The alien tech cards allow you to bend the basic game rules. Most alien tech cards may be used immediately after you acquire them. Alien tech cards that require a fuel payment can only be used once per turn. You may only discard an alien tech card you have not already used on your current turn and then only one discard per turn.

Your alien tech cards are placed on the table face- up where all players can see them. You may only possess one copy of each alien tech card.

If a card allows you to change a ship's value then the value may never be lower than 1 or higher than 6. If the alien tech draw deck is exhausted, reshuffle the discards to create a new draw deck.
