3 DAYS TO SURVIVE 2: APOCALYPSE

As you are about to make your way back into Earth's atmosphere, you realize something is not right. With the super telescope on your spaceship, you see that there are zombies everywhere. You even see giants, crushing everything below them.
You realize that there was an apocalypse and that if you land with your spaceship now, you will die very quickly.
What happened to all your armor? Well, you thought that it would just add weight to your ship, so you got rid of it, thinking that it would be useless.
Therefore, you have to land on another planet and gather resources, just like last time.
You also realize you do not have much oxygen, and you will have to go home in 3 days (1 hour real life time) to fight off the zombies.
Good luck!
