From the makers of Cut the Rope comes Downhill Smash, a physics-based destruction feast that is as chaotic as it is addictive. The game puts you behind a giant, rolling boulder-machine in a post-apocalyptic world infested with zombies. Your goal? Smash everything. The physics are the star here—watching a structure collapse or a horde of zombies fly into the air as you plow through them is immensely satisfying.
The customization loop is fantastic. You’re constantly unlocking new weapons, from saws to lasers, and upgrading your boulder’s speed and power. It does get a bit 'grindy' in the later stages, and the avalanche chasing you is a brutal motivator, but the core loop of rolling, smashing, and upgrading is incredibly polished. It’s a loud, proud, and violent (in a cartoonish way) physics playground that feels great to play.

Post-Apocalyptic Racing Levels
Focus on upgrading your boulder's engine first to stay ahead of the avalanche. Once you have speed, invest in side-mounted saws to handle large structures.
Giant zombie bosses require specific timing. Use your manual weapon triggers to strike their weak points while maintaining your rolling momentum.
Keep your momentum up and use speed boosts. If you get stuck on a building, use your weapons to clear it quickly.
