ChromaGun asks players to build a robot, paint it with colors, and fight waves of enemies with a paint gun. That premise sounds simple. It is not.
The game launched in 2016 for PS4, PC, Mac and Linux, and it remains one of the stranger shooters to come out of that year. It is a tower defense game dressed up as a first-person shooter, and it mostly pulls it off.

Building the Robot
Before combat starts, players pick a chassis, add arms, and then paint over the whole thing with a color wheel. This is not a cosmetic choice. The color you choose determines what kind of damage you deal, and each color responds to a different enemy type. Blue hits fast, red hits hard, green hits everything.
The build screen is where ChromaGun shows its personality. Players can stack weapons, armor, and special items on top of the base robot, and the game tracks how effective each combination is against each wave. The system rewards experimentation, and the best builds often come from trying something nobody expected.
“Build your robot, paint it, and fight waves of enemies.”
That line sums up the whole experience. It is a mission statement, and ChromaGun follows through on it.
The Color System
The core mechanic is the paint gun. Players hold down a button to charge up a shot, release it to fire, and then watch as the color they chose reacts to the enemies in front of them. Green enemies take extra damage from green paint. Red enemies take extra damage from red paint. The system is simple to explain and complex to master.
The difficulty curve rises fast. Early waves are easy to clear, but later waves mix enemy types and force players to switch colors mid-combat. A player who sticks to one color for too long will lose. A player who switches too fast will lose just as quickly.
ChromaGun does not hold the player’s hand. It tells the player what works, then leaves the rest to chance.
Tower Defense Roots
The game borrows heavily from tower defense games, and it shows. Enemies move along fixed paths, spawn points are marked clearly on the map, and the player’s job is to stop them before they reach the end. That structure gives ChromaGun a rhythm that most shooters lack. Waves arrive at predictable intervals, and the player can plan their build around them.
The best fights in ChromaGun happen when the enemy count spikes and the screen fills with color. Watching a robot covered in blue paint mow down a wave of green enemies is satisfying, and the game does not hide the numbers behind it. A counter tracks kills, and a separate meter tracks the effectiveness of each color choice.
Performance Across Platforms
ChromaGun runs on PS4, PC, Mac and Linux, and the performance varies across those platforms. The PS4 version holds up well in single-player mode, though multiplayer sessions can lag when several players join at once. The PC version offers the smoothest experience, with higher frame rates and faster load times. The Mac and Linux versions run at a lower pace, with occasional stuttering during busy combat scenes.
The game supports local co-op and online play, and both modes work. Playing with friends is where ChromaGun shines brightest. Splitting the enemy count between two robots changes the strategy entirely, and the game rewards players who coordinate their colors instead of working in isolation.
Replay Value
ChromaGun is short by modern standards. A full playthrough takes about six hours, and the main campaign ends quickly. The game makes up for this with a challenge mode that adds harder waves and tighter time limits. There is also a sandbox mode where players can build their own levels and share them with others online.
The replay value comes from the build system. There are dozens of chassis, weapons, and items to try, and the game does not lock any of them behind a paywall. Everything is available from the start, and players who want to spend time building a perfect robot have plenty of room to experiment.
Sound and Look
The visual style leans toward bright, cartoonish colors, with robots that look like they were built from toy parts. The sound design matches the look, with cheerful music and sound effects that play up the game’s light tone. Nothing here feels grim or serious, and that is a deliberate choice.
ChromaGun is not trying to be a gritty shooter. It wants to be a fun one, and it succeeds at that goal.
Where It Falls Short
Not everything works. The game’s difficulty spikes can feel unfair when the enemy count is high, and some waves are designed to punish players who have not tried every color combination yet. The paint gun controls are occasionally awkward, especially during busy fights when the screen is filled with targets. And the short campaign length means there is less content than players might hope for.
These are small complaints, but they add up. ChromaGun is a polished game with a solid idea, and it executes that idea well. It just does not push far enough in every direction.
Final Score
ChromaGun earns a 7.4 out of 10.
| Platform | Performance |
|---|---|
| PS4 | Solid, minor lag in multiplayer |
| PC | Smooth, best performance overall |
| Mac | Lower frame rate, occasional stutter |
| Linux | Lower frame rate, occasional stutter |
The game is worth playing for anyone who enjoys unusual mechanics and creative builds. It is not a game that will appeal to everyone, but it knows exactly what it wants to be and delivers on that promise. The paint gun system alone is worth the price of entry, and the build screen offers hours of content beyond the main campaign.
ChromaGun is a strange, colorful shooter that rewards curiosity. It is best enjoyed with friends, and it is best remembered for its paint gun.
