I've been playing Tundra for quite a long time and very actively.
positive; once in 100 battles you will not be killed by a rat from under a bush 2 km away from you
map; there is only one satisfactory map in the game - Poland (and only after the change) all the others, especially Karelia and Stalingrad, are an unplayable bush rat breeding ground (if anyone knows a card maker, please pull him out of the basement)
equipment: zero balance, the most adequate Shermans, T34 , Abrams, Leopards, everything else is either for the fierce rats of donators or cheaters. aircraft RB, AB. I tried it once and scored, the gameplay is boring and dreary (the balance is also shit)
penetration and damage system: here there is only mate penetration with a 76mm cam the crew turned yellow (pissed themselves from laughter)
graphics: ok but try to play possible only at the lowest
result: if you want to burn money, time and especially nerves, this game is for you
