Future Problems

A week goes by without anyone on the Earth except for you. You are now the richest man alive and have access to anything you desire, the only remains on the Earth is a tiny rover left behind when another planet took over and transferred everyone to their world. Another week passes and you have gotten very sad and depressed knowing that everyone you know is now unreachable and you can't ever see them or get them back in your life ever again. Instead of going on a walk to make you feel better, you decide to use the rover that the foreigners left behind instead. You notice a strange row of buttons on the dashboard of the rover, without knowing the danger of each one, you decide to push one and suddenly the ground begins to shake. Before you know it, a huge object appears above you, something that looks like battle tank. Using a teleporter you go into the battle tank and decide to go and try to find all of the people you love and know. Going over to another dimension isn't easy for the state in time. After a month of traveling through only a couple of dimensions, you notice a planet that has some Earth like features. While flying into its atmosphere your tank starts to lose control. One wrong move can sacrifice your life.
