In Deus Ex Human Revolution can you keep earned "augs" to start a new game?
Solution 1:
Nope. Deus Ex Human Revolution has no "NewGame+" option. Every playthrough has you starting from scratch.
UPDATE: The Director's Cut version of the game does include a newgame+ mode.
Solution 2:
Whilst there's no official way of doing it, I wanted to do this as well, so I kept track of which augs I had, and then downloaded a trainer. I used the trainer to give me the exact number of praxis points I needed to re-purchase all my augs, and then started play.
Technically it's cheating, but as there's no multi player for Deus Ex I don't feel bad about it, and it hasn't affected anything on my steam account to date.
