Hack the Robots
Very early on in Call of Duty: Infinite Warfare, the game will teach you how to use Hacking Charges on the robot enemies. These tools can come in especially handy when you’re facing off against a horde of robots, and will allow you to take out most of them in one go.
Whenever you’re up against these mechanical foes, hold down the L1 button or LB to view the available targets for hacking. You’ll want to focus on the one you want to hack, wait until its silhouette glows red, and then release the button to initiate the hack. This will give you control over the robot, and you can move it around and fire its weapons. More interestingly, you can also initiate a self-destruct sequence that will kill anyone who happens to be standing near it.
However, Reyes will be vulnerable whenever you hack, so make sure you’re behind aerial cover before you start.
