The folks at THQ have released the first trailer for Company of Heroes 2
that covers some of the new technology and tactics that will be available in the new game. Specifically they cover Truesight (a new take on fog of war, the new vaulting ability (how infantry can actually climb over things), and the Cold Tech (the new weather engine which impacts how the environment impacts player).
From the early looks of it the game is coming along really well which is good as the original Company of Heroes
was one of the best RTS games of all time. The game should be available in early 2013 for the PC.
