Tanki Online is a third-person shooter game. I joined in 2013 and played it for a few years. I didn't touch it since 2017 cause it had too many p2w mechanics and it just kept going downhill, but now I decided to visit and see what's going on. The game still had a lot of p2w mechanics. You have to spend money on crystals to get all those powerful/expensive items (drugs, protection, drones, etc). I'm sure there's some rich guys out there who already have everything (or everything they want), otherwise you will be thrown into a match with 90% of the players using drugs and drones, and you'll end up getting ****ed on. However, you can play pro battles to avoid druggers. XP battles are good, but some teammates in XP battles are not very nice.
I don't recommend it if you can't afford all those p2w items, and the game's popularity is still declining.
