Jammer

Jammer is extremely useful for many different reasons. You won't need to use Bricks and Bottles to disable Traps, as the Jammer can be used to hack Traps so that they trigger for enemies and not you. You can also unlock locked doors and containers, and even hack enemies to temporarily stun them and make them vomit. One of the best uses of Jammer is how it can revive both yourself and teammates if you die, which basically makes the Jammer an extra life!
