Unfortunatly they are all programed to self destruct in they belive that they have given too much information to a primitive race
Talk about irony. I love it!
Individually researching every pod you want to open would be far too much effort and time,
That's because you are imagining many sentinels, I only think a few. I see others want low-level sentinels that provide little raw resources...etc. For me it was always...whoopty do, 25 creds.
How about making 3 different types of sentinels (all are same size on the outside and different size on the inside, orion technology and all)
Lvl 1 - Resource caches, automatic buidling
Lvl 2 - Knowledge Cubes, magnate civs (if we have them)
Lvl 3 - Space Ships, Gaia, 5th X...etc, some really good bonus that you cannot obtain otherwise
Lvl 1 - Common (with some probability table. Probably more than one should be allowed per planet, but there should be a ceiling)
Lvl 2 - Uncommon (10%?)
Lvl 3 - Rare (2%?)
When you encounter Lvl 1 you get an option to research Lvl 1 sentinels. Once you have that, you can open all Lvl 1's. Same for Lvl 2. Lvl 3 sentinels would require individual research.
