Description

Short

Deepstrata is a 2D mining game. You fly a pod into the crust of Luna, Mars, Io and Callisto, drill for ore, get it back to the surface before the fuel runs out, and spend the money on a better rig.

Demo

The Deepstrata demo is the first contract: Luna. Learn the pod in a training session, then drill 220 metres of strata, sell the haul, upgrade your rig and find a claim. A Sentinel sleeps at the bottom. Wake it and fight, or feed it and walk away.

Long

Deepstrata is a 2D mining game. You are a contract driller for REGOLITH Deep Extraction. You fly a pod into the crust of Luna, Mars, Io and Callisto, fill the cargo bay with ore and come back up before the fuel runs out. Then you buy a better drill and go deeper.

You can drill through almost everything. Fuel burns the whole time you are underground, and a full cargo bay makes the pod heavy. Dig under a boulder and it falls on you. Drill into a gas pocket and it explodes, along with every pocket next to it. Some dirt hides a cache: an ore vein, fuel, a relic, or lava.

Some rock formations have a rule you can learn. Do it right and you get a bonus on top of the ore. Rush it and the formation hurts you.

There are five story contracts, on Luna, Mars, Io, Callisto and a site called The Rift, plus an open contract with no quotas. The story comes over the radio while you work.

Further in, you build a base underground. At night, creatures attack it. You have to defend the base and still keep drilling for resources.

Each site has a guardian asleep at the bottom. Shoot it and you get a fight. Or bring it the ore it wants and feed it instead. Both ways finish the contract.

Every contract can be played on Peaceful, Standard, Hard or Brutal. Peaceful has no combat at all. It's there if you only want the mining.
