Players can make them significantly more powerful with upgrades and mods. Shotguns are particularly deadly at close range, making them an ideal choice for classes like Soldier, Engineer, and Vanguard who tend to get up close with enemies. These weapons mods improve or increase a weapon's stability, accuracy, magazine rounds, and damage output. In Mass Effect 3, all weapons have mods that can be purchased or found during missions. Mass Effect: Legendary Edition removes class restrictions on weapons, meaning players have access to more options than ever. To fight the more difficult Reaper enemies like Banshees and Harvesters that appear in Mass Effect 3, Shepard and their squad will need to get better equipment.
