What is T-Minus 30?

This single-player, isometric city builder takes place on a ruined Earth nearing destruction. Each run uses a procedurally generated landscape where you reclaim materials, grow food, extend water and power networks, and build escape rockets. You can construct large numbers of older rockets or invest in advanced evacuation ships.

For you if...

+you enjoy optimizing resource production and building placement
+you like adapting construction plans to terrain and scarce resources

Not for you if...

−you prefer building at a leisurely pace without deadlines
−you want an open-ended city you can develop indefinitely

What players say

92% of 175 reviews are positive

Players praise the evacuation premise and how much city-building fits into a short session. Some find that production routines become repetitive once they establish a strategy, with too few meaningful decisions.
