ABYSSAL FRONTIER｜放置採掘ゲーム

[This is the bottom of the ocean where even light cannot reach]
ABYSSAL FRONTIER is an idle/incremental game where you develop a dome city in the deep sea.

■ Simple yet profound core loop
- Tap the dome to mine ore
- Automatic production with facilities such as mining drones, hydrothermal turbines, and kelp farms
- Production decreases if power does not meet demand. Grid management is key.
- Population = labor force. Increase it with residential pods and ensure oxygen does not run out.

■ "Diving" system to cross ocean trenches
Research the deep-sea diving plan, then collapse your city and venture into deeper trenches.
The acquired "cores" make the next cycle stronger through prestige design.
With the constraint of "Challenge Dive," core acquisition is up to x1.6.

■ Deep-sea creature collection
Dispatch exploration submarines to discover resources and unknown deep-sea creatures.
Duplicate discoveries allow you to grow up to Lv5, and bonuses remain even after the cycle. At the deepest part of each trench awaits the "Master of the Trench"—collect all 10!

■ Artifacts and Weekly Ranking
Excavate and equip up to 3 artifacts.
Compete with admirals worldwide in the weekly rankings based on total production capacity (nickname registration required, resets weekly).

■ Leave it Alone!
Cities operate even when offline (up to 8 hours, extendable with research).
Automatic construction and automatic diving make patrolling easy.

■ 3 Language Support
Japanese / English / Simplified Chinese

Completely free to play (with ads and in-app purchases).

Deeper, deeper and deeper—what awaits you in the abyss of the trenches?
