The Firefly is a rocket launcher with a similar design to the HEV Mk 51, featuring moderate damage (but with maximum armor penetration). The Firefly, however features decent mobility and higher-than-average reserve ammunition (with a total of 5 rockets with the Boombastic skill fully upgraded).
In addition, the Firefly's special mechanic causes its rockets to detonate with a toxic DOT effect which lingers in the area for a few seconds. (The effect is comparable to that of the Toxic Area Armor Core. However, the Firefly's toxins linger in the blast area for a much shorter duration - approximately 5 seconds).
Overall, the Firefly is considered an underpowered weapon for its tier due to its mediocre-overall damage output, slow reload speed, and low mobility, leading to it being potentially surpassed by the COM 4 and SLAK 7H

Trivia Edit
- Around the time of its release, a bug was existed where Firefly despite being a prestige weapon, the icon when received a BluePrint from a weapon pack had a bronze background. The bug was fixed later on, now currently, the gold background is displayed when received a Blueprint of it from a Weapon pack which is the correct one.
