The Engineer is a returning survivor in "Risk of Rain Returns" with a new ability that replaces a standard auto-turret with an experimental prototype laser turret that charges up over 8 seconds before unleashing a huge 1200% damage laser blast. However, this ability has a drawback as it rapidly damages itself and will be completely destroyed after a single shot unless the player can find a way to repair it. Overall, the Engineer has one of the strongest single abilities in the game, making him a formidable character to play with.
