Double Dragon Neon

The Sosetsitsu are the offensive tapes that you use with RB.

To be on the safe side I never equipped one at all until I had finished the game, I did however, equip a stance and can confirm that equipping stances does not void the achievement. I also recommend that this be attempted on 'Normal' difficulty as Dragon difficulty is quite a step up.

I did this on my first runthrough and the achievement unlocked during the credits. I am unsure whether replaying every level without using any Sosetsitsu will still unlock the achievement (If someone confirms I will credit them and add to solution).

Edit: Credit to 'EliteEdawg420' and 'FL trooper' for confirming that replaying every level without using Sosetsitsu will unlock the achievement.

Edit 2: Credit to 'rockanroleiro' for his tip that if if you want to be extra cautious to not risk pressing RB by accident you can equip Knee Drop, which does nothing when RB is pressed unless you have jumped and are in the air.

Tips for Gameplay
1) Make use of enemy weapons
2) break Everything you find for health and extra lives
3) If an enemy has predictable moves wait and try to get a 'Gleam' or evade the attack before pummeling them.This saves a lot of damage being taken and if Gleam is activated you deal Extra damage.

Note: the Final boss has an attack which is essentially a 1-hit KO. When you see 4 white lights appear on the ground beneath you, wait at the edge of the lights until the last second then dodge roll away and you can survive it.
