If you're the type of player who always thinks they can do a little bit more for the planet (or rather, the Red Planet), the Teslaract promo card is your new favorite toy. This special card, originally released during the Prelude 2 Kickstarter, is a collector's item that brings a very interesting strategic boost to your journey on Mars. It's not a full expansion, but rather an additional component that joins your card deck to add some extra spice to your production engine.

The mechanic here is straightforward but requires that strategic thinking we all love. With Teslaract, you can perform a clever resource trade: you decrease your energy production by 1 to increase your plant production by 1 step. Sounds like a sacrifice, right? Don't be fooled! By making this transaction, you also raise your TR (Terraforming Rating) by 1 step. In other words, you're trading an industrial resource for direct progress on the board and scoring. It's the kind of card that helps accelerate the process of making Mars habitable, focusing on the biological aspect and your prestige as a corporation.

Since it's a promotional card, it's a must-have item for those who want every possible play option on the table. It brings a 'fine-tuning' dynamic to your economy, allowing you to direct your resources exactly where they are needed most during the game. If you enjoy optimizing every step of your engine and want every tool possible to dominate the solar system, this card is an essential find for your setup.
