Usually, most in-game weapons serve just one purpose, or at most two, mainly dealing damage depending on how you use them. But some weapons are designed to be way more versatile, packing so many functions that you might never need to switch to another weapon. Here’s a list of the top 10 weapons that let players wipe out any opponent with ease.
Mega Man’s Mega Buster – Mega Man Series

Rock was originally created by Dr. Light as a combat robot, but later the doctor wanted to make sure Rock could survive any situation. That’s why he developed the Variable Weapon system for Mega Man’s Mega Buster arm.

By copying data from defeated Master robots, the Mega Buster can transform into multiple forms and fire different types of shots. These powerful shots require a cooldown, but this weapon system also inspired the transforming weapons in Mega Man X.
Pandora – Devil May Cry 4

After defeating Dagon and destroying the hellgate in Fortuna Castle, Dante gains a very unusual demonic arm. Though it looks like a small briefcase, Pandora in Devil May Cry 4 can transform into 666 different weapons, boosting Dante’s freeform combat style. Some forms include spinning blades, Gatling guns, rocket launchers, and even artillery cannons.

Ironically, Pandora’s most powerful form is its original one, the briefcase. Just opening it unleashes a powerful light beam that instantly wipes out any unlucky enemies standing in front of Dante.
The Axiom Disruptor – Axiom Verge

When scientist Trace finds himself trapped in a strange alien world, he acquires a bizarre biomechanical weapon called the Axiom Disruptor. This weapon fires laser-like beams similar to a rifle and can be upgraded with deadly new functions like energy saws or explosives.

Its most overpowered ability is the Address Disruptor, which lets Trace literally manipulate reality by warping the space around creatures and terrain into strange shapes that give him a huge advantage in combat.
God Arcs – God Eater Series

In the God Eater universe, Earth is ruled by Aragami, giant monsters made from Oracle Cells. These beasts are ravenous, ready to devour anything nearby. To fight them, the Fenrir Organization created God Arcs.

God Arcs are alive and hungry like the Aragami, able to grow mouths that bite enemies to pieces. When well-fed, they gain power and can transform into various melee and ranged weapons. Even their bullets can be customized to follow different trajectories with unique effects.
Omni-Tool – Mass Effect Series

The Omni-Tool is a sleek, high-tech device frequently seen in the Mass Effect universe. Worn on the wrist, it can create various tools and gadgets. It serves as a flashlight, scanner, fabricator, and with the right tweaks, it becomes a deadly weapon for close combat.

The Omni-Tool’s basic weapon is the Omni-Blade, a formidable melee weapon. It can also generate shields, launch plasma orbs, set electric traps, and even fire freezing beams to stop enemies in their tracks.
