Echo

The Echo experience sees the player traversing endless corridors and chambers, mostly traveling further down into an endless superstructure. The early game allows the player ample time to learn each of the tools as they become available, as well as solving puzzles, but before long enemies start presenting themselves.

The game's most key facet is consequences for one's actions: whenever a blackout occurs, anything En does during the previous lights-on period will become available to the Echoes prowling the Palace. For example, if sprinting while the lights are on, after the system reboots the enemies will become able to sprint. The same is true for opening doors, crossing water, vaulting, and using weapons or stealth. Conversely, they will not be able to use any unused actions during the previous lights-on period, and will thus unlearn previously learned abilities.

Echo takes place in a far-distant future; during the Push Era, technology quickly advanced, allowing humanity to colonize distant systems and planets in a period known as the Requisition Rush. Vast artificial intelligences and genetic enhancement are among the many sciences that approach magical levels of capability in this time.

En is a young woman from the "Resourcefuls Program": genetically modified humans created by her mystical grandfather "Gramps" to be capable of always succeeding, no matter the challenge. She travels with a bitter and pessimistic AI named London, who had previously partnered with a man named Foster; London initially despises En for her involvement with Foster's death, but comes to respect and even care for her.

Echo received "generally favorable reviews" based on 24 critic reviews, according to review aggregator Metacritic. 62% out of critics recommended Echo on OpenCritic.

Echo won four major awards at "Spilprisen 2018", the Danish Game Awards - Best Visual Design, Best Sound, Best Technical achievement, and Game of the Year.
