Moomoo.io

Moomoo.io is a very popular game. You play starting off as level 1 and then becoming level 20, which is the last level. You get weapon updates every time your gold becomes better. You can kill people and build forts in the game. It is very fun too. It has one gun. That makes it relate to surviv.io. You need lots of resources to start a base. Here are some photos:
