“Бро, я прогорел на баблхэдах, не советую в них инвестировать”
“This game has become what I expect of tower defence games, from creating your own path to in-round participation Every level solution you find becomes personal with so many different ways to go about it I recommend…”
“Looks a bit on the uglier side and the FOV is atrocious even when maxed out but it ain't half bad. Game's balancing breaks like a twig if you utilize DLC though so you might want to avoid utilizing them”
