Quick answer: Abyss Expedition is a single-player roguelike RPG for Android and iPhone, made by Jaehoon Lee, a solo developer in South Korea who publishes as SONGISTORE.

It is free to download, with ads and optional in-app purchases that include random items.
Watch: 80 seconds of gameplay
The developer supplied this silent gameplay clip. It shows the first equipment choices, backpack placement, normal battles and the first king fight on floor 5. Combat is at its recorded speed.
Footage: Abyss Expedition / SONGI STORE. Recorded 23 October 2026. According to the developer, it was captured on a local build, not on a phone, and no purchases, rewarded ads or added items were used. The build includes a small tutorial fix that is not yet in the public store versions.
The loot board: the core idea
Many mobile RPGs give you random rewards with no choice. Abyss Expedition gives you a visible, limited board of prizes. You draw from it one item at a time. Each item you draw is removed. So after every draw, you make a decision:
Keep drawing: the item you want is still on the board.
Clear the board: only a few slots are left, and drawing them all gives you supplies and a choice of upgrade for this expedition.
Change the board: nothing left is useful. A new board has in-game conditions and costs, and it is not always better.
This is a push-your-luck system. Because you can see what remains, you can plan with information, not only luck.

Our view
Abyss Expedition is a small and very new release, with 500+ downloads at the time of writing. Its loot board gives a real decision on every draw, which is more interesting than a plain gacha pull. The risk is the random paid items. If you play, set a spending limit and check the store details first.
