Vehicle engine sounds updated??? Which ones?
Hoping for as many as possible over here 😀 Sure the graphics update back then was great,but im hoping there will be a sound focused update/overhaul some day^^
But i guess its could be just another phrase for “added sounds for tanks with damaged tracks driving with the new track mechanic” sorta thing ^^
My older brothers calculator from 1991 makes better sounds than WoT
aaand still not fixing any of the real problems like OP premium tanks, arty limit, gold spamming.
