Alter Echo vs Portal

In Alter Echo, players step into the shoes of Nevin, a warrior who can physically alter an organic material called Plast and manipulate time itself. Stranded on a planet where illegal experiments have infected Plast with human consciousness, Nevin must fight wave after wave of biomechanical enemies to save humanity from the rogue shaper Paavo. The game features dynamic combat that allows players to seamlessly morph between Melee, Gun, and Stealth modes. Coupled with an innovative Time Dilation system that lets you freeze action and queue up devastating combos, Alter Echo delivers a unique blend of science fiction storytelling and action-packed gameplay.

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.
