Today I went back to tier 1 because I wanted to get more points by killing more people. With the points, I'll be upgrading to tier 3 armour, and also tier 4 weapons.
Today I finally figured out why I was tier 1 for the longest time. Today I upgraded from my crappy car into a tank. I don't really know what else is special, other than it being a tank. It does pretty high damage, and it's can take a lot of hits from other robots.
I honestly don't know what special about this build. For now I'm just messing around, and trying to upgrade my guns, blocks, etc to make it better and stronger. Once I get it to higher tier, i'll make it into something more special.
