Assassin Techniques are unlocked in the order that they are listed, no matter which level you play. Techniques are not tied to certain levels and there are far more levels that you get scored on than there are techniques. If you are having trouble getting a good enough score for one of these techniques, skip it (or check our walkthrough).
