Abyssal Merge
SteamAbyssal 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.
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.

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.

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.

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.

In true roguelite fashion, a failed run is not the end. The money earned from your merged fish can be spent in the Permanent Upgrade Store. Boost your stats and upgrade your ship to ensure your next adventure takes you even deeper into the abyss.

Beating the final boss is just the beginning. Victory unlocks new boats, each providing a significantly higher level of challenge. These vessels aren't just skins - they require you to craft and master entirely builds.

Once you have purchased every permanent upgrade, you unlock Endless Mode. With your meta-progression complete, only pure skill remains. Push your build to its absolute limit and compete for the high score against infinite, escalating waves of monsters.
