Event HORIZON is an open-world first-person/third-person sci-fi shooter game developed by Infinite Development Incorporated and published by IDI Publishing. Event Horizon will be available on the Playstation 4, Xbox One, Microsoft Windows, Mac OS, Wii-U, and the MPHES (MPHES). It is set between 2093 and 2117 during the First Colonial WarEvent HORIZON is set to be the first game of a trilogy, with the next game being Project CRUSADE.


It's 2093, humanity has expanded across the Milky Way Galaxy. Since 2056, humans have been colonizing distant worlds, all unified under the Galactic Alliance. In recent years, contact between some colonies and Earth, the human home world and capital of the Galactic Alliance, has ceased entirely. With most Alliance worlds' worried of an outside threat, the Galactic Alliance sends search and rescue forces to the colonies in order to reestablish contact with them.

After three months, seven of the original thirty search and rescue squadrons return with grave news. The colonies have gone rogue and are not taking any contact from the Galactic Alliance. Before the Galactic Alliance military can take action, Alliance worlds are attacked while the Council receives a transmission from Arnold Gershwin, self-acclaimed leader of the newly formed Interstellar Dominion. Arnold explains that the Galactic Alliance had not successfully completed their job of making an equal and unified galactic community and that it was only a matter of time before another form of power took its place. He then concludes with the execution of the last Galactic Alliance diplomat on Titan.

In response to this message, the Galactic Alliance Council declares war on the Interstellar Dominion, sparking the First Colonial War. They then order Field Commander Johnston, his crew, and other Galactic Alliance forces to make strikes against the Interstellar Dominion, prevent the capture of Galactic Alliance worlds, and take those that are lost back. For twenty-four years, Johnston and his crew assault Interstellar Dominion forces, prevent counterattacks, and take back captured worlds, which constantly infuriates Gershwin.

In 2117, the Galactic Alliance Military engages the Interstellar Dominion Military for the last time over and on the world of Titan. At the start, the Galactic Alliance Military begins taking heavy losses, including General William Paxton, commander of the Galactic Alliance Navy. In the end, Johnston takes command of the Navy after the loss of General Paxton and successfully destroys most of the Interstellar Dominion fleet.

However, Gershwin's ship, the IDN Imperius engages the GAN Savior in a massive gunfight. With the crew of the Savior able to destroy the Imperius' shields and main cannons, Johnston leads a team aboard the Imperius to capture Gershwin. Gershwin refuses to be taken and takes Johnston one on one by sealing the rest of the crew outside of the command room.

In the ensuing fight, Gershwin initially gains the uphand by disabling Johnston's shield generator on his armor and beating down on him with improvised weapons. However, Johnston is able to thrawt the beatings and severly wound Gershwin by impaling him. As a last resort to destroy the rest of the Galactic Alliance Navy, Gershwin sets his ship to detonate all munitions on board. Luckily, Johnston manages to disable the countdown, and Gershwin finally succumbs to his wounds.

Later, on Earth, General Billy Melchiott of the Interstellar Dominion Navy becomes the leader of the Interstellar Dominion and negotiates a peace treaty with the Galactic Alliance and the United Federation of Systems where all three entities can co-exist with one another.
