Mutant Abyss: Deep Sea Horror Packed With Big Bonus Potential

I went into Mutant Abyss by KA Gaming expecting a twisted deep-sea shooter, and it didn’t disappoint. The whole vibe felt radioactive, nothing cute or cheerful here. Instead of the usual bright fish, I was picking off glowing mutants that looked like they’d crawled out of a lab spill. 

Gameplay started slow. I had to get used to enemies spawning on either edge, which took a minute to adjust to. Once I found the rhythm, I landed a freeze-shot on a tougher mutant and immediately triggered a cluster bonus. That spike in my score finally broke a quiet stretch and got me fully invested.

The Coin Collect rounds were the real tension-builders. I had one run where coins just kept dropping, each one resetting the respins, and I was fully locked in by then. Hitting the Major jackpot gave me a clean 50× win, which felt earned after several low-action rounds. I didn’t use the bonus buy, but it's there if you want to cut the grind.

I cycled through a few weapon upgrades and felt the gameplay shift each time. The basic cannon handled small fry, but once I switched to the laser, the whole pace changed, tougher mutants meant I had to time my shots and make them count. The scrolling screen gave me just enough freedom to feel like I was hunting, not just tapping.

What made the experience stand out was how mean everything looked. This isn’t a background detail, it actually changes the tone of the session. You're not just fishing for wins; you’re surviving a mutagen-infested ocean. That alone made it more memorable than most fishing shooters I’ve played.
