Serious Sam 4 is an incredibly absurd yet outrageously fun first-person shooter video game by Croteam. The game is known for its very fast-paced action, quirky humor, in-your-face combat mechanic, and the ridiculous amount of enemies the players will have to deal with at every turn. Serious Sam 4, despite receiving a lower reception compared to its predecessors, still managed to be really entertaining, and some fans managed to look past its many flaws.

A first-person shooter game wouldn't be exciting without having extravagant guns the players can equip. Thankfully, Serious Sam 4 has an abundance of incredible weapons, a few of them border lining the realm of insane.

10 Double Barrel Coach Gun

The Double Barrel Coach Shotgun is one of the classic guns, and it's no doubt one of the weapons fans of the franchise will instantly recognize. It doesn't do much in terms of aesthetics in comparison to the other weapons, but it sure as hell packs a substantial punch.

The weapon has a very useful "spread" that makes it effective in dealing with a horde of weaker enemies, especially those that tend to close in fast. It is also powerful enough to wipe out the bigger, tougher enemies if they are shot at a close distance in a shot or two.

9 Auto-Shotgun

The Autoshotgun acts exactly as it sounds; it's a shotgun that can fire at an automatic rapid rate. Interestingly enough, this weapon makes its first appearance in this game. Why is it interesting? Well, because it is very effective in clearing a number of enemies quickly, which is what this game has been known for since its creation. You'd think a weapon like this would have been integrated into the game earlier on, but its addition here is very welcome.

This weapon becomes even more effective once you dual-wield it, an upgrade you can acquire later on. It uses 12-gauge shell ammunition, and one reload can fire up to 20 shots.

8 SBC Cannon

A cannon as a handheld weapon that doesn't restrict the player's movements, as well as shot a couple of blasts in succession? This game has it. The SBC Cannon is a clearly overpowered weapon that is capable of obliterating anything foolish enough to stand across its massive barrel. This weapon has been present since the first Serious Sam game and is actually one of the main character's signature weapons.

This is one of the most perfect weapons to use in a shooter game where the player is constantly being surrounded by a horde of enemies. It can kill every small enemy it hits, and it may take a shot or two to kill the bigger ones.

7 XL2 Laser

The XL2 Laser Gun is an energy weapon available in Serious Sam 4. This gun was first introduced in the first Serious Sam game. It is called the Laser Cannon in Serious Sam's Bogus Detour. This weapon is highly powerful and is a great alternative to the minigun. Its only failing is there's barely enough ammo for it early in the game, but there should be quite enough once the player reaches the final act.

In Serious Sam 4, this weapon has an alternate firing mode called the Death Ray, which allows the weapon to fire a highly concentrated, single-focused laser beam that's capable of obliterating anything in its line of fire.

6 Psychotropic Grenade

The Psychotropic Grenade is one of the most fun gadgets Serious Sam has ever utilized. While it seems like a typical grenade at first, throw it towards a horde of enemies and watch chaos and fun unfold. The Psychotropic Grenade has a unique nerve agent that disperses upon landing. Enemies that become exposed to the smoke will start fighting one another. As the players of this game can imagine, the more monsters that get caught in this agent, the more chaotic the scene.

A weapon like this is highly useful in a game like Serious Sam 4, as it allows Sam to gather his bearings as his enemies are forced to fight each other. This makes its first appearance in this game.

5 FRPCL

The FRPCL, or F.L.A.M.M.E, is one of the many overpowered weapons of the game—almost too powerful. A weapon that's a rocket launcher, flamethrower, chainsaw, and a catapult all in one, it's bound to catch the attention of Serious Sam.

The weapon's most basic feature is a rocket-propelled chainsaw that uses a targeting system. As absurd as that sounds, it is also 100% accurate. The chainsaw rocket, upon hitting an enemy, will continuously hit it until they perish. It will also target another nearby enemy after killing the first target and will continue to do so until it explodes.

4 XM214-A Minigun

Minigun from Serious Sam 4.

The highly recognizable and the all too powerful XM214-A Minigun is one of Serious Sam's signature weapons. It has the highest rate of fire of any weapon in the game, which makes it highly effective when the player character is surrounded. That's a situation players will become familiar with as they play this game.

This is one of the weapons that has been present since the very first Serious Sam game. It's a weapon that fans of the franchise will expect to find whenever a new title of the series comes out. Whatever the case, a weapon like this most certainly belongs in a game like this.

3 XPML21 Rocket Launcher

The XPML21 Rocket Launcher is a perfectly absurd weapon in a perfectly absurd franchise. A weapon that has been there since the beginning of the franchise, this rocket launcher acts as an automatic weapon that fires a series of rockets without having to reload. As the players can imagine, this is highly useful when being engaged by a horde of enemies, many of them tower in size compared to the protagonist.

This weapon was designed to fire up to 85 missiles per minute. Just one missile is enough to obliterate the weaker enemies and a couple more for the bigger ones. This is also a perfectly ideal weapon to use against bosses.

2 Mini Nuke

The Mini Nuke almost needs no explanation. It is exactly what it sounds like. A nuclear weapon Serious Sam can use in combat. This particular weapon is the rarest one the players can equip in the game, and perhaps rightfully so. The Mini Nuke should only be used as a last resort and one blast from this weapon is enough to destroy every enemy type that will get caught in its blast.

The weapon can be acquired by completing a side mission called the "Morituri Te Salutant." This weapon is a testament that even though Serious Sam 4 isn't among the best FPS of all time, it is certainly one of the most entertaining to play as long as it isn't taken too... seriously.

1 Black Hole

A Black Hole you can use in combat. It is by far one of the most ridiculous weapons in video game history, but it is also one of the most entertaining to use. The gadget comes in the form of a crystalized black hole that Sam can throw like a projectile. Once it lands or hits an enemy, it will apparently cause a "singularity collapse" and will proceed to suck in all the enemies surrounding it, killing them instantly.

This weapon is one of the rarest ones in the game so it should only be used in the direst situations. It is highly effective in dealing with hordes of monsters and will surely save the players from an inevitable defeat if the horde becomes too much to handle.
