1 · PRODUCE. Buy accelerators to make antimatter and power to run them. Output scales from picograms to grams a day.

2 · CONTAIN. Antimatter decays fast — your max stock ≈ output ÷ decay. Buy traps (storage) and keep cooling powered, or containment integrity falls and you breach, venting your stock.

3 · RESEARCH. Cut decay, boost output, unlock better tiers and faster drives.

4 · LAUNCH. Pick a drive archetype — Catalyzed needs little antimatter but is slow; Pure Photon is fastest but brutal. The relativistic calculator quotes the real antimatter cost. Hit the target, launch, and watch ship-time and Earth-time diverge.

Real talk: CERN makes a few nanograms of antiprotons per year, and one gram annihilating releases more energy than the Hiroshima bomb. You are attempting the impossible — that's the point.
