Brave Arms is an action game that was in early development stages at Namco’s Project Aces team, planned for the Playstation 3. We dont know how much work went into the game, as the only documents about it’s existence are a couple of scans (?) that shown some target renders and concept arts, probably created to pitch the project. As far as we can get from the japanese translation (@ Wikipedia), Brave Arms took place in Gran Rugido, the capital of the Kingdom of Sapin, an allegory of Spain in the Ace Combat series. The player would had fight alongside the local resistance against an unknown military regime.
There are no more info on Brave Arms and it’s currently unknown why it was never finished.
Fallout: New Vegas is an action FPS/RPG developed by Obsidian Entertainment and published by Bethesda for the Xbox 360, PlayStation 3, and PC. Before the game was released changes were made to the game near the end of development. Most of what is documented below can be found in promotional screenshots, videos, and developer diaries.
During initial development, Fallout 3 super mutants appeared in the game as placeholders. Possibly until the New Vegas super mutant variant was created. For example; Neil – a friendly super mutant you meet at Black Mountain – originally appeared as a Fallout 3 super mutant in the beta. You can compare what Neil looked like in the beta to what he looks like in the final below this paragraph.
Another character that was changed in New Vegas is Mr. House. Mr. House uses a master computer to communicate to the player in the Lucky 38 casino. At the time, Mr. House appeared different on the computer screen in the video: developer diary #4 – factions.
WarDevil: Enigma (aka WarDevil: Unleash The Beast Within) is a cancelled action game that was in development for the Xbox 360 and Playstation 3, from 2004 to 2010 by Digi-Guys (Ignition London), a subsidiary of Ignition Entertainment. The studio started to work on this project as a tech demo for the “Xbox 2” console, but after almost 6 years and a lot of money spent, they were closed down, 30 staff have been laid off and WarDevil was officially canned. It seems that apart from the awesome graphic engine, there was not much in a playable state.
Digi-Guys created an early prototype of the game on the original Xbox, as we can read in an article by Edge:
Some more about that Xbox demo, first, as it casts Whitehurst’s rhetoric in a substantially different light. It was developed in 2005, when you’d expect all eyes to be on Xbox 360. Such is the nature of Digi-Guys’ new pipeline, though – designed as it is to render Hollywood-grade visuals at true 1080p, at an unbroken 60 frames per second, using just one core of a modern console CPU – that the demo would have to do much more with much less to be a valid proof of concept. […]
The background for this one is a visit by Sony reps in October 2005, by which time Whitehurst had built the kind of HD studio that was still having to be described to most developers. They saw the Xbox demo – and remember, this is the same year that Doom 3 struggled its way on to the same console – and were suitably impressed. “They said: ‘Here’s some devkits. Let’s see what you can do’. So we got a very quick build running, then there was this whole shebang for the E3 2006 [PS3] launch, with everyone having to submit what they were doing.” […]
The demo is essentially a short section of gameplay and introductory cutscene in which the WarDevil, an ‘ultimate killing machine that can make 10,000 men lay down their arms’, shows his stuff against the troops of his nemesis, The General, using a God Of War-style mix of blade attacks, martial arts and supernatural powers.[…]
Valkyria Chronicles (aka Battlefield Valkyria: Gallian Chronicles in Japan) is a tactical j-rpg developed by SEGA and released for Playstation 3 in 2008. In the screens below,we can see a beta version of the map and of the HUD.
Developed by Evolution Studios for the Playstation 3, Urban Smash was going to be an original IP driving game set in real-life locations, but was put on hold during development of MotorStorm Pacific Rift. As revealed during a developer session at the Eurogamer Expo 2010 however, the project later evolved into MotorStorm Apocalypse and a prototype video that was shown during the presentation can be found below. You can read a preview of Apocalypse with more info about the final game at Gamer Limit.
