Overload is a 3D first-person shooter video game developed and released by Revival Productions for Windows, macOS and Linux on May 31, 2018.

The game is set primarily on the moons of Saturn, where facilities have sent out distress signals about the mining robots turning hostile.

[2] The player is tasked with controlling a gunship in zero gravity inside a variety of mining facilities and cave areas, fighting hostile worker robots (called autonomous operators in the game) and finding possible survivors in cryostasis tubes.

The levels also contain a variety of secret areas behind camouflaged doors, some of which may be locked and require a puzzle to be solved in order to unlock them.

[4] Upgrade points are scattered around the levels, mostly behind secret areas, and are also given for completing certain tasks, such as finding all of the survivor cryostasis tubes.

The campaign story features full voice acting in English, with subtitles available in the other languages supported by the game.

Saturn’s largest moon Titan houses the majority of the colonial population along with the astrophysics, manufacturing, particle physics, metallurgical, and administrative operations.

Lastly, the inner moons of Tethys and Enceladus hold the colony’s secretive advanced research and gas mining operations, respectively.

The unnamed protagonist awakes from cryostasis with neurological damage and amnesia, and is informed by Mara, a self-described synthetic intelligence construct on the Iberia, that the vessel is now in the orbit of Ymir and has arrived to help those in the mining facility on the moon after receiving a distress signal from its staff.

The distress signal stated that the autonomous operators used for mining and security purposes have malfunctioned, turned hostile, and attacked the human employees currently working inside the facility.

The protagonist is supplied with a Kodachi light gunship, a small, highly maneuverable but heavily-armed spacecraft capable of navigating the mines and installations of Chronus Frontier.

After the initial rescue operation at Ymir, the player quickly becomes aware of the contentious relationship between Chronus Frontier CEO Gabriel Kantor and parent company Juno Offworld.

At the outer moons, the player discovers that Kantor ordered a massive buildup of security-based auto-ops as well as the development of new military-grade operators, believing that the colony was under imminent threat of attack.

Kantor apparently became increasingly belligerent and abusive to his engineers and scientists, demanding that they risk their lives to complete the new projects.

At the administrative complex of Titan Harbour, the player discovers that a hydro-geologist named Harper Eames, who was working closely with Kantor on a mysterious project on Enceladus, secretly requested that a small shipment of unknown contents be transferred to the Iberia along with shuttle pilot Alex Warden shortly before it departed from the colony.

En route, Mara recovers an audio-log from the chief scientist on Tethys, revealing that a crashed alien craft was discovered in the ice below the Enceladus facility.

Finally proceeding to the last-remaining base of Enceladus to confront Kantor, the Iberia receives another message from Juno Offworld Headquarters.

The player nearly intercepts Kantor at the alien craft excavation site, but discovers that he has reconstructed an interstellar portal connecting to a different part of the galaxy.

Unshaken, Warden destroys the first sovereign and finds a portal to return to Ymir, which is being utilized by the alien machines as a staging point to launch an invasion of humanity.

If the player rescued a majority number of survivors from Chronus Frontier, they will construct a warhead and fire it from the Iberia to annihilate Ymir along with the third sovereign.

[1] A 'playable teaser' was released on March 7, 2016 via the Steam distribution platform[21] and a second demo showcasing VR features of the game was demonstrated at PAX west in September.

[24] Revival Productions closed their doors after Overload was released and merged the company back into Volition Inc./Parallax Software.

[31][32] On release, the game received positive coverage from Rock, Paper, Shotgun and Engadget, with Dominic Tarason of the former calling it "very good".
