I was playing Halo 3: ODST the other day...

[I'm a busy person, I can't beat games in one setting.] ...And my brother and I were finishing beating the game on Heroic. We did what we were supposed to do and investigated whatever it is we were supposed to investigate, and the 360 makes that noise that it makes when you get an achievement. You know, the *blooup* kinda noise. Anyway, my brother looks at me with a confused expression and reads the little thingy that popped up, telling us what we got.

It said, 'Super Sleuth for 10'. My brother's jaw dropped and he looked at me and pressed the middle button, and sure enough, we had gotten the said to be 'hardest achievement to get in ODST.' My brother laughed his butt off.

Here's a link, I'm ZettaGin if you wunna add me. Just tell me who you are so I'll know: Clickety Clickety Clack.

 

where may i ask is the final clue i seem to be unable to find it.
and thats a prety good achievment but i think the hardest is probably vidmaster deja vu achievment

took me a good hour to get it lol

I haven't a clue where it is. We got it by accident.
