Savage Moon Walkthrough - PS3 Forums
I think it best that you at least try a few times to complete the missions before going to these walkthroughs as this is a great game and it'd be a shame to miss out on it.
The game is separated into 3 different Moons. Xipe, Ymir and Zeus
XIPE (1st Moon)
Xipe is essentially a tutorial, with the last mission on xipe (Overgar) being the first challenging mission, unfortunately there are no walkthroughs for any of Xipes missions yet, once some go up, I'll make sure to update the OP with them.
