About Event Horizon

Venture beyond the stars in Event Horizon, an electrifying free-to-play indie adventure that redefines browser-based space RPGs. Set in a sprawling procedurally generated galaxy, this game throws you into an immersive sandbox where curiosity is rewarded and every mission shapes your legend. Whether you're a casual explorer or an aspiring fleet admiral, Event Horizon blends intuitive gameplay with deep customizability and limitless tactical choices.

Command your very own customizable fleet as you journey across millions of stars, each sector brimming with hostile forces, uncharted phenomena, and lucrative opportunities. The heart of Event Horizon is its stunning modular ship-building: equip your vessels from a mind-blowing arsenal of 250 unique modules and weapons—lasers, plasma cannons, stealth shields, adaptive thrusters—with each combination opening fresh gameplay avenues. Your choices matter: clever builds and well-suited upgrades mean the difference between total domination and cosmic calamity.

Dynamic faction interactions add layers of intrigue to your space odyssey. Will you align with influential traders, daring rebels, or fierce armadas, or carve your own rogue path? With easy-to-grasp controls and accessible mechanics, Event Horizon is perfect for jumping right in—but beneath the surface, a strategic depth beckons seasoned players to perfect their fleets, optimize resource routes, and outsmart rival captains.

Playable in any browser and fully mobile optimized, Event Horizon invites you to play anywhere, anytime—no downloads required. Its striking, polished pixel art aesthetic pays homage to retro sci-fi classics, while modern effects and fluid animations pull you into the action. Frequent updates and a passionate community on itch.io ensure there's always some new cosmic mystery to unravel.

Whether you're charting distant realms, hunting powerful loot, or gunning for leaderboard fame, Event Horizon delivers heart-pounding adventure and unending possibilities. Build, explore, battle, and rise through the ranks—space is yours to command!

How to Play

Getting started in Event Horizon is thrilling yet accessible, perfect for both newcomers and galaxy-hardened veterans. As you launch the game in your browser or on mobile, a quick tutorial introduces you to your mothership and core UI elements. Use the intuitive point-and-click or tap controls to navigate the star map. Zoom in and out to scan star systems, and simply click or tap a destination to move your fleet.

Every star system hides opportunities—missions, battles, resources, or interstellar mystery. Approach mission points to trigger objectives: escort, bounty hunts, trading, or exploration. To engage in combat, select your target and unleash your ship’s arsenal with one easy click or tap. Master real-time tactics: dodge incoming fire, use ship abilities, and outmaneuver foes!

The heart of your progression lies in fleet building. Dock at stations to access the shipyard and customize your ships. Drag-and-drop modules and swap weapons freely; optimize each vessel for your favorite playstyle, from agile scouts to hulking dreadnoughts. Upgrade modules using loot and currency earned from missions.

Don’t forget to monitor your fuel and resources as you plan long voyages! Beginners should experiment with ship builds and take on easy missions while discovering the galaxy. The game's easy difficulty ensures a gentle learning curve, making early victories rewarding and motivating deeper exploration.
