Ok, went through the 2 success logs I have here and in both instances the following was true:
1. Tachyon played at least 10 cards in a single turn.
2. Tachyon did no Sonic damage to Progeny.
3. Tachyon reshuffled her deck at least twice.
4. Tachyon was incapcitated
5. The Vanilla Freedom Five was used
6. Both were in Megaloplis (which I think we've all figured out is going to be a requirement for all the FV unlocks).
7. Both were victorys (which I think we've all figured out is going to be a requirement for all the FV unlocks).
So here are the conditions I'm assuming right now:
1. Meet the pre-req games.
2. Win against Progeny in Megaloplis with the Freedom Five (Standard)
3. Tachyon must be incapactitated
4. Tachyon can not deal sonic damage to Progeny
5. Tachyon must reshuffle her trash at least twice
6. Tachyon must play at least 10 cards in a single turn.
Things to test:
1. Can Tachyon deal Sonic damage to Progeny?
2. Is a reshuffle required and if so how many times? (this seems to go against what you would do in a normal game though)
3. Can Tachyon play less than 10 cards in a single turn?
4. Can Tachyon still be standing at the end? This one I doubt because of the story, but it may not require an incap.
