Tips & Tricks for Astro Builder
To achieve the highest altitude in Astro Builder online, balancing your rocket's weight is crucial. Don't just stack the heaviest engines; ensure you have enough fuel capacity to sustain the extra mass. During the flight phase, avoid holding the thrust button down constantly. Instead, use controlled bursts to maintain momentum while conserving precious fuel. Pay attention to the dynamic flight HUD to monitor your speed and air density. Lighter rockets often perform better in the lower atmosphere, so experiment with minimalist designs.
