Feel free to add more btw
Gear Up is a game where you can either capture certain points to win, play in a TDM, or play in FFA. With quite a bit of parts you can use, once you buy them with in game currency you get with how well you do, you can have quite a bit of vehicle combinations. With various propulsion methods, you can change your combat strategy by being a sniper who can get in water without drowning, or climb on walls with your spider legs. This game is extremely fun, and it's definitely worth trying.
Imagine minecraft and Gear Up had love. You get Robocraft! With even more infinite possibilities of machine building, you can buy pieces and stick them together as much as you want as long as your machine's CPU can handle it. CPU basically decides how much stuff you can put on it. Also really fun, try it some time.
