How to unlock the Hardcore G.I. JOE achievement in G.I. Joe: The Rise of Cobra - Definitive Guide
For this I used Baroness and Destro.
First off both their abilities are pretty powerful and for some odd reason they seem to spam multipliers quite easily so if you are going for high scores or to unlock more characters I highly suggest unlocking these two first and running through the game on hardcore.
Lastly everything must be done in hardcore, including the bonus levels that you unlock. I played through all the normal levels on Hardcore and it did not pop, but when I went back and played the bonus ones and completed them all on hardcore it popped.
Self-explanatory. You must beat every mission on Hardcore Difficulty. You may not revive a downed Joe at any point on Hardcore. A great character combination to use is Ripcord and Gung Ho. Gung Ho will knock enemies down when he hits them with his primary weapon. Ripcord's special is a turret and will allow you to pelt the enemy with fire whilst you remain on the defensive. You can also stack specials, so you can get multiple turrets going at once. USE RIPCORD. He is the best character in the game and his special is an absolute life-saver.
Keep your distance from EVERYBODY and move slowly through the areas. Always look for permanent cover as the others don't last long. I found it MUCH easier to finish missions solo when playing on Hardcore. You can switch back and forth between characters with . The character you are NOT controlling can take unlimited damage. This character will also regain health more quickly than a character you are controlling. Learn how to switch back and forth effectively to prevent any Joes from dying. Check the walkthrough videos linked at the top of the page. This trophy will pop after the Mission Select screen has loaded upon completion of the mission.
