Ever since this update I couldn't get past the 100th wave... Enemies have a clear advantage now on every single option. Pak38 fire all the time and the AT rarely fires.
For the next game make special soldier classes and mabey make them customizable with assault rifles, SMGs, sniper rifles, ghillie suits mabey even rockets and flamethrowers... Make tanks more expensive to get rid of extensive money mabey? And give the Chinook attack capabilities and able to take off once landed.
