The game control of Downhill Smash is rather conventionally simple for mobile game players who mainly tap and hold in-game targets through screen-touching motion control. The goal of the game is to manage both zombie and landslides at the same time. To achieve this two-front goal, players must think strategically and take movement accordingly. On the one hand, as they move down the hill by gravity, they’ll encounter large crowds of zombies moving upward towards the player. In this confrontation, players have only one goal— to eliminate those zombie enemies as many as they can. The most effective weapon to serve this purpose is the gigantic round stone known as the “boulder” that can crush through the zombie army. There are also other smaller-sized weapons attached to the boulder pack such as axes and fuel. Axes can enhance the damage level the boulder causes to enemy targets, while fuel is of great importance in adding the capacity of the racing session, because the gameplay ends when the fuel runs out. There are also many other useful tools and skills players can add into their arsenal for each level of challenge. Energy kit helps them run down faster to save fuel and “mass” tool powers up the damage too. Plus, players also need to consider their escaping skills in case of landslides. Jumping is a key motion they need in order to dodge that. Therefore, as players proceed into higher levels, they must prepare their boulder weapon kit carefully and include necessary items and skills for a safe ride. Also, players can actively participate in various voluntary missions and quests to earn more rewards, which can be useful in upgrading in-game weapons and skills needed for harder challenges.
