There aren't any
All skulls are automatically unlocked for Halo 3: ODST due to gameplay reasons.
if you want to know where the skulls are all you have to do is go to youtube and put in "halo 3 odst mythic skulls" and it will show you how to get to them
Yah I did the endure achievement 2 days ago. It was hard but now i got recon armor.
You unlock the odst armor by unlocking the UNSC SPARTAN achievement
ODST and Mark V armor are the ones.
Sorry there arn't any, The only skulls are in "Halo 3" Which are used in "Halo 3 O.D.S.T."

Sadly, No. There are secrets, like the skulls for example. The skulls are cheats, but there hidden through out the level, and some, you can only get on specific difficulties.
No there isn't, the ODST is just a Helmet there is no body or shoulder to the armor. To get the helmet just play online until you get to the rank of private which can take as little as 4 games.
To get the recon armor you have to complete all the vidmaster achievements in halo3 and halo3 odst.
No, you dont. You will have to do other, as of know unknown, achievements in Halo: ODST to get Recon armor.
well first you have to have xbox live and win a bunch of matches. i have all the armor b you get katana by getting 1000 gamerpoints in halo 3 same with security helmet. you get haybusa by finding all the skulls. eod by completing the campaign on legendary markv by reaching sergent in xboxlive. same with odst. and that's all i know
