Amborettio II: Deep Relay

Amborettio II: Deep Relay is a top-down mining, combat, and extraction adventure set deep beneath the surface. Each expedition generates a new cavern filled with destructible terrain, valuable ore deposits, hostile spirits, and a relay waiting to be powered.
Mine your own paths through the cave, collect resources, deploy torches to push back the darkness, and construct automated turrets when you need extra firepower. Deposit enough ore to activate the relay and prepare for the creature it awakens. Defeat the boss, return to the relay, and extract to secure your progress.
Ore deposited beyond the relay's required quota becomes a persistent reserve that can help fund future expeditions—but falling in battle means losing that reserve. Enemies can pursue you through the cave, break through terrain, and even launch ranged attacks, while medkit drops may give you the extra health needed to survive.
Every run is another descent. Every cavern is temporary. Get in, power the relay, and get back out.
