Company of Heroes 2 @ HumbleBundle
Regularly $19.99. Must log into free HB account to add to library. Very positive reviews on Steam. World War 2 RTS with tanks, artillery, etc. More info @ Steam: http://store.steampowered.com/app/231430/Company_of_Heroes_2/
FYI: Other sites have posted the redemption deadline is December 30th, 2017 at 10:00 AM Pacific…but I haven’t seen that on Humble Bundle myself. Add it to Steam soon to be safe.
