About The EVA Engine: Upgrade 1.5, from BoardGameGeek:
Version 1.5 of EVA Engine represents a significant evolution of the core game. Think of it as a refined and enhanced experience, building upon the foundations of the original while introducing key improvements and additions. In essence, EVA Engine 1.5 is the definitive way to experience the game.
One of the most noticeable changes is the updated rule set. Based on player feedback and further design considerations, the rules have been streamlined for greater clarity and smoother gameplay. Additionally, Version 1.5 boasts a completely new graphic style. This isn't just a minor facelift; it's a reimagining of the game's aesthetic. And, Version 1.5 may also include the first-ever expansion for EVA Engine (depending on number of backers).
The game consist of doing whatever you can to bring (move) the correct element in ascending numerical order to the position 5 (repairing chamber) and repair it, before your time runs out. If your time is up, or you have to place a heat token while your stock is empty, you lose the game. The game's design incorporates scalability, allowing you to fine-tune the difficulty to perfectly match your personal taste or level of experience.
Beyond new components, the 1.5 upgrade introduces a fundamental shift in how you interact with the game's resources through a new mechanic we call 'Resonance Cascade'. The energy you generate from one action can now ripple outwards, potentially fueling another.
