I like the one that add the % bonus to some of the ships stats the most i hope Dan considers making it. the one from betrayer mission.
but the green containment missal would be good for this but in some games if you don't right the name exactly it gets wasted there should be a way to not let that happen like a if you don't fined some on it comes back to inventory.

i fixed it .

But that would not be a bad idea. A green condiment missal to to shoot at the enemy be for you eat them... yes that's right Sillixx will grill you up and eat you. Ever wonder what happen when your crew member dies during an invade.
WE EAT HIM 
so some thing to think about be for you invade me.
