Let me rephrase that.
How the hell did you have the patience to find 350 blast shards? Plus, the stunt involving sticking a flying enemy is pretty much impossible, killing 25 enemies while on a train would be time consuming and annoying, and getting an enemy to THROW a grenade is a herculean task, let alone shockwaving it back at precisely the right time and position while he is on low health to KILL him! (plus the other two stunts the game won't show me- I finally managed to do the grenade one on my Evil save file, I would have to do it on good again, because stunts don't carry over 
)
I believe those are the only ones I have left (All of the blast shard ones, no I don't even have 25% of them)
