Shootup.io is an engaging zombie shooter game that throws players into a perilous situation in a mysterious town overrun by zombies. Their only option is to fight back and eliminate the undead hordes. Players can choose to either fortify a base for defense or take a more aggressive approach by using vehicles to mow down zombies. Cooperation with friends or engaging in PvP with other survivors adds an extra layer of excitement to the gameplay.

To succeed in this apocalyptic world, players can unlock various bonuses, ammunition, turrets, and landmines by achieving milestones and collecting items scattered around the environment. Tips for survival include maintaining a safe distance from zombies to avoid getting attacked, being mindful of making noise when shooting or driving to avoid drawing unwanted attention, and utilizing drift (Shift) when a vehicle gets stuck.

Additionally, players can strategize to accumulate kills and unlock upgrades or new buildings every 100 zombies eliminated. Ensuring the availability of sufficient oil for vehicles and periodically shooting to keep zombies at bay are essential tactics for survival. Moreover, the game allows players to coordinate and team up with friends by utilizing the “Team with your friends” button, enhancing the cooperative gaming experience.

The game controls are intuitive, with movement options using W, A, S, D, Z, Q, S, D, or arrow keys, shooting with the left-click, and placing buildings with the right-click. Interaction is facilitated using the SPACE bar, running for evasive maneuvers, drifting in cars with Shift, and switching weapons and buildings through numerical keys and mouse wheel, respectively. By leveraging these controls effectively, players can aim for high scores and dominate the challenging zombie-infested landscape of Shootup.io.
