InFamous trophy guide discussion

[RafaelOrix]

Thanks for it! I love exploring maps, so I think collecting all the blast shards won't be a big problem, buuuuut, just in case, can you send me that map? lol

I'm almost done with everything on the good side plus all the stuff from both sides, can't wait to replay the game being bad and get the Platinum. I'm having a little trouble with this trophy: Casey Jones - Take down 25 enemies while riding on a moving train. I'm not sure, but I think I'm on hard, but still this is annoying me lol. I have a question here: let's say I kill 20 enemies while on my first play, will I have to kill all 25 again or I'll need only 5 more to get this trophy on my second play?

Thx a lot for your guide!
