MacOS X regularly. It should be trivial to port to any system with SDL support.

XU4 isnt a new game based on the Ultima IV story it is a faithful recreation of the old game, right up to the crappy graphics.

If you are looking for a game with modern gameplay and graphics, this is not it yet. New features that improve the gameplay and keep with the spirit of the original game will be added.

XU4 also tries to maintain strict compatibility with the original for its savegame files. You can use a game saved in XU4 with the original and vice versa, at least in theory.

TileLib is meant to be an easy to use graphics library geared towards people wanting to make tile based games. Such as RPGs, side scrollers, etc. It is meant for people developing with the Allegro graphics lib. What I eventually envision is to make TileLib be a very versatile core library for making tile based games.
Im going to pack as much useful stuff in here that should belong in the basic tile based games library. This means, Im not going to add support for controlling players, just support for loading worlds/scrolling them/interacting with them/etc. Maybe later Ill work on something like that. For now, the feature set is limited but still useful. See the next few sections for more information.
Main features:
- Smooth scrolling
- Support for 4 map layers (base, fringe, object, and roof)
- Ability to place tiles at offsets other than (0,0), i.e. can center tiles.
- Support for disappearing roof tiles ala Ultima style games/old RPGs
- Unlimited map size, limited only by amount of RAM on target system
- Built in functions to scroll the world
- Functions to retrieve information on tiles in the world
- Functions to modify information on the tiles in the world
- Easy to use
- Ability to limit the map window, as in create a border of any size to place it in. Useful for having other windows, like a status window.
- Support for any video mode via Allegro
Enhancements:
- Added smooth scrolling support
- Fixed minor bug in tilelib.h that was lacking some #ifndef tags
- Added 4th example program, TLtest4, to demonstrate smooth scrolling
- New documentation page layout

Pentagram projects goal is to create an Ultima VIII engine.

Pentagram is a game engine for running Ultima VIII on modern operating systems. Since a modified version of the Ultima VIII engine also powered the two Crusader games (Crusader: No Remorse and Crusader: No Regret) the teams ultimate goal is to be able to run those two as well.

For those not familiar with the game: you are playing the role of the Avatar who already several times saved the worlds from evil forces in Ultima I-VII, but now you are thrown into the unknown world, which is already destroyed by those forces and you should explore it and find out the way to defeat the evil yet another time.

On your way you will find many friends and foes including undead creatures, giant spiders and trolls, talk to local people and solve many mysteries and puzzles.

Labyrinth of Worlds project is an Ultima Underworld II rewrite.
LoW is a rewrite of the first-person role-playing game Ultima Underworld II: Labyrinth of Worlds that came out in the early 1990s. One of the most celebrated game of its genre, this rewrite attempts to recapture the minutiae and spirit of the original.
At the moment, the tech demo allows you to walk (and jump) around all the Underworld II levels and worlds, has all NPCs and most monsters. You also get to see and manipulate all the dynamic objects of the game, and peek inside containers. The paperdoll has been implemented, too, and lets you access your inventory as well as wear/wield armor and weapons.
It is now possible to converse with the various NPCs. While not all the conversations work correctly (or at all) most do for the most part and it is now possible to actually understand the storyline. :) NPCs are also able to give items, now.
Another worthy project you might want to go take a look at is Underworld Adventures which seeks to recreate the first installement of that series and is doing a darn good job of it.
If you are an Ultima VII fan, then Exult is going to tickle you pink! The freshly released version 1.0 will allow you to play Black Gate and Serpent Isle with the addons on modern architectures, with a few gameplay improvements to boot!
Enhancements:
- Fixed executables
- new gameplay features, including wearable items
- improved user interface
- performance improvements
- more complete conversation support (including being given items),
- working keys and locks

SunUO is a free Ultima Online server for Linux/Mono and Windows.NET, based on RunUO. Ultima Online is a commercial MMORPG by Origin / Electronic Arts.
I created this fork of RunUO because I wanted to improve it, but the RunUO team refused to talk to me.
SunUO is designed to be a drop-in replacement for RunUO. No manual changes are required to port an existing RunUO 1.0.0 shard to SunUO.
Main features:
- SunUO is more stable than RunUO (exception handlers); a buggy script does not crash the server
- SunUO runs on Mono 1.1 (Linux, FreeBSD, ...) out of the box
- SunUO makes script compilation optional; a fresh install starts in about 3 seconds, including world load
- SunUO supports multiple script libraries; this helps keeping tidiness
- SunUO introduces a configuration file; having to edit source code to configure a shard sucks (ever upgraded to a new RunUO version? Then you know what I mean)
- SunUO is not vulnerable to the directory entry order faction bug, which may break all faction memberships and town ownerships in some cases. The RunUO team refuses to accept this as a bug, stating that .NET automatically sorts directory entries (which is plain wrong).
Enhancements:
- This release supports UO client version 6.
