Alien Virus vs Portal

Alien Virus is a classic 1995 point-and-click adventure game developed by Trecision S.p.A. and published by Softgold Computerspiele GmbH. Players step into the shoes of pilot Joshua Stone, who arrives at Station Zeus after a month in hyperspace only to discover the entire space station completely devoid of life. Navigate through eerie, deserted corridors, solve intricate puzzles, and piece together the dark mystery behind the empty station. Blending science fiction and horror elements, the game delivers an atmospheric single-player experience steeped in suspense and classic graphical adventure mechanics.

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.
