I only made 8 so I could easily fit them on 1 page, and also because I didn't anticipate a need for more than 8 different combatants in initiative at once.
Aliens could go on two separate cards each, so a crew of 5 and 2 xeno-combatants will be 9 cards, 11 if the Queen shows up mid-battle. BUT these absolutely look very cool.
Ha! Yeah... I'll have to dig into my files and see if I still have the original project. Maybe I'll get around to adding a couple extras at some point.
