I had a rental of this. Totally troll gun. I’d never buy it
after a year I have 20 battles with this thing… And just once was fun to play
well, especially after BZ-176 came out, Caliban is totally powercreeped. yes, it has those two shells, but BZ has bunker turret and can be faster with the boosters. and lets not forget the way worse gun stats (dispersion 0,38 vs. 0.25 and 0.58 acc vs. 0.44 because reasons!
IMHO absolutly not worth it!
the 3d style is in where you buy other styles.. its a bit ridiculous honestly.
It’s an ugly 3D style, too. Gimmick style for a gimmick tank. =/
I think I saw one of these tanks once in a battle.
