Zombie Mission 8 is the next part of the adventure. This time, it's on Mars. Zombies have invaded the Mars Colony and captured scientists and workers. You need to rescue them using weapons and vehicles. Don't forget to collect objects as you go. Watch out for meteor showers; when you get a warning, head to the shield cabin. To improve your fighting abilities, visit the MARKET and make upgrades using the coins you earn between levels. You'll even jump on walls and use gravity switches to keep the mission going.
