I typically like to unlock all the upgrades before starting New Game+, however i'm at like 92% completion and i still have most of the gadget upgrades locked. If i collected all the Riddler trophies and complete all Most Wanted missions should i have everything unlocked?

Did you get the freeze grenade? Its not part of the story and unless you just happen upon it, you wont get it.

Very doubtful, unless you really grind XP non-stop. I got everything done on my first playthrough and still had about 6 or 7 upgrades left.

So no, just jump to NG+ when you feel you're done.

@strife777: Thanks! I still want to complete all the MW stuff but the last couple mines and the APCs are a bitch.

Yeah, I watched my husband 100% the game and even then he doesn't have all of the upgrades. I think it's intended to take you into NG+ although that's only a guess.

I'm also about 92% and only have 3 of the upgrade trees filled up (of the 6-7?). Doesn't seem likely you can do it in one playthrough. I only have riddler trophies and some of the murder investigations left.

I've gotten all the upgrades in one play through, it was very difficult. Now I've got a ton of excessive points and can't use them. Wish I knew what to do with them. Anyone have any ideas?
