Codename: Iceman vs Portal

Step into the boots of Johnny West in Codename: Iceman, a gripping graphic adventure and simulation hybrid designed by Jim Walls. Tasked with rescuing a kidnapped U.S. ambassador from radical terrorists, you must navigate a dangerous global oil shortage and high-stakes superpower conflict. Utilize authentic Naval intelligence charts and master a realistic nuclear submarine simulator to penetrate enemy waters undetected. This Sierra On-Line classic merges classic point-and-click investigative gameplay with tense tactical navigation for a unique retro challenge.

Portal is a first-person puzzle game developed by Valve. Players take on the role of Chell, a test subject who awakens in the Aperture Science computer-aided enrichment center. Guided by the sadistic artificial intelligence system GLaDOS, Chell must navigate through increasingly challenging test chambers using the 'portal gun,' a device that can create two portals that allow for instant transportation between them. As Chell progresses through the game, she uncovers the dark secrets behind Aperture Science and must use her wits to escape the crumbling facility.
