Relic are giving away their 2013 real-time strategy game Company of Heroes 2 free for the rest of the weekend.
Set in World War II, Company of Heroes 2 focuses on the confrontation between Germany and the Soviet Union on the Eastern Front. Although not quite as accomplished as the original Company of Heroes (2006), Company of Heroes 2 features superior graphics and new gameplay features such as simulating freezing cold weather and the impact of that on troops and vehicles.
Relic have also bundled Company of Heroes 2's numerous expansions and DLC into a single bundle for less than £5, including the very large, game-sized Ardennes Assault expanson which adds a persistent campaign map mode.
You can get Company of Heroes 2 here and the DLC here.
