The KV-220 Beta Test is a Tier V Soviet Premium Heavy Tank. It is currently not available in the in-game store.
Identical in all ways to the KV-220. It was granted as gift to beta testers on the RU and SEA servers. This tank is equipped with a KV-3 hull, KV-1 turret, and has decent guns for it's tier. It has a thick all around armor proving impervious to some lower tier Light Tank and can be a fun tank to play at the front lines. Soak up damage effectively and you will earn lots of credits, though you may not do a lot of damage due to lack of penetration, damage, and accuracy.
