There are twelve different apps available during the co-op game while the campaign game only features three. Each of these apps can be upgraded by spending application tokens and then researching the upgrades.

Backfire

Backfire was one of the earliest applications developed. A basic link between the DART chip and an inanimate object is established and a certain function is executed.

In this case, the link is to a gun used by an enemy and the function is to change the timing of the trigger release, causing a misfire. This deals a moderate amount of damage to the target and knocks enemies back.
