Review of the Nerf Rival Prometheus, an over-the-top blaster with intimidating looks, a huge magazine, and excellent performance.

The fully automatic Nerf Rival Prometheus is a one-of-a-kind blaster in the Phantom Corps sub-series of Rival, designed to intimidate, impress, and have tons of fun with.

Firing with the Prometheus is a unique experience, with only one drawback. Once you’ve tried it, you’re instantly hooked.

In this review of the Prometheus, I am walking you through some of the top features of this unique blaster, and I will share my honest thoughts.

You can purchase the Nerf Rival Prometheus on Amazon.

Let’s first decipher the fancy name of this blaster.

As I explained in my article about the best Nerf Rival blasters, the M in the name means it’s a motorized blaster, the XVIII bit means it was released in 2018, and the 20K bit indicates this blaster has a firing capacity of no less than 200.

Rival blasters (except for the latest ones) are also named after Greek and Roman mythological figures. In this case, the Prometheus was named after a Titan god of fire. That name alone, Prometheus MXVIII-20K, reveals so much about this blaster.

The Prometheus is a fully automized blaster in the popular Rival series that can hold a record-breaking 200 high-impact rounds in its magazine. It’s a rather expensive blaster, but the pricing makes perfect sense because it has a lot to offer.

As you can probably tell from the pictures, the Prometheus is a huge machine, created with only one purpose. And that is to have loads of fun.

Here’s my take on the ridiculously fun Nerf Rival Phantom Corps Prometheus.

1. Huge Magazine Capacity

If you were impressed by the firing capacity of the Nerf Rival Nemesis, you’re going to love the Prometheus. The Nemeses has a capacity of 100 high-impact rounds, but the Prometheus doubles that amount.

That’s right; the Prometheus has a firing capacity of 200 rounds, which, in a way, is kind of ridiculous. Over the top, maybe? I’m certainly not complaining because it’s so much fun to be non-stop firing 200 rounds, with virtually no jams or malfunctions happening.

The magazine is a so-called hopper, meaning the rounds can move around freely within the magazine and are being fed into the conveyor system. The hopper can be detached, but there’s no real need to do that since you can easily reload balls through a little door at the top.

2. Unique Ergonomics

As you’ve discovered by now, the Prometheus is very different from all other Nerf blasters out there, and that also applies to its ergonomics. You don’t shoulder the Prometheus or hold it in front of you. Instead, you’re basically holding this blaster with both hands at the hip level.

The Prometheus has two handles; one at the front and one at the back. The handle at the front (which is also removable) can spin, which means you can easily move the blaster up and down. It’s actually a really comfortable setup, and the blaster isn’t too heavy, either.

What’s also great is that you can literally place the Prometheus on a table, and it will stand by itself. This is because it has two feet-like components at the bottom. And yes, you can also fire the Prometheus when it’s in a standing position.

Also worth mentioning is that the Prometheus has a rechargeable battery pack attached to the back of the blaster. This ups the price of the blaster, but having that battery pack is a lot more convenient than messing around with a bunch of D batteries. The battery pack is also much lighter than a set of D batteries.

3. Fully Automatic

Unsurprisingly, the Prometheus is a fully automatic, flywheel-operated blaster. I mean, how else could you possibly be firing with a machine like this, right?

Operating the Prometheus is super easy and very similar to how the Nemesis is being operated, which also has a hopper system. Simply trigger the rev button to start up the flywheel, and then use the trigger to start firing.

And in case you were wondering, the Prometheus also performs incredibly well, with a super high rate of fire and excellent velocity.

Hasbro claims the Prometheus has the highest rate of fire (8 rounds per second) of all blasters when the hopper is fully loaded, and I don’t doubt that for a second. The claimed velocity in feet per second is 100, which is achievable.

With a huge 200-round capacity and a superb rate of fire, the Prometheus is a typical blaster for the heavy gunners. And because it’s fully automatic and flywheel powered, this mean machine is so much more than just a toy.

Yes, it’s expensive, but definitely not overpriced. It’s a rock-solid blaster that is incredibly fun to play with. My only piece of criticism is that this can hardly be called a Nerf blaster anymore.

I mean, where do we go from here? As you might already know, I’m a bit of an old-fashioned dude, and I still love some of the classic N-Strike blasters. The Prometheus is in a league of its own; it’s a unique type of blaster that may set the bar high for future blasters.
