Portal: Prelude: Difference between revisions

*International: October 9, 2009

'''''Portal: Prelude''''' is an unofficial prequel to the game [[Portal]], developed by an independant team of three. The game features a brand new storyline focussing on the pre-[[GLaDOS]] era of [[Aperture Science]] where test subjects are monitored by employees of the facility. The game spans across 8 chapters covering 19 [[Test Chamber|test chamber]]s which follow a gradual learning curve similar to that of Portal. In addition, 48 [[Test Chamber#Challenge Chambers|challenge maps]] and 8 [[Test Chamber#Advanced Chambers|advanced]] test chambers are included with the mod.

Many gameplay elements from Portal make a return in ''Prelude'', while entirely new gameplay devices were created exclusively for the mod, such as localised graviational fields. Portal: Prelude also features over 400 lines of voice acting, with English, French and German subtitles.
