Fuze is best played as an aggressive flanker and area denial Operator. His strengths allow him to dispatch defensive capabilities and harass enemies anchored in defensive positions. Fuze's APM-6 cluster charge propels a group of explosive cluster grenades through any soft breach surface.

Cluster Charge
Fuze is good for more than just killing defenders. His cluster charge can destroy all gadgets placed in a defensive stronghold. If you can get above a hallway or room full of barbed wire, traps or defenders, your cluster charge will shoot small charges that will guarantee an easier entry later in the round.
Defenders have a few seconds to get away or take cover from the damage of the APM-6 cluster charge. They will often take the shortest route. Be ready with a line of sight and pick them off one by one as they run to safety - strong to counter anchor players in predictable spots.
The cluster charge might seem chaotic, but it's more predictable than you think - it will always disperse in a fan like pattern, starting from left to right. How you place it in will greatly impact the spread and area covered by the Cluster - experiment with this and learn to cover as much ground as possible.
