Quick Guide

  • The Upgrades room opens for 250 Cash — it is also where the tutorial ends.
  • First-round upgrades include Faster Cash, More Cash, and Walk Speed.
  • The developer confirms multiple upgrade trees that expand as you descend; official per-tree numbers are not published yet.
  • Order matters: Cash generation first, because steps get pricier every layer.

How the Upgrade System Works

Upgrades are the engine of Depth Incremental. The Upgrades room sits behind a 250 Cash door near the start of the pit, and it is the game’s first real decision point: inside, Faster Cash, More Cash, and Walk Speed each compound for the rest of your run.

Past that room, the official game description confirms “expand many different Upgrade Trees” — trees open up as you descend to new layers. The developer has not published a full tree list with names and prices, so this guide focuses on what is verified: the starting trio, the priority logic that holds at every depth, and how trees interact with Rebirth Guide.

Why order beats totals

Steps get more expensive with every layer. A small income upgrade bought early funds hours of descent; the same upgrade bought late is a rounding error. The Best Upgrades ranks the opening buys.

The Starting Trio, Ranked

  1. Faster Cash — buy first (250 Cash)Raise how quickly Cash arrives. Every later purchase gets cheaper in real time.
  2. More Cash — buy secondRaise how much each payout gives. Pairs with Faster Cash to outscale step prices.
  3. Walk Speed — buy for comfortFaster movement shortens trips between the stairs, the Upgrades room, and the DIRT FOSSILS room (2,000 Cash unlock).

Trees, Luck, and the Long Game

Trees open with depth

Deeper layers unlock more trees — the official description promises many. Names and prices are being verified as players reach them.

Luck trees pay in fossils

Luck multiplies rare Fossil and Title odds. Stack tree bonuses with the active code from the Codes.

Income trees beat step rush

Whatever a tree costs, income scaling is what makes the next layer affordable — see Unlock Next Layer.

Rebirth resets, strength stays

Rebirth trades your run for permanent power — tree progress rules are documented in the How to Rebirth.
