Thankfully, players have the Engineer as a secret weapon. Insanity will force players to use everything in their kit if they want to survive. Enemies have more health and shields, deal more damage, and are far more aggressive with their tactics. On Insanity, players will face a far more formidable fight for Shepard. For Mass Effect: Legendary Edition players eager for the coveted Insanity trophy, they will have to take on Mass Effect 3’s Insanity mode, its most difficult setting, and of all available classes, Engineer may be their best bet.
