“Freedoom”的意思、由来-开放百科全书

Freedoom is a project aiming to create open content for the free and open source software Doom engine. The project distributes three IWAD files: the two single-player campaigns named Freedoom: Phase 1 and Freedoom: Phase 2, and FreeDM, which contains a collection of deathmatch levels.

The project presents itself as complementary to the free and open source code of the Doom engine released by id Software in 1997 under the GNU GPL license. The content is licensed under the permissive 3-clause BSD license. It allows custom levels and other customizations designed for Doom, Doom II or Final Doom (e.g. PWAD files) to be used with Freedoom.

Features

It is distributed as IWAD files (game data) only without a game engine. The player must provide a Doom source port which are unofficial ports of the Doom engine. The website recommends using GZDoom and/or Crispy Doom. In the past,{{When|date=August 2017}} Freedoom required a limit-removing engine with Boom extensions and would not work with the original Doom engine's source release properly, due to the static limits of the original Doom engine and lack of Boom extensions. Currently (for the 0.11.1 version), support for Boom extensions is no longer imperative and Freedoom should run on any limit-removing engine. The future 1.0 version of Freedoom is expected to be fully compatible, except for the savegame buffer overflows for certain levels,^[4] with the original Doom engine, also known unofficially as Vanilla Doom, and, consequently, with certain conservative fan-made ports, such as Chocolate Doom.^[5]

Gameplay

The gameplay mechanics (monster and weapon behavior, etc.) are identical to the original Doom games, but with completely original artwork and level design.

Freedoom: Phase 1

This IWAD contains levels arranged into four episodes, similar to the original Ultimate Doom. This allows mods for the original game to be played.

Freedoom: Phase 2

This IWAD contains levels in a flat linear progression, similar to Doom 2. This allows mods for Doom 2 and Final Doom, which consists of two standalone megawads: TNT: Evilution and The Plutonia Experiment, to be played.

FreeDM

This IWAD, compatible with the original Doom engine, is a collection of original deathmatch levels, using the same artwork as the main Freedoom IWADs. Also, this one can be used to play mods for Doom 2 and Final Doom.

Similar projects

The project has also inspired other similar projects, such as Blasphemer for Heretic,^[6] and Zauberer, for Hexen.^[7]
