In the first of a series of videos covering Killzone 3's multiplayer professions, Guerrilla Games multiplayer designer Dan Nanni discusses the engineer, the game's turret-building support class.

Whenever I see any form of the word 'engineering' associated with a video game character class, 'complicated' is generally the next word that pops into my head. From the robot-crafting class in Funcom's sci-fi MMO Anarchy Online to Team Fortress 2's wrench master, these titans of industry generally leave me feeling unfulfilled at best, confused at worst.

It's not their fault, however. It takes a special kind of player to give up some personal firepower and survivability in favor of building machines that do massive damage to the enemy. I prefer to heal or do damage directly myself, but I appreciate our grease-covered friends for what they do.
