THE GAME
Mankind has expanded its reach beyond the Sol System. Factions, corporations and syndicates are locked in a political and economic strife. The inevitable destruction and decay of a colonized exoplanet is imminent.

beta decay is a dark, dystopian RPG where you can build spaceships, join factions, and fight for territory in a newly discovered star system. Live amongst the colonists as a citizen of the new frontier. Be an engineer repairing starships, to a syndicate leader, executing raids deep within a labyrinthic neon city.

beta decay presents city ruins and destruction at a scale. Deep within the earth, delve deep into a labyrinthic metropolis that is soaked with neon lights and dense crowds. Massive structures scrape the skylines that consist of Megatenements for housing and Megaplazas for corporate consortia.

Play in third and first person perspectives with seamless, fluid transitioning between the two. (No separate models or animations).
