In GravBoost, gravity is your greatest ally and your deadliest foe. Master the art of the gravitational slingshot to intercept orbital targets. Manage your fuel and time wisely in this physics-driven space sim where precision is the only way to survive the cosmic pull.

Master the Elegance of Orbital Mechanics GravBoost is a physics-driven space action sim that challenges you to harness the most fundamental force of the universe: Gravity.<video class="bb_img" autoplay muted loop playsinline poster="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4313700/extras/7c836ac71020a352caa04088fa7597a1.poster.avif?t=1770633848" width=800 height=450 ><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4313700/extras/7c836ac71020a352caa04088fa7597a1.webm?t=1770633848" type="video/webm; codecs=vp9"><source src="https://shared.akamai.steamstatic.com/store_item_assets/steam/apps/4313700/extras/7c836ac71020a352caa04088fa7597a1.mp4?t=1770633848" type="video/mp4"></video>Core Mechanics:<ul class="bb_ul"><li>Gravitational Slingshots: Use planetary gravity wells to gain velocity and alter your course. Every degree of entry matters—miss the mark, and you'll either crash into the surface or drift eternally into the void.</li><li>Resource Management: Time and fuel are your only lifelines. Every thruster burn must be calculated. Precision is not an option; it’s a necessity.</li><li>Destroy &amp; Replenish: Hunt down synchronized orbital targets to scavenge fuel and extra time. Chain your takedowns to keep your mission alive.</li></ul>Key Features:<ul class="bb_ul"><li>Pure Physics: Experience a flight model governed by inertia and universal gravitation.</li><li>Risk vs. Reward: The closer you skim the planet, the faster you go—but the pull of the abyss is never far away.</li><li>Minimalist Aesthetic: Immerse yourself in a deep, rhythmic cosmic atmosphere designed for focus and flow.</li></ul>
