Exodus: Event Horizon is an expansion for Exodus: Proxima Centauri released in 2017 for 1–6 players, 90–180 minutes per game, and ages 14 and up. It was designed by Andrei Novac and Rainer Ahlfors and its main mechanics are Variable Player Powers, Dice Rolling, and Area Majority / Influence.
In general relativity, an event horizon is a space-time boundary beyond which no matter can escape; it is a "point of no return" past which nothing will be the same. Event Horizon is also the title of this expansion for Exodus: Proxima Centauri. Designed by Rainer Åhlfors and Andrei Novac, it marks a significant step in the Exodus universe! Exodus: Event Horizon is fully enjoyable when integrated with just the base game of Exodus: Proxima Centauri, but it also works great along with Edge of Extinction, the previously released first expansion for Exodus. Even though all ten modules herein are compatible with one another and can be used together, each represents a new or enhanced experience. While some modules integrate seamlessly, others will surprise and engage you in brand new modes of play. The expansion also contains two scenarios that provide brand new ways to enjoy the game, including both cooperative and semi-cooperative game modes, a flexible solo-mode, and a scenario that introduces timed game events. Module Summary Bonus Actions M1 This module adds additional Bonus Action cards as options in your games. Centaurian Resistance M2 The Resistance fleets have been reimagined to better scale in both threat and reward throughout the game. Centaurian Outposts M3 Centaurians are actively defending their planets against players who exploit their valuable resources. Exploration M4 Surprising events and sudden dangers await those brave enough to explore the unknown worlds. New Planets M5 New and exotic planets provide even more variety and choices as you expand the reach of your faction. Proxima Centauri M6 Our home star makes an appearance in the game and impacts the planetary system with solar wind. Jump Gates M7 Utility structures suitable for both strategic and tactical use as well as emergency response. Communication Satellites M8 With a strong communication network, your ships will gain an advantage away from home. Energy Barriers M9 Natural pockets of energy which can be both a hindrance and a boon. Leaders M10 Employ powerful leaders and benefit from their unique strengths. Scenario Summary Centaurian Stronghold Multi-Player, Fully Cooperative Challenging game mode where the players must work together to eliminate a Centaurian Stronghold megastructure while fighting against relentless waves of Centaurian Warship Squadrons that pursue player ships. No combat takes place between players in the fully cooperative game mode. Multi-Player, Semi-Cooperative Most of the scenario rules remain the same in the semi-cooperative game mode. The players can still collectively lose the game if they fail to eliminate the Centaurian Stronghold. However, both the Stronghold itself and the Warship Squadrons are slightly less deadly. On the other hand, they players are also competing against each other as normal. Solitaire True solitaire game mode where you can enjoy the full Exodus experience, with or without whatever expansion content you like. Event Horizon Multi-Player, Competitive New challenge mode where the players must attempt to score the most victory points before the planetary neighborhood of Proxima Centauri becomes uninhabitable. Triggered in-game events may end the game a turn or two early, requiring the players to always make optimal use of each turn.
