Gear Up is a totally f2p tank fighting game. Players are able to customize their tank to fit a play style or to just be different. I've played roughly 6hours already and it remains to be engaging. Furthermore unlike most multiplayer games the community is really chill; rarely see any choice words in chat.
I'm currently thinking of changing my build because a glass cannon build seems to dominate more than some players can stand...and 5 hours of playing the same build while laughing at my shenanigans is getting a tad stale. I'm most likely going to miss its speed compared to other tanks but maybe I'll like the build I'm thinking of more.
Anyway I suggest checking it out. There's a small learning curve as steering a tank is a tad mind bending at first. Additionally the starting gear is okay but you need to pick battles wisely or don't miss. Gearing up is fast as a few games can afford all the parts you need to build your preferred tank.
