Plan your next T-Minus 30 session

Our independent guide breaks down T‑Minus 30’s core systems so you can make informed choices without relying on trial‑and‑error. By examining each mechanic’s strengths and trade‑offs, you’ll develop a play style that fits the map, resources and your preferred evacuation method.

01 / THE GUIDE

Assessing Map Type

Compare an arid map’s limited water sources with a forested map’s abundant biomass. Note how each environment shifts the balance between early wells and later hydroponics, then decide which rocket path suits the terrain.

  • Focus early builds on structures that generate recurring resources.
  • Balance expansion with rocket construction to avoid last‑minute scrambling.

02 / THE GUIDE

Balancing Infrastructure and Launches

Track the time spent building solar farms versus constructing launch pads. Record how each decision impacts the number of rescued evacuees, helping you find a sweet spot between power generation and rocket readiness.

  • Place wells near farmland to minimize transport distance.
  • Upgrade to hydroponics only after securing a stable water supply.

03 / THE GUIDE

Resource Chain Efficiency

Map the flow from wells to farmland to food. Experiment with placing wells adjacent to farms versus spreading them out, and observe any differences in resource delivery speed.

  • Assess map resource abundance before committing to a rocket style.
  • Combine a few high‑tech ships with backup low‑tech rockets for flexibility.

04 / THE GUIDE

High‑Tech vs Low‑Tech Comparison

Run two short sessions: one focusing on generational ships, the other on 1960s rockets. Compare total rescued populations and infrastructure costs to see which approach aligns with your play preferences.

  • Scout the perimeter early to locate high‑value ruins.
  • Prioritize resource‑rich biomes when the map is large.

05 / THE GUIDE

Achievement Targeting

Select a specific Steam achievement, such as rescuing a set number of people. Play a run aimed at that goal and note which building priorities most directly contribute to its completion.

  • Aim for achievement thresholds that align with your play style.
  • Check the leaderboard after each run to gauge improvement.
