If you like free games and you're into tanks, then this is the game for you.
World of Tanks has just arrived on the PS4. Did we mention it's totally free!? Here's a very loud trailer, which is pretty fitting.
World of Tanks first launched in Russia back in 2010 and the title tells you pretty much everything you need to know. There are 130 tanks to choose from which you take into the field in 15 v 15 player online battles. Shoot shells at other humans, try not to get hit by their fire, and attempt to win a lot. This earns you experience points which you can then spend on faster tanks, stronger tanks, prettier tanks, MOAR TANKS!
Repeat, and maybe use real world money if all that is taking too long.
World of Tanks is totally (mostly) free and on PS4 now.
