Star Trek Customizable Card Game 1st Edition
Impulse Speed Rules

Basically, they are the Warp Speed rules with the following exceptions:
1. Use 2 space and 2 planet missions.
2. For a full win you must score 3 missions.
3. The 20/25 rule means a maximum of 20 seed cards and a minimum of 25 in the draw deck.
4. You can use 12 dilemmas + 1 outpost or 13 dilemmas if a built-in outpost is used.
5. Seeding one Personnel, Ship, or Equipment card (your choice) means one less dilemma.
6. Seeding one Artifact means one less dilemma.
7. So, 7 other non-dilemma, non-personnel, non-ship, non-equipment, non-artifact seed cards can be used.
8. A Nebula is placed at the midpoint of the spaceline.
9. Each round is 45 minutes.
