[GDC 2025] “EOPRISM” Hands-On

When you look at testimonials on EOPRISM‘s Kickstarter, it’s a wonder why this game would appeal to anyone.

“It’s like DOOM, but with algebra!”

I’m not a DOOM guy and I’m not a math guy, but I definitely think EOPRISM has some legs.

EOPRISM is a first-person shooter where you have to solve expressions to kill enemies. You’re equipped with a gun with ammo numbered 0-9, and you have to scroll (assuming you’re playing with a controller) with the left and right bumper to shoot at incoming enemies with the appropriate number. So if you see an enemy coming at you labeled 1+1, you have to cycle to 2 before shooting at it. (1 – – 1)? Two negatives make a positive, so it’s 1+1 again, which means you have to shoot with 2.

The demo featured at The Mix during GDC was simple enough, but Josh Delson, the founder of Unexpected Accessories, said they go as high as calculus. I stopped at calculus in high school, so I don’t want to imagine what those expressions or equations look like. That aside, each enemy only took one “bullet” to kill, so it wasn’t anything too difficult.

What they featured was essentially an early level in the game’s story mode. You go from a hallway, to a basketball gym, to a theater, shooting all the evil calculators in your path. After a simple boss fight in the theater, the level and demo ended calculating (hey, more math) stats like how long you’ve spent in the level, the shots you fired, your accuracy, your equation accuracy, the times you jumped, and other stats including your overall grade. I got an A+, so I’m really feeling like a genius right now. Just like Mr. Abacus!

Math aside, and I know people do like math, this colorful adventure is looking to come with a Challenge Mode in the future. The Story, Practice, and Challenge modes each contain procedurally generated math equations and infinite playthroughs. My favorite part about the game is that it’s absolutely “pun”tastic. From the infinite zeros, to PEMDAS rule, or the quadratic equation sung in the melody of Frosty the Snowman, Unexpected Accessories has a lot of zanyness to work with, and hopefully the Kickstarter campaign allows them to get there.

You can still download the demo on Steam. In the meantime, you have a little more than a week left to help fund their goal. Help them get there, because the order of operations need to be subtracted!
