About T-Minus 30
T‑Minus 30 is a single‑player city‑builder that challenges you to turn a post‑apocalyptic wasteland into a launch hub within a strict 30‑minute window. You must manage water, food, power and rocket construction while the planet races toward destruction.
The game blends resource propagation, exploration of ruined ruins and procedurally generated maps with a race‑against‑time goal of evacuating as many survivors as possible. Choices range from high‑tech hydroponics and solar farms to brute‑force 1960s‑style rockets, but no playthrough can rescue everyone.
01 / THE GUIDE
30‑Minute Time Limit
Every session lasts exactly thirty minutes, forcing rapid decisions about where to allocate labor and resources. The clock ticks down regardless of progress, creating tension between expansion and evacuation.
With the clock ticking toward the deadline, players must prioritize infrastructure that yields the most immediate benefit, such as wells for water or rockets for launch, before the world ends.
- Focus early builds on structures that generate recurring resources.
- Balance expansion with rocket construction to avoid last‑minute scrambling.
02 / THE GUIDE
Resource Propagation Chain
The core loop starts with digging wells that produce water, which then irrigates tilled earth to become farmland that yields food. This chain links water, soil and crops in a linear progression.
Later you can add solar farms and hydroponics labs to boost power and food output, but the initial water‑to‑farmland link remains the foundation for any successful settlement.
- Place wells near farmland to minimize transport distance.
- Upgrade to hydroponics only after securing a stable water supply.

High‑Tech vs Low‑Tech Rockets
Players can choose sleek generational ships powered by advanced solar farms and hydroponics, each capable of rescuing thousands, or they can rely on massive numbers of 1960s‑era rockets for brute‑force evacuation.
Both paths consume the same basic resources but differ in infrastructure demands; high‑tech ships need sophisticated power, while low‑tech rockets depend on sheer quantity of launch pads.
- Assess map resource abundance before committing to a rocket style.
- Combine a few high‑tech ships with backup low‑tech rockets for flexibility.

Procedurally Generated Landscapes
Each game generates a unique map, ranging from small arid zones with scarce resources to large forested areas filled with ancient ruins. These variations affect how quickly you can locate water, metal and plastics.
Exploring abandoned skyscrapers and junkyards yields the raw materials needed for construction, while the map size influences the distance between resource nodes and launch sites.
- Scout the perimeter early to locate high‑value ruins.
- Prioritize resource‑rich biomes when the map is large.
