Two "Fallout 3" versions were almost released years ago. Those titles, however, got cancelled and one eventually became another game.

"Fallout 3" was released in 2008 and was followed by two RPGs, "Fallout: New Vegas" and "Fallout 4." Feargus Urquhart, the CEO of Obsidian Entertainment, revealed during an interview with IGN that there were two unreleased versions being developed years ago, a time when Interplay and Black Isle Studios were still the publisher and developer behind the "Fallout" game franchise.

One of those was a project codenamed "Van Buren" (which the public is highly aware of) and the other was a version that later became "Icewind Dale." The team was pursuing a 3D engine called NDL for the other project back then, a departure from the previous titles' 2D capability.

Unfortunately, Interplay encountered financial issues and the project became Black Isle Studios' role-playing game "Icewind Dale" instead, with the team working on it still intact. "Icewind Dale" takes place in icy tundra where players must fight frightening beasts and traverse through treacherous mountainsides and glaciers.

Urquhart also revealed that the 3D technology NDL was later bought by Gamebryo. The latter then used the engine to power "Fallout 3" after the franchise was acquired by Bethesda.

In other news, "Fallout 4" is getting a huge visual update next week and it will make the game's tiniest details more pronounced. The High-Resolution Texture Pack, however, doesn't come without a price.

According to Bethesda, the PC update requires no less than a 2015 desktop Core i7 chip, 8 GB of RAM and an additional 58 GB of storage for the new visual art. The system should also be equipped with either a GeForce GTX 1080 or the AMD Radeon RX 490, which is still unreleased as of this moment. The PC should run using a 64-bit Windows 7/8/10.

Players who prefer playing the game on a console can also enjoy the upcoming update. It will be available at 1440p resolution for the 4K set for Sony's PlayStation 4 Pro. That will provide a bigger draw distance for objects, trees, grass and NPC. There's better "godray" lighting effects, too. Check out the High-Resolution Texture Pack upgrade in action below.
