In order to get this achievement you will need to completely finish this game on hard. There are a few tricks which i used to help myself to get this.
- Dodge Like Crazy, When Incoming Projectiles are coming in your path dodge, and then dodge again. Believe me sounds crazy, but it will work. You can shot while dodging so that helps in terms of dodging and shooting and using it to your advantage.
Killing Enemies From Great Distance - Yes, this is most likely one of the ways which help me survive, You save health. Which is you really need for such encounters, e.g. Bosses
Completing the Game on Lower Difficulties - This might level the playing field, considering some of the upgrades help alot during your harder playthroughs. So this might be a wise action to take before going on to this difficulty,
