Abyssal Merge is a fast-paced roguelite shooter where your survival depends on your ability to multitask. As a lone captain in the heart of a monster-infested ocean, you must defend against waves of creatures while simultaneously catching and merging the fish in your net. Fight to Protect the Net From the top of the screen, horrific sea creatures will try to get into your net. You are the only line of defense. Protect your haul by shooting enemies in fast-paced, arcade-style combat. Merge to Grow Stronger While fighting for your life, you must manage your net at the bottom of the screen. Merge fish to create larger, more valuable catches. The more you merge, the stronger your boat becomes, giving you the power needed to survive the escalating waves of enemies. Choose Your Build Every level-up is an opportunity to choose from a variety of upgrades to define your playstyle. Whether you focus on raw firepower or net efficiency, every run offers a new opportunity to experiment with a unique, game-breaking build. Defeat the Abyssal Bosses The deeper into the ocean you get, the more terrifying the horrors become. Prove your skills by defeating massive final bosses to secure a massive payout for the fish in your net. Die, Buy, Repeat In true roguelite fashion, a failed run is not the end.
