Engineers are important members of their team, using their repair tool to make ammo boxes for their team, and building turrets to kill enemies and block areas, while using their machine guns to mow down any enemies they encounter. Engineer's are most important in objective based game modes where their turrets allow them to easily hold off enemies, or depending on their ability level hack and take control of enemy turrets.
- Engineers should watch out for Marksmen when repairing or building a turret since they can't move while their doing it.
