Background

Here are the screens from my first "game" built in UE4. It's technically a game but not particularly impressive. Since it's the first game I've ever built, I'm pretty happy with how it turned out.

Here's a video of the gameplay:

Gameplay

I changed the name to "Pathogen Hunter" last minute since that was more in line with what the game is about... shooting pathogens out of the bloodstream.

Your goal is to shoot the pathogens (the green blobs) out of the bloodstream. If you misfire and hit the patient too many times, you lose. If you shoot enough pathogens to score 1,000 points, you win! Technically, that's all you need to have a "game".

Behind the Scenes

Here's the build in UE4. It's just a BSP tube with a particle emitter that showers down red blood "cells". A HUD overlay handles the scoring and crosshairs.
