Portal: Prelude (2008) PC - Complete Walkthrough / Full Game Mod

Portal: Prelude is an unofficial prequel to the game Portal, developed by an independent team of three. The game features a brand new storyline focusing 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 chambers which follow a gradual learning curve similar to that of Portal. In addition, 16 challenge maps and 6 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 localized gravitational fields. Portal: Prelude also features over 400 lines of text to speech, with English, French and German subtitles. #Portal #Portal2 #prelude ‒‒‒‒‒‒‒ Portal (2008) PC Complete Walkthrough / Full Game Mod ✦ Subscribe ✦ • https://youtube.com/Khonziel?sub_conf... ✦ Find me here ✦ • https://linktr.ee/khonziel ‒‒‒‒‒‒‒ ⏱ Timestamps 0:00:00 - Test Chamber 00 0:01:57 - Test Chamber 01 - Get the Orange 0:03:40 - Test Chamber 02 - Climb the Pipe 0:04:49 - Test Chamber 03 - Get the Blue 0:05:55 - Test Chamber 04 - Cross the Gap 0:06:58 - Test Chamber 05 - High Expectations 0:08:10 - Test Chamber 06 - Low Expectations 0:09:03 - Test Chamber 07 - Disintegration 0:10:13 - Test Chamber 08 - In a Hurry 0:11:12 - Test Chamber 09 - Fly Little Girl, Fly! 0:12:13 - Test Chamber 10 - Upside Down 0:13:04 - Test Chamber 11 - Energy Orb 0:14:36 - Test Chamber 12 - Derivations 0:16:09 - Test Chamber 13 - Duplications 0:18:00 - Test Chamber 14 - Battlefield 0:20:51 - Test Chamber 15 - Mind Maze/Wargame 0:27:56 - Test Chamber 16 - Loopback 0:31:25 - Test Chamber 17 - Through the Walls 0:37:45 - Test Chamber 18 - Companion Cube Hell 0:40:57 - Test Chamber 19 - Think Outside the Rooms 0:50:27 - Party 0:52:44 - Exploring Aperture Science 0:58:23 - GLaDOS: Activation 1:01:23 - GLaDOS: Avoid the Traps 1:04:32 - GLaDOS: Find the Morality Core 1:08:46 - GLaDOS: Install the Morality Core 1:09:52 - Ending 1:11:14 - Credits 1:14:56 - Post-Credits Scene
