With the 1.5 update, World of Tanks brings a few new Swedish medium tanks that feature hydropneumatic suspension, the ability to choose which map to avoid in standard battles, changes — mainly nerfs — to Japanese heavy tanks, the infamous FV 4005, and the artillery branch. A special deal for Twitch Prime members is also available.
