Energy Trap is an ability that Hayden gains during Chapter 3. It allows him to "trap" an element such as fire, ice, or electricity in his Glaive, which lets him use it to solve environmental puzzles, take out enemies more quickly, or to use Energy Pulse. Simply throwing the glaive into an element such as a burning truck or an overloading circuit breaker is enough to charge the glaive, and from there the element can be used for any purpose, such as opening a locked metal door or freezing water to form cover.
