The combat system in GTA 5 and its Online component is pretty straightforward - the one with the better guns would have a massive advantage in fights. In this article, we would list out the top 6 most powerful guns in GTA Online.

6 - Up-n-Atomizer

Given away for free during the Festive Surprise 2018 event, you can buy this gun in Ammu-nation for $399,000. Unlike other weapons in the game, the Up-n-Atomizer is an alien Raygun that doesn't use normal bullets (it recharges after 2 seconds).

This gun fires an energy pulse that causes an explosion on the first object it hits. The shockwave would knock both vehicles along with NPCs and players into the air, dealing moderate damage. It is overall a perfect weapon for griefing, as you can knock enemies down repeatedly, leaving them no chance to respond.

5 - Homing Launcher

If those pesky flying vehicles are becoming a problem, get yourself a Homing Launcher in Ammu-nation for just $75,000. It fires infrared and guided missiles capable of knocking out any airborne and ground threat. After locking on target, you can just fire and forget.

The best thing about this weapon is that it is available at rank 1 - you should get it as soon as possible to fend off vehicles from your enemies.

4 - Minigun

The minigun is the ultimate "spam" weapon in the game, with 6 barrels holding 9999 magazines firing at an extremely high rate. Any vehicles, no matter how tough, would eventually be destroyed under a torrent of bullets spew out of a minigun.

In GTA Online, you will unlock the minigun after reaching rank 120 and completing the Paleto Score heist. It costs $50,000 in Ammu-nation.

3 - Railgun

The railgun is an extremely powerful and experimental weapon - it shoots faster than sound explosive bullets propelled by magnetism. One shot of this gun is more than enough to devastate any target. The weakness of this gun is probably its availability - you can only use it in a couple of modes except for the Free mode, the most important one.

You can get the railgun in the shop for a small price of $250,000.

2 - Widowmaker

The Widowmaker is a futuristic counterpart of the Minigun - it shoots plasma instead of ordinary bullets. Based on the numerous white alien skulls on the main housing, the Widowmaker is likely to have an alien origin. It is based on the Republic Space Rangers' plasma machine gun.

Its mechanics are about the same as the minigun except for the higher damage. You can buy the weapon for $499,999 at Ammu-Nation.

1 - Orbital Cannon

The most powerful weapon in the game - you literally pay tons of money to fire one shot. To get the Orbital Cannon, you would need to build a facility (cost about $6 million) and pay a further $900,000 to install. Each manual shot would cost you $500,000 and automatic would cost $750,000.

A single shot would cause the total destruction of targets. Nothing can hide from an orbital cannon - even if they hide three floors down underground inside their bunker.
