Single Player: Kill 10 enemies in a single Supercharge boost [Silver / 25G]
Location: Mission 7 This can be done in the last mission. Before starting the final boss fight you have to supercharge your nanosuit by stepping into alien generators. This is a main objective and cannot be missed. After using the second generator you should go for the 10 kills. Use the visor to locate enemies while making your way to the next main objective. While being supercharged you cannot take any damage and alien weapons have infinite ammo. The supercharge runs out after some time, so you need to hurry up.
