About this game
◆Features
『ABYSS SEEKER』 is a twin-stick survivor shooter game where you control your character freely using two sticks, survive waves of enemies within a time limit, and defeat the boss that appears in the final wave to progress to the next dungeon.
The shots fired by the player character can be customized by combining items that appear during level-ups, allowing you to alter their properties and fight with your "unique shot." Defeat the relentless forces of darkness and make it out alive!
※This work is a spin-off based on "HEAVEN SEEKER ――The Savior of This Cruel World." It can be enjoyed as a standalone title.
◆Stronger Bosses
Area bosses resembling those that appeared in the Sky Castle have been influenced by the Abyss, becoming more powerful and attacking anyone who dares to enter the dungeon.
Dodge the barrage of bullets unleashed by the boss and take them down!

【UPDATE】Ver1.2.0 Realese!
Hello, this is the Abyss Seeker development team. We have released Update Ver.1.2.0. ◆ New Character: "Pentas P (Prototype) 24" has been added. {STEAM_CLAN_IMAGE}/45259002/5f987023e6fd58c0af06d7106e0fb4e874afceb1.png The "seventh" seeker found at the bottom of the great abyss. She was once an explorer from the Mechanized Nation and a prototype of the Pentas Series, a line of mechanical soldiers designed specifically for the conquest of the Sky Fortress. As her name suggests, she was the 24th unit in the series. However, the prototype models had inherent design flaws, and these issues became apparent with her unit. As a result, before she could even be deployed for the Sky Fortress mission, she was deemed a failure and discarded into the depths of the abyss by the nation. Although Pentas P24 was nothing more than scrap, she somehow reactivated. The reason for this remains unknown. It is unclear if the term "alive" is appropriate for her, but a large portion of her memories have been lost. ※ Pentas P24 becomes available for use after clearing the Deep Abyss - Layer 5: Abyssal Ruins. ◆ New Grimoire Added: The following new Grimoire makes its first appearance in Abyss Seeker. It can be purchased from the Shop for use. {STEAM_CLAN_IMAGE}/45259002/52a3b316cabaded880a63b9e2b73d4e4e6a0f885.png ・PLASMA SHOT ◆ New Artifact Added: The following new Artifact makes its first appearance in Abyss Seeker.
