Here is my 100% Achievement guide.
The main and best advice i can give is constantly hit the
&
buttons simultaneously.
That way you never die, as long as you keep dodging, you never die.
Not long into chapter 1, you go up into a large room with enemies flanking you on your right, and some a bit further ahead of you south next to some motorbikes (Where the game teaches you about environmental killing).
Right here there is a bar you can go into.
Remember to LB & RB your way through the bar, as there are about 4 or 5 enemies here.
You do hit a checkpoint when you enter the bar though, so be careful if you do die, always make sure to LB & RB.
When you clear the bar of all enemies, in the top right room is a big sign with the name "Sons of Subversion".
Simply stand next to this to unlock the achievement
This should only take you around 5 minutes or so to complete :)
Hope this helps :)
