Linux port done in-house by Timothee Besset and the Mac port done by Aspyr Media. In 2003, the game was ported to the PlayStation 2 and Xbox video game consoles and subtitled as Operation Resurrection and Tides of War, respectively. Console version differences Both console versions include an additional single-player prequel mission, set in the fictional town of Ras El-Hadid in Egypt. The latter half of the level features an extensive underground burial site with many undead enemies, as does the original first mission. This prequel level is likely closer to the developers' true intentions for the story, as indicated by the distinctly Egyptian design of the burial site, including the presence of sand, traps, mummies and hieroglyphs on the walls in some areas (in the original storyline, this site is found in the middle of a German village during the second mission). By contrast, the single-player storyline in the Windows version starts at Castle Wolfenstein. The PS2 version has a bonus feature which allows players to purchase items at the end of each level by finding secrets. In the Xbox version a Secret Bonus is awarded after every level when all the secret areas for that level have been found. It also has several new equipable items and weapons as well as new enemies. The two-player co-op mode is exclusive to Xbox and allows the second player to play as Agent One, altering the game in which he was never killed and played out the missions to the end. This allows for the story to support that Agent One either survived. Xbox version also has downloadable content, system link play and had online multiplayer via Xbox Live before Live play was disabled for original Xbox games. A Platinum Hits edition of the game was also released for the Xbox. The PlayStation 2 version does not support online multiplayer. Completing the Xbox version unlocks a further bonus: the original Wolfenstein 3D. Source code release The source code for Return to Castle Wolfenstein and Enemy Territory was released under the GNU General Public License v3.0 or later on August 12, 2010. The ioquake3 developers at icculus.org announced the start of respective engine projects soon after. Community mods On 15 October 2020 a community overhaul mod RealRTCW was released on Steam as a free modification for original game. It features new renderer, expanded arsenal, rebalanced gunplay, new high-quality models, textures and sounds.
